Hi, I recently bought one unit of DROK®AC 100-300V 100A Digital Voltage Current Multimeter for testing. it works great but the readings are a bit below the ones on my calibrated current clamp. Is there a potentiometer in your amp reader to calibrate the gain? it would be great if it was possible.
Would adding a longer cable affect the reading much?
Are bigger thoroids available too?
Are there any products similar to DROK®AC 100-300V 100A but for AC100-300V-10A?
Thanks,
Alberto

Hello amartin,
Thank you for writing in.
There are two calibrating potentiomentes inside one for ampere calibration and the other for voltage calibration, please check the following image:

If you extend the cable, it will affect the accuracy of the current reading.
So sorry that we do not have a AC meter for AC100-300V-10A.
Beg your understanding and hope this can help you.
Best regards
