1.3 Putting into operation
For startup, connect the terminal to an analog METTLER TOLEDO weighing platform
(see installation instructions METTLER TOLEDO Terminals IND4.. or call METTLER
TOLEDO Service).
1.3.1 Connecting the power supply
CAUTION!
Before connecting the scale to the mains, check whether the voltage value printed on
the rating plate corresponds with the local mains voltage.
▲ Never connect the device if the voltage value printed on the rating plate is different
to the local mains voltage.
➜ Plug the mains plug into the socket.
After connection, the device performs a self-test. When the zero display appears,
the device is ready to weigh.
➜ Calibrate the device in order to obtain the greatest possible precision, see
Section 3.3.1.
Note Partially certified scales (scales with first-level certification) must be certified by an
authorised body or by the METTLER TOLEDO Service.
➜ Call METTLER TOLEDO Service.
Note The battery’s charging capacity can be reduced under continuous mains operation.
➜ To maintain the charging capacity, after a maximum of 4 weeks discharge the bat-
tery completely before recharging it.
Terminals with AccuPac can work independently from the mains for approximately
30 hours in normal operation. A prerequisite for this is that the background lighting
is switched off and that no peripheral devices are connected.
The battery symbol indicates the present charging level of the battery. 1 segment corresponds to approx. 25 % capacity. When the symbol flashes the battery must be
charged (min. 4 hours). The charging period is extended if work is continued during
charging. The battery is protected against overcharging.
