6 MAINTENANCE
The meter is not equipped with moving parts and/or mechanical parts subject to wear and therefore it
does not require any ordinary maintenance except for the periodic check of the correct closure of the cable
glands, the condition of the sealing gaskets of the covers and the replacement of the discharged battery.
The device (front panel and converter casing) can easily be cleaned with soft cloths and neutral detergents.
6.1 CABLE GLAND CLOSING AND GASKET CONDITION CHECK
Since the environmental characteristics where the meter is installed are not known in advance, it is not
possible to provide univocal indications on how often periodic checks on cable glands and gaskets should
be performed.
The operating experience of the user and the knowledge of the environmental characteristics of the
flowmeter installation location will allow the operator to decide how frequently regular controls must be
made.
Warning! Flowmeters that are positioned outdoors and/or in places/supports subject to vibrations can
loosen the cable glands over time, so they must be checked/controlled more frequently than flowmeters
that are installed in closed environments and/or protected from external stresses.
CHECKS
Perform periodical checks of the tightness of the cable glands and their condition.
On this occasion, check the condition of the seal in the cover.
Finally, check that all the electrical cables are correctly axed to the relative terminals, that they are
physically intact and that they do not show signs of deterioration.
6.2 BATTERY INSTALLATION/REPLACEMENT
The battery pack is usually SEPARATELY supplied, therefore, before the M10 is put into operation, the
battery pack must be inserted in its housing and connected to the instrument according to the instructions
provided in chapter 4.7.
NOTE: The operations described in chapter 4.7 are also valid for the replacement of the battery, which is
necessary to be performed when the status icon “
” indicates a low charge level on the M10 display.
NOTE: Under normal operating conditions, the battery life can last up to 10-15 years. Any changes to the
settings and programming of the converter (see paragraph 5.3) can aect the battery life.
