Thank you both for all your help.I did come across the manual showing the larger number of display fields, but didn't consider it was necessarily correct for the ZMD120ASer53 model.
I noticed there is a meter selling on eBay with a similar, but different ('Ser' is 'Ptr') model no here:
interestingly the seller pastes a link to the manual in his listing, the same as the one in my post #4 !

Subject: RE: ZMD120ASer53 Error code
Dear Andrew,
I have tracked down the error code that you are requesting assistance on.
Details of the error can be seen in the screen shot below.
![[ElectriciansForums.net] L+G 3ph Meter Error Codes](https://electricians.s3.eu-west-1.amazonaws.com/data/attachments/71/71579-9d2ec1a159ddf628b6a804b4e7003ea8.jpg "[ElectriciansForums.net] L+G 3ph Meter Error Codes")
The error code reflects to a measuring system error, and as such it is recommended that the meter be replaced.
The meter that you make reference to, was made end-of-life a number of years ago, but your energy supplier should have a suitable replacement meter.
You should contact your energy supplier with a request for the meter to be replaced.
Kind regards,
Scott
