Apparently, there are two different models floating around Amazon (ASIN B0002SRIW8) that are packaged as Fluke RPM80 inductive probes (Fig 1). I received the model shown in Fig 1A which appears to be an All-Sun Model EA-100 that can be purchased from All-Sun for $16.99 (Amazon ASIN B015PDXBU). This review is for that model only. Other than “EA-100” and “Inductive Pickup”, there are no other markings on the probe identifying Fluke Corporation or All-Sun (Eastern Company, Zhangzhou City, China) as the manufacturer. I do not know who manufactures and the model number of the probe shown in Fig 1B.I was pleased with the easy clamping action with a bigger hole to fit spark plug wires of various sizes. The unit is lightweight and has very high quality 5-6 foot red and black polarized test leads to plug into a multi-meter capable of measuring frequency or rpm. The only longer-term issue I foresee is cracking the somewhat thin and brittle black plastic of the probe body. (-0.5 star)I tested the probe’s pickup ability on spark plug wire on an unloaded Briggs & Stratton 030253 Generator that’s governed to run at 3600 rpm. The arrow on the probe should point towards the spark plug (Fig 2). The oscilloscope waveform is shown in Fig 3. The spark firing delta-t was 16 milliseconds or 62.5 spark events per second (Hertz). I do not know why the spark plug signal levels alternate between 3.3 and 1.3 volts peak. Since Hertz (Hz) is per second and RPM is per minute, I understand you have to multiply Hertz by 60 to get spark signals per minute. This would be 3,750 RPM.To check my oscilloscope readings, I used my Crenova MS8233D multi-meter (Amazon ASIN B00KXX2OYY) connected to the RPM80 probe (Fig 4). The results are in fair agreement; however, how various multi-meters would process this spikey signal to determine volts AC is unknown.Overall, I was very pleased with the probe’s pickup ability and cleanliness of the spark plug signal for determining frequency and signal levels.However, I still remain confused as to the different models of this RPM80 probe sold in Fluke packaging by various sellers, including Amazon. Fluke’s ‘official’ website still pictures what appears to be All-Sun EA-100 model at the time of this review. (-0.5 stars)

Works as expected. I do not have the correct meter for this to read properly but I can get the same results from a calculation.

This adapter worked great for tuning the carburetor on my atv with no tachometer. I have a fluke 87-III, not the 78 or 88 the descreption says it requires. All you have to do is set the multimeter to vdc and it works just fine. I tested this on my car first just to make sure, and it matched the tach on the dash perfectly. Just remember, if you use it for a 2-stroke engine like i did, you have to divide the displayed rpm's by 2 for the actual rpm of the engine since the plug fires on every rotation.

This item works as advertised. I have been using it to time my motorcycle, tune my vintage car and troubleshoot my daily driver.
