1. START UP OF THE INSTRUMENT
For a correct start up of the instrument it is necessary to carry out
the following operations:
- set up or check the electrical connections (see paragraph 2)
- set the weighing rate (see paragraphs 3 and 4)
- calibrate the weights (see paragraph 5)
1316-MPT020M03 - Rev.1
2. ELECTRICAL CONNECTIONS
The instrument must be connected according to the indications in
the following table:

Relè outputs
In the case where the apparatus uses more than one load cell, the
cells must be wired to a specific junction box (ADOS model 1308),
and the output must be connected to the terminals of T020E.
The use of shielded cable for the wiring of the load cells, the
analog output signal lines and the serial lines is highly
recommended.
