For meters with software ≤K75 or ≤K52:
If the so-called register test (meter constant or gear transmission error
test) is not carried out at a constant load point, but with a constant
injected amount of energy, a test time of 15 minutes is recommended
(minimum 10 minutes).
With the aid of a laptop computer or a suitable PDA together with a flag
probe and Landis+Gyr-specific software, it is possible to amend some of
the factory configured options of the meter. However, it is beyond the
scope of this manual to describe the procedure in any further detail.
Landis+Gyr Metering sales team would be happy to discuss specific
requirements, if they arise.
If the LCD window is illegible or the data readout does not function, the
following points should be checked.

Is mains voltage present?

Are the preliminary fuses intact?

Has the minimum or maximum recommended ambient temperature
been exceeded?

Is the LCD window clear of all debris? – Not misted over, painted
over or soiled in any way.
If none of the above are causing the fault, the meter should be
disconnected as described in section 7.4, replaced if required as
detailed in section 5, and returned to Landis+Gyr as described in section
7.5.
