Web6 jul. 2016 · Digital and legacy analog clamp-on ammeters work well and are capable of measuring up to 200 A, which is adequate for most motor work. The basic procedure is to measure the start-up and running current for any motor while it’s connected to a load. Compare the reading to documented or nameplate specifications. Web15 jan. 2013 · I bought a mastech combo ac/dc volt-clamp amp meter back in '05 to check battery voltage and motor amp readings. Worked great, in '08 bought a new charger that has a watt meter. Used the watt meter a couple of times, but went back to the clamp meter. I just find it easier to check amps by clamping the jaw around one of the leads. …

WebAll you know is that the motor is probably running on either 12V or 24V. If the 12V batteries are connected in series then the motor probably operates on 24V. Current draw of the motor will change depending upon load. You can not directly infer the motor current from the battery capacity unless you did a complicated set of experiments. Web9 okt. 2024 · Note, that a 1 HP motor not fully loaded (good practice) will show current draw of less than 8 amps. What are starting amps?
