5.4 Maintenance
Apart from battery replacement the DL210 operates largely without needing maintenance.
Notice should be taken, where applicable, of the recalibration periods if the DL210 is used
in applications subject to official calibration.
When cleaning the housing becomes necessary, no aggressive cleanser (e.g. acetone,
petroleum spirit, etc.) should be used, because this may attack the housing. A damp cloth
with a soapy solution or similar is quite sufficient.
5.4.1 Battery replacement (basic unit)
During operation a check must be made from time to time of whether the battery needs to
be replaced. A display of the remaining battery service life is provided for this in the DL210
under the list "Service".
F
With the specified standard operating mode (see Chapter: B-2), operation is still
possible until as shown in the display. The remaining battery service life, of course,
reduces more quickly through more frequent measurement, reading out of the
values and active display.
F
Battery replacement can be carried out without the presence of a calibration official,
because the housing itself is not sealed.
F
Measurements (e.g. all load profiles) may be lost due to careless procedures. All set
parameters as well as, once daily, the date, time and meter readings are
additionally backed-up in an EEPROM, so that these values are not completely lost
even after a power failure.
F
Generally, replacement should only be carried out by the Service Department of
Elster-Instromet or by specially trained personnel.
5.4.1.1 Carrying out battery replacement
F
So that no data is lost, a manual backup must be carried out under "Service" –
"Save" (Save, address: 1:131).
The date, time and all counter readings are then
saved in a non-volatile memory.
(1) Open up the front cover with the electronics and swivel downwards. The battery is now
accessible on the CPU board.
(2) Check whether the size and identification number of the new battery match those on
calibration cover plate for the fitted device battery. Normally, the device battery has a
black connecting cable.
