What range were you using it on - Auto LZ or AC voltage? Apparently, the auto range is a low impedance input (doesn't say how low), so that might trip the RCD on its own - it only needs 30mA. A normal electronic multimeter has 20kOhms or more input impedance, so would only give you 12mA or so. Also, you don't know whether any other equipment on the supply is also leaking curent.
not set it on continuity by mistake? that would explain itThanks crink, must have been that! I'll check it out tomorrow, good to know how to actually use this meter.
Stanni my old meter was digital and I was just tracing wires for new controls.
Found it - in the manual. 3k on auto, so 80mA. Enought to trip RCD.
