As above I find myself in need of a service / calibration manual for a multi-meter clamp meter LEM Hemc LH630 which I believe is a fluke clone I could be wrong on this. The Unit generally works and is accurate on AC / DC when compared to my 6 digit bench meter. However I find that its not auto zeroing on DC amps and oddly the resistance measurement goes to -2.5 ohms when leads are shorted, while resistance measurement is generally accurate otherwise when you take this into consideration.
I may have put this in the wrong place, if I have some-one please move it to a more appropriate place thanking you in advance
