If you don’t know anything about the original clamp, I suggest you not to play with some random clamp. You risk to damage your meter.
Original clamp can have current output or voltage output.
And any turn ratio.
Hello,
It sounds like the smaller clamp might not be compatible with the DSB28. The DSB28 typically uses a 30A/1V clamp. Ensure the smaller clamp is rated similarly and properly calibrated. If issues persist, consider contacting the manufacturer for support. Official Website
