Compute Your Lost Potential Revenue Instantly – Mag-Probe Interactive Downtime Spreadsheet

Mag-Probe Interactive Downtime Spreadsheet and Video Below

The profits generated by reduced troubleshooting time make the Mag-Probe the obvious choice for a CEO, President or Owner, of any service or manufacturing company.   Why?   Because typically the return on your Mag-Probe investment will be one test.   The Mag-Probe is guaranteed to conduct 5,000 five second operations. So after the first test, you can begin recovering your investment.  NOT BAD SINCE YOU WILL HAVE 4,999 MORE TESTS AVAILABLE


An aircraft mechanics worst nightmare is to get a call from the flight crew that they can hear a relay cycling on and off (click…click…click….)

Not only is it hard to figure out which side of the cockpit it is coming from, it takes a great deal of time to pick the bad relay out of a panel that has 30 or more relays. We have all been burned by the “touch” method; you could swear that you feel the relay actuating, but you pull the tiny screws holding the relay to the socket, remove the relay, only to find that was not the correct one… (click…click…click….)

Enter the Mag-Probe Since this tiny device senses magnetic fields, it will find your cycling relay in no time flat! Simply pass it along the row of relays and when it starts lighting up with the clicks you hear, you have found your cycling relay without dropping those tiny screws down into the abyss of the circuit breaker panel…. Now you can get right to work on finding out why that relay is cycling!

The Question you are probably thinking about right now is,  how much time does it take to conduct a typical test like this?  And how many of these tests do I do per week?  Then plug these numbers into the spreadsheet below to find out how much this time is costing your company in all of your facilities that do the same test using only a voltmeter. If you have a nightmare test in your industry that you solved using a Mag-Probe we would like to hear about it.

Mag-Probe Here to Help You

No matter what industry you work in

finding a clicking relay among a panel

of relays is the most difficult task you

will conduct when using a voltmeter.


Just Below is a Typical Scenario


Starting in the voltmeter column:  The first, second and fourth row will be duplicated in order to get an accurate calculation.

Ace Trouble Shooter Furie Electrician

Good Morning Bob,

Mag-Probe Excel Interactive Downtime WorksheetThank you for the Mag-Probes. This product is one of the most useful tools in my tool bag, being an electrician/instrument tech, your product saves vast amounts of time. I work in the oil and gas industry which is mostly Class 1 Div 1 locations.

With the junction boxes having anywhere from 20 to 100 bolts holding the covers in place which also weigh up to hundreds of pounds usually in very loud and hot areas the Mag-Probe makes trouble shooting solenoids and relays faster and much easier than opening all these boxes to use my volt meter.

Some boxes may take up to an hour to get open due to having to use hand tools to break the bolts loose and often there are bolt seized in place and in some places, we cannot use a power tool to open them then to close them we have to do that by hand as they are torqued to avoid damage to the boxes.

Then most of the time the solenoids are remote from the J-boxes they might not even be in the same room.   

Doing fire and gas systems we can check all the solenoids in a matter of minutes and there may be 50 solenoids on one suppression system instead of opening all the little junction boxes and using a voltmeter we can verify function just with the touch of the Mag-Probe.

I have used Mag-Probes for over 20 years now.  Like I said this is the handiest little tool to have in your tool bag.

Roger Begor went on to say in a phone conversation we had “There are much smaller valves we test frequently and are able to conduct tests right through the protective shields saving us a tremendous amount of time.”  

I saved time and money when I used mine last night! We heard a relay cycling on a rack and could not not determine which one it was. I grabbed the mag-probe and we found the culprit in a few seconds. Finding that relay lead us to a bad flap switch. We replaced the switch and were able to get up and running for the morning. Thank you Bob Bartol!!  Join Bob On LinkedIn

Mag-Probe Test Keeps Boeing 767 from Being Grounded Permanantly

Below are emails from Saemi explaining how they found the problem.

Date: September 4, 2015 at 5:27:16 AM MDT

Hi Bob

Oh yes.. Boeing 767 Been flying around.  Idle disagree problem was solved 19 Aug.  I’ve been waiting for the problem to appear again. But so far so good.  If this happens again I will aim for Boeing 767 Relay K207 with the Mag Probe  🙂 This was a very costly defect as many parts where replaced. With the right troubleshooting steps I’m sure the parts that were replacement could have been reduced. The hardest part trouble shooting this problem was it was an intermittent problem.. The air idle problem was on engine 2.  Relay K207 was loosing ground intermittently.  Without using the Mag-Probe this would be hard to detect.

