Klein Tools MM325 Digital Multimeter
Klein's MM325 is a manual-ranging meter sold at every hardware store, with DC and AC volts, resistance, continuity, diode test and a 10 A current range. The current range is the difference from the Fluke 101: you can measure the standby draw from a light or accessory, which is occasionally useful. It is rugged, comes with decent leads and a stand, and reads e-bike pack voltages in the 36–52 V range without fuss. Manual ranging means you pick the range yourself, which is one more thing to learn but also one less thing to go wrong. A sensible choice for the home toolbox.
Best for: General home and e-bike electrical checks · Riders who want an amps range · Hardware-store convenience
