Meters must only be repaired by an authorised service and repair centre
(or manufacturer).
The following procedure should be adopted if a meter repair is necessary:
1.
If the meter is installed, remove the meter as described in section 4.6
"Uninstallation" and fit a substitute meter.
2.
Describe the error found as exactly as possible and state the name
and telephone number of the person responsible in case of inquiries.
3.
Pack the meter to ensure it can suffer no further damage during
transport. Preferably use the original packing if available. Do not
enclose any loose components.
4.
Send the meter to the responsible service and repair centre.
