Temperature-Volume Corrector TC210

5.9 Maintenance

If the TC210 is used in the field subject to calibration regulations, the recalibration periods
must be observed.
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.

5.9.1 Battery replacement

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 TC210
under "System" submenu.
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 reduces
more quickly through more frequent measurement, reading out of the values and an
active display.
F
Battery replacement can be carried out without the presence of a calibration official,
because the housing itself is not sealed.
F
TC210 measurements (e.g. counter readings) may be lost due to careless proce-
dures. All the set parameters and, once daily, the date, time and counter readings
are also saved in an EEPROM. This means that these values are also not com-
pletely lost even in the event of a voltage failure.
F
Generally, replacement should only be carried out by ELSTER Service or by spe-
cially trained personnel.
