Operation

3.1

Basic Operation

The instrument must be powered with stabilized voltage at 12 VDC or 24 VDC supplied from an AC/DC external
charger (not included) which should be connected to appropriately rated AC main voltage.
To power the instrument, connect the two power supply cables to the appropriate terminal board
page 3) on the side or the back of the instrument.
3.1.1

Turn on the Instrument

Press and hold until the instrument turns on, then release. The instrument executes a start up procedure and
C
displays the installed software version.
An auto zero function zeros the instrument at startup if the weight detected on the scale is ± 10% of the capacity. If
the weight is not within this tolerance the instrument displays the current weight.
The auto zero function at start-up can be disabled in the setup mode.

Momentarily press while the version number displays to view the following settings:
•  –  is the software release and  is the sub release
•  – optional board required
•  –  indicates the type of instrument,  indicates the software version
•  – the installed software version
•  – the name of the installed software
•  – capacity and division of channel 1
•  – displayed together with the gravitational acceleration value of the area of use
The instrument then executes a self-check.

Standby

Press until  displays. The LED at the left of the display remains on.

Power Off the Instrument

Remove the power supply.
3.1.4

Zero

Press to zero a gross weight within ± 2% of the total capacity. Weight value displays as 0 and the relative
annunciators illuminate.
3.1.5

Tare

Semiautomatic Tare
Press to tare the weight value on the scale.  displays momentarily and then 0 (net weight). The relative
annunciators illuminate.
Manual Tare
Press for a few seconds.  displays and then . Enter the desired tare value using the following keys:
• decreases the blinking digit
• increases the blinking digit
• selects the digit to be modified (moves left to right, selected digit blinks)
• momentary press zeros the present value, long press returns to the weigh mode without saving changes
C
• confirms the entered tare value
The tare value is subtracted from the weight on the scale and the relative annunciators illuminate.
Note
The entered tare will be rounded off to the nearest division.
