Still have a question after reading this Fluke 902 FC review? Feel free to leave a comment below.
Fluke needs to get the basic HVAC clamp meter right before offering the wireless feature. There is no inrush, the resistance is way to low for measuring motor winding to ground, the audible continuity beeper is non existant, (I can’t confirm it exists, as I’ve never heard it), and most other meters also have a led light or backlight flash to confirm continuity in noisy environs.
It’s like Fluke doesn’t want to compete is this market, and just throw out a half baked meter.
Look at Fieldpiece, UEI, and Klein for real HVAC metera and you’ll quickly see the difference.
