Fluke

Fluke 101 Basic Digital Multimeter

The Fluke 101 is the small, pocket-sized Fluke: DC and AC volts, resistance, continuity and capacitance, with no current measurement. For e-bike diagnosis that is almost everything you need — checking pack voltage at the discharge port, charger output at the plug, and continuity on brake cutoff wires. The reason to buy Fluke over a cheaper meter is trust: the readings are accurate and the meter is built to survive a drop. Limits: no current ranges, and it is not auto-ranging on every function. Measure only at exposed connectors and ports; never open a battery pack.

Best for: Checking battery and charger voltage · Continuity tests on cutoff switches and sensors · Riders who want a reliable meter for years
