Questions & Answers
Can this be used to test if coaxial cables and a wall phone jack have power running through them? I want to cover with a blank plate but make sure there’s no power first
will it measure down to 2 ohms
Yes, the Klein Tools Cat. No. MM325, Digital Multimeter, Manual-Ranging, 600V, can measure resistance down to 2 ohms using its 200-ohm range, which displays readings in 0.1-ohm increments.
Will this meter read inductance?
No. The Klein Tools Cat. No. MM325, 600-Volt Digital Multi-Meter, Manual-Ranging, does not measure inductance. It measures AC/DC voltage, DC current, and resistance, and tests batteries, diodes, and continuity.
Does it read micro farrads
Klein Tools Cat. No. MM325, Digital Multimeter, Manual-Ranging, 600V, does not measure capacitance in microfarads (µF). It measures AC/DC voltage, DC current, resistance, and can test batteries, diodes, and continuity.
What kind of battery
The Klein Tools Cat. No. MM325, Digital Multimeter, Manual-Ranging, 600V, is powered by two AAA batteries, which are included with the purchase.
Will this work with A/C & D/C power
The Klein Tools Cat. No. MM325, Digital Multimeter, Manual-Ranging, 600V, can be used to measure both AC and DC voltage. It also measures DC current, resistance, continuity, and performs diode testing.
Can it test the ground in an outlet
The Klein Tools Cat. No. MM325, Digital Multimeter, Manual-Ranging, 600V, can be used to help verify grounding by measuring voltage at an outlet, but it is not a dedicated receptacle tester and does not automatically indicate if the outlet is wired correctly. For that type of outlet wiring check, we recommend Klein Tools Cat. No. ET270, Auto-Ranging Digital Multi-Tester with Standard/GFCI Receptacle Tester, which can indicate whether the outlet is wired correctly.
Can this test to see if car battery is good
The Klein Tools Cat. No. MM325 Digital Multimeter, Manual-Ranging, 600V, can be used to measure the voltage of a car battery, which provides a general indication of its charge level.
