fluctuating resistants reading megger met 1710

Done all of that, no point testing against known values because its not consistent. If I move the connectors it changes

If it’s not reading a known value consistently and you have replaced the leads them it needs to go for repair ...

So it’s the manufacturer or an independent repair shop

Where are you based as Englan is a bit vague

Zero leads, replace batteries, check leads, check battery connections. Don't leave meter in van overnight ( prevents damp getting into the meter). Other causes of fluctuating readings is usually attributed to either damp in the cables or newly plastered walls. I keep my old mft calibrated as a spare 'go to' if I have suspect readings and for use while my main meter is being calibrated. Mft's can be temperamental bit like the missus!