Dear Bob

Like I promised before that I will send a statement on how the Mag Probe was useful shooting a B 767 “”” Boeing 767-300 / Relay Intermittent Defect. Engine 2.    The Mag-Probe was a big help to solve an intermittent problem with one of the relays that controls the engine Flight Idle & Approach Idle on a Boeing 767-300.  With the Mag-Probe it was possible to see the relay was loosing power intermittently, that helped us to determine the fault. It reduced trouble shooting time and a component change was made as a result of the trouble shooting.

Saemi / Aircraft Engineer.

Make no mistake here, there is no other product that we have found in the market place today that can lower downtime costs faster than a Mag-Probe.  Why?  Because the Mag-Probe requires no calibration, it’s ready to use right out of the box, and is the most versatile test instrument in it’s category. You hide a magnetic field.  What does this mean for your company?  It means it has the ability to work in every industry in the world that has a solenoid valve, relay or coil.   So not only can it be used in your industry, but can be cross used by your auto mechanics, elevator technicians, at all your oil and gas locations, shipping fleets,  manufacturing, aerospace applications, the list is endless.  See the bullet list below to get more operational application information about the Mag-Probe.

If all of your similar facilities that could be using the Mag-Probe are not using it then you could be losing a lot of money needlessly. Watch the video and see for yourself. Below is a Mag-Probe Interactive Downtime Spreadsheet so you can enter your own numbers and compute your Lost Potential Revenue.  This is Money you could be reinvesting in your business or putting in your pocket. (Computed Using a 52 week calendar year)

Don’t be mislead there are many companies that have tried to imitate the Mag-Probe but cannot. If you decide to purchase another cheaply made foreign product with a replaceable battery you will be let down because of many reasons.  We can talk more about these reasons in another post that will follow this one.  But for now here is a spreadsheet for you to input your own numbers after you do your homework.

Mag-Probe Interactive Downtime Spreadsheet

Mag-Probe Interactive Downtime Spreadsheet Below

Mag-Probe Interactive Downtime Spreadsheet

Mag-Probe Interactive Downtime Spreadsheet

The Mag-Probe Interactive Downtime Spreadsheet compares (the time it takes a Mag-Probe) to (the time it takes a voltmeter) to conduct the same (elimination) test when troubleshooting solenoid valves, relays, and coils. It computes the Lost Potential Revenue i.e. (the time difference between conducting a test using a Mag-Probe and the time it takes to conduct the same test using a Voltmeter) over a 52 week period – for one location.  It then multiplies the result by the total number of facilities entered into the spreadsheet that do the same test.  The result will be the revenue you could have earned if all of your facilities used Mag-Probes.

Since time is money then more profit could be realized if a plane got out of the hanger faster and back into service, or an elevator that was out of service transporting people  in a busy high rise business complex.  Or you might be loosing $1,000 + an hour at an oil pump station.  The same applies for food processing and manufacturing.  Some of our customers include Nuclear Power Plants across America. Imagine the downtime cost at a Nuclear Power Plant.  I imagine it would be Staggering!

One Elevator Maintenance Group Conducted a Survey in Canada and reported they realized a net profit increase of $10,000 per year in maximized productivity based off reduced troubleshooting time for each Mag-Probe placed into service.

What we have done here is to create an interactive downtime spreadsheet so you can enter your own numbers.  This post was initially intended to be directed toward companies that are already using the Mag-Probe, in only one or two facilities.  Once you plug in your numbers the spreadsheet will calculate the amount of lost potential revenue for all your facilities and give you the total for a 52 week period.  Just click the enter button after the last entry and the spreadsheet will do the calculation for you. The result will amaze you.

Here is HOW “The Spreadsheet Works”

Simply type your numbers into the Green Boxes of the Mag-Probe Interactive Spreadsheet.  For accuracy the 1st, 2nd and 4th green box numbers in the voltmeter column will automatically be duplicated in the red Mag-Probe column.  They will have to be the same number in order to get a correct downtime computation. The only numbers that will be different will be the “Time it Takes to Conduct the Same Test”  Please read the following 4 points before using the spreadsheet.

