PM600 Meters

[Andy_Hubert]

I have a customer here in the UK with a very old system (PMX1500) and a number of PM600 meters.

One of the PM600's has recently started to drop out of comms at random intervals, and it also appears to be resetting its energy count at the same time.

Has anyone else ever seen this issue??

Cheers

Andy

Andy:

The main issue that we have encountered with a PM600 class meter has been improper grounding of the power grounding terminal.  They have been more sensitive to grounding issues than other meters.  There are some New In Box PM600 meters on the gray market.  I may know where a few are buried.

Thanks,

Michael
