1.1 Attention Before Start
●Always use Earthed/Grounded Mains socket.
●Do not connect powerful electrical machines on the same mains plug.
●Disconnect mains connector before opening the enclosure.
●Recommended load cell cable cross section is 1 mm². f the cable length is too long, use multiple
wires for ±Excitation connections.
●f the sense inputs on the load cell connector are left empty, the device will display Err 3. Make sure
all the pins are connected.
●Shielded twisted-pair cables must be used for load cell and communication.
●For best accuracy, the device shall be powered on at least 30 minutes before adjustment.

2.2 Keypad
Zero key: Set the indication to zero. Zeroing can be established only if the gross weight
is within ±2% of the maximum capacity.
Tare In / Tare Out key: f the indicated value is positive and stable, it is saved as tare
and net weight is indicated. f there is already a tare device in operation, it is cancelled
and gross weight is indicated.
Print key: f the indicated value is positive and stable it is saved as a weighing result
and a print out is produced (if configured).
Star key: Call up the configuration menu. Please refer to the configuration section.
Function key: Activates and deactivates a configured function. For a complete
explanation refer to the related section of this manual.
Note: For an explanation of the function of the keys while editing numerical values please refer to the
