14.1 General maintenance
14.1.1 myDatalogGauge 3G
l
Check myDatalogGauge 3G regularly for mechanical damage.
l
Clean the myDatalogGauge 3G with a soft, moist cloth. Use a mild cleaning agent, if necessary.
Important note:
Due to the electrostatic effects, the protective armour must not be rubbed with
cloths in the Ex zone.
14.1.2 BLE Gauge and pressure sensor
l
Check the BLE Gauge sensor module (incl. the pressure sensor) regularly for mechanical damage.
l
Check all cables for mechanical damage at regular intervals.
l
Clean the BLE Gauge sensor module (incl. the pressure sensor) with a soft, moist cloth. Use a mild
cleaning agent, if necessary.
Important note:
Due to the electrostatic effects, the BLE Gauge sensor module (incl. the pressure
sensor) must not be rubbed with cloths in the Ex zone.
14.2 Maintenance of the myDatalogGauge 3G
Important note:
Only the manufacturer is permitted to open the enclosure to carry out maintenance
work, which must also be completed strictly outside the Ex area.
The myDatalogGauge 3G itself does not require any cyclic maintenance work other than the actions listed in
chapter "General maintenance" on page 137 and replacement of the batteries after max. 5 years. In the event
of unfavourable environmental conditions (e.g. low temperatures), it may occur that the battery capacity is
depleted before this period of time has elapsed. The remaining days until the next time the batteries need to
be replaced are shown on the display of the myDatalogGauge 3G (see "Display" on page 76). The batteries
must only be replaced by the manufacturer (see "Contact information" on page 157) or a certified service
partner. The device must be returned in its original packaging for this purpose.
14.3 Maintenance of the BLE Gauge sensor module
Important note:
Only the manufacturer is permitted to open the enclosure to carry out maintenance
work, which must also be completed strictly outside the Ex area.
The capacity of the installed battery is designed for a max. service life of 5 years (depending on the
measurement cycle). In the event of unfavourable environmental conditions (e.g. low temperatures), it may
occur that the battery capacity is depleted before this period of time has elapsed. To replace the battery, the
BLE Gauge must be sent back to the manufacturer in the original packaging (see "Return" on page 48). The
