LOAD CELL CONNECTIONS
The cable of the load cell (or load cells) should not be channeled
with other cables, but has to follow its own path.
The instrument can be connected up to maximum 4 load cells of 350
ohm in parallel. The supply voltage of the load cells is 4 Vdc and is
protected by temporary short circuit.
The measuring range of the instrument involves the use of load cells
with a sensitivity of up to 3.9 mV/V.
The cable of the load cells must be connected to terminals 2-7 of
the 7-pin removable terminal board. In the case of 4-wire load cell
cable, jump terminals 2 with 5 and 3 with 4.
Connect the cell cable shield to the terminal 1.
In the case of the usage of two or more load cells, use special jun-

SERIAL COMMUNICATION
RS232:
The RS232 serial port is always present and can handle several
protocols.
To achieve the serial connection use a suitable shielded cable and
make sure to ground the screen at one of the two ends: to pin 13,
if attached on the side of the instrument, to the ground, if connected
on the other side.

The cable must not be channeled with power cables, maximum length
of 15 meters (EIA RS-232-C).
