It seems that my TA189 30A Current clamp is very noisy. It is so noisy that it is basically unusable at the +/-100mA setting. The measured peak to peak noise is 248.1mA, and the measured True RMS is 11.06mA with nothing in the clamp. This is after zeroing. The Channel is set to 30A Current Clamp, 20 MHz Bandwidth Limit.
Is this normal or do I have a bad clamp?
Having problems ? let us know the details here