  1. Total Number of Facilities – You can enter the number of your facilities that make the same test.  The spreadsheet will then multiply the time it takes to make the test for a voltmeter and the time it takes when using a Mag-Probe by the number of tests made per week and convert it to the amount of money you are losing by not using Mag-Probes in all your facilities.
  2. Technicians Wage or Production Cost (per hour) – Here you will enter the technicians hourly wage (which will work for service oriented maintenance calls) or your production cost per hour for manufacturing plants, bottling plants, shipyards or anywhere solenoid valves, relays, or coils are used in the production process.  (Special Note: The dollar sign will appear automatically once you hit the enter key)
  3. Time It Takes To Conduct The Test (in minutes) – These are the only boxes that will have different entries (in these boxes you will be entering different times) you will enter the time it takes you to conduct a particular test using a Voltmeter and then enter the time it takes you to conduct the exact same test using a Bartol Mag-Probe in the Mag-Probe Column.  (Special Note: This entry must be entered in minutes)
  4. Lastly, is the Tests Conducted (per week) –  This will be how many tests you did with a voltmeter each week and now you are using a Mag-Probe instead to conduct the same test. This number should also be the same number so it will automatically be duplicated in the mag-Probe Column.  If you only conduct one of these tests per month or even 2 or 3 refer to the chart below.

.0625 = 1 Test Every Two Months

.25 = 1 Test Per Month

.50 = 2 Tests Per Month

.75 = 3 Tests Per Month

    1 = 4 Tests Per Month

So if you know the time it takes to do a particular elimination test with a voltmeter and you know the time it takes to do the same test using a Bartol Mag-Probe you can enter these numbers into the Mag-Probe Interactive Downtime Spreadsheet.   The spreadsheet will then compute how much money you could be saving by using the Mag-Probe in all of your facilities.    Or rather it computes your Lost Potential Revenue, money that you could be using somewhere else in your business..

The Bartol Mag-Probe is Very Simple, Portable and Easy to Operate.  There are many applications for the Mag-Probe and it has the ability to dramatically increase incremental profits by reducing troubleshooting Costs.

Typically CEO’s at large corporations conduct their business like the conductor of an orchestra.  A CEO truly is the master of observation and implementation and that is why he was selected to conduct the orchestra.  Just like the conductor of a great orchestra,  a Great CEO listens to his employees and vendors that continually give him updated information he can use in order to make decisions that make sense Lowering Downtime while raising the incremental profits is very important to a company in order to raise the bottom line.  So it stands too reason, if someone in the the orchestra came up with an idea to help the composition of an arrangement to become much better,  the conductor would take a closer look at the suggestion.  Once he determines this choice could dramatically raise the performance of the orchestra he decides, “Yes this will be a Good choice let’s do it.”  This is no different than a CEO seeking out best practices through input from employees and vendors in order to lower downtime and create a profitable choice.

So again the Mag-Probe is the best choice a CEO, President or Owner of any service or manufacturing company could make.  Why?   Because typically the return on your Mag-Probe investment will be one test.   The Mag-Probe is guaranteed to conduct 5,000 five second operations. So after the first test, you can begin recovering your investment.  NOT BAD SINCE YOU WILL HAVE 4,999 MORE TESTS AVAILABLE

Bob Bartol has spent his whole life working with electronics in almost every capacity and spent many hours in Physics classes. He currently holds 4 U.S. patents and has been making a living off one of the patents "The Bartol Mag-Probe" for over twenty years. Bartol Research's Mag-Probe now has a global reach and is dramatically reducing trouble shooting downtime anywhere a solenoid valve. relay, or contactor is used. F111 Air Force Projects - European Flight Competition January 1968 Bob attended electronics school in the Air Force. Upon graduation he was assigned to a fighter wing in Germany. During his assignment he prepared seven aircraft for European competition. The fighter wings aircraft won the competition. Bob then returned to the United States and taught advanced radar for two years. Two years later, he returned to Europe. During this assignment, Air Force headquarters Europe selected Bob to open a Precision Measuring Equipment Laboratory (P.M.E.L) in England. It was the first of its kind in the Air Force. Upon his return to the United States, Air Force headquarters assigned Bob to Air Force research command in Florida. This was strictly a scientific assignment for research and development. After three years he moved from Eglin AFB in Florida to Edwards Air Force Base in California where he had direct contact with the National Bureau of Standards and supported research and development aircraft. During this assignment, he designed a modification for the TF X fighter (F-111). This modification made possible an additional 9800 flying hours per year. The F111 was the first swing wing aircraft in history. General Dynamics completed the modification prior to acceptance by the U.S. Air Force. Modification of F111 Aircraft General Dynamics March 1968 As a result of increasing this flying time Bob Received an award from Edwards Air Force Base for Increasing flying time of the F111 by 9,800 hours per year. The Award was Presented by Colonel Grumbles to TSGT Bob Bartol on June 17, 1968
