How To Use The Delta Relative Function On The Fluke 87V Multimeter

bit.ly/2Le2Elz
In this video, learn how to use the delta (relative) function on the Fluke 87V.
When you have a set of test leads, there will always be a certain amount of resistance, resulting in skewed test measurements. With the Fluke 87V delta (relative) function, the digital multimeter will dynamically subtract out the resistance from your measurements for true, accurate readings. The delta (relative) function is also useful when you want to trend a voltage drop between the source and the load. A neat feature with the Fluke 87V digital multimeter is the delta (relative) function can be combined with other multimeter functions to troubleshoot more complex problems.
The Fluke 87V Industrial Multimeter provides the resolution and accuracy to efficiently troubleshoot motor drives, plant automation, power distribution, and electromechanical equipment even in loud, high energy, and high altitude locations. A low pass filter supports accurate frequency measurements on VFDs and captures intermittents as fast 250 µS.

Nice video. It was informative and answered a few questions I had about this function. Thank you...

Dude, thank you so much for this. I found a beautiful Fluke 27/FM from October 89 and it’s my bench meter. It has this function and i was always confused what it was.

Thank you for the explanation, I also have trouble with dB's on my old analog. I still don't understand how 440hz at 350mv can be -0.8db.
Anyway thanks for the Rel explanation
Best regards Randy

Ok so I'm not understanding how to read the negative voltage. How do I get there.

Hi Torrence - The negative voltage reading would happen in this example if after hitting the relative button and zeroing out the voltage, the next measurement could be the drop of voltage at the motor.

1. Press "min max" button to show PEAK values (instead of the default RMS).
2. The button below it (beep on/off) has a second function to scroll through peak/min/max/average(?) display. Press until display shows "MIN". This is your measured minimum (trough) value of the waveforms.
3. Press "REL"(ative delta) button to zero the display at this value.
If you've worked the tare function of a weighing scale, then it's eerily similar.
