Metrel instaltest giving strange readings when testing single phase voltage

[Bryan Smith]

Hi everyone, I have a metrel instaltest that, when testing single phase voltage always returns a reading of 540 V on L1 L2 L3. This suggests an internal fault that it automatically thinks it's testing three phase somehow. Has anyone else experienced similar faults with Metrel gear? Thanks

It's not a problem I have had or heard of

When was it last calibrated? Have you got a check box/card?
My 61557 started to give strange readings then decided it didn't want to work for me any more.

We had to retire all of our metrol test kit due to not being able to trust them. I would go for a megger or similar.
