Operating temperature: 0℃ --50℃ , < 80% RH Storage Temperature: -20℃ -- 60℃, < 85% RH Max Conductor Size: 30mm Max Jaw Opening: 25mm
Operating Instruction
1. The input impedance of ac Voltage range of the digital multimeter to be used with the Current Probe must be ≥ 1MΩ, and the multimeter’s ac Voltage measurement range to be used must be ≤ 2V ac. 2. Connect the output plugs of Current Probe to the ac voltage input terminals of the multimeter. 3. Set the rotary switch of the multimeter to the desired ac voltage measurement range position, make sure that the selected range is not higher 2V ac for accurate measurement. 4. Press the trigger and clamp the jaws around the conductor to be measured. Release the trigger slowly. Note: 1. Clamp only on conductor. 2. The conductor should be in the center of the jaws and should be perpendicular to the Current Probe. 5. Read the voltage reading of the multimeter. Then calculate the current of the conductor by using the formula: I= Reading / 1mV/ A (In this formula, I is the current of the conductor, Reading the voltage reading of the multimeter.)

I couldn't get good readings with my multimeter. I think I did everything per the instructions but I've been known to be wrong.

Does not work. Tested with a Fluke and Amprobe multimeter. Different current clamps worked fine. Had mud all over clamps, appears to be a return.

Doesn’t work at all. Tried it on a Fluke, it’s always 0.1 regardless of what I measure. I am using it properly, it’s just broken. Don’t waste your money.

It does the job, but it's not a precision instrument. Despite posted answers to the contrary, this is just a passive coil - no battery, no active circuitry. The specs that come with it specify a frequency range of 50-60 Hz, which is fine if you're just measuring power line current. Don't expect to make precise measures. The noise floor (measured with a Siglent SDS1204X-E scope) with zero current through the claw was was about 0.7 mV RMS, which corresponds to 0.7 Amps RMS current. It was high frequency noise, but I didn't investigate carefully - it may have been related to ambient RF fields picked up by the coil.

I have several clamp meters including a Fluke, and these tested to read the same value. They don't have all the features of a nice meter, but they get the job done for a lot less.

For use with nominal household currents of 10-15A make sure your measurement device can read 10-15mVAC accurately. Best with AC uV meter or meter with 30mVAC full range....accurate and stable readings.

I was pleasantly surprised. I bought three for a data logger and they performed better than my more expensive 200A clamps. There may be more of them in my future.
