Gross weight (tare + known weight) must not to exceed load cell end scale, to avoid
serious damage to the cell.
1) Power off the module before configuring it by Dip-Switches to avoid serious damage due to
electrostatic discharges.
2) Switch the Dip-Switches SW2-
4 to “ON” and SW2-5 to “OFF”. In this way, factory calibration
using calibration button (or digital input). It is possible to acquire tare value by digital input or
calibration button.
3) Switch the Dip-Switch SW2-
1 to “OFF”. In this way, calibration button for digital input (used
during calibration procedure) is enabled and it is possible to acquire tare value.
4) Switch the Dip-Switches SW2-2 and SW2-3 as shown in Dip-Switches table, to select one of
the possible modalities of analog output.
5) Switch the Dip-Switches SW2-6, SW2-7, SW2-8 to choose the load cell sensitivity (see Dip-
Switch table)
6) Power on the module
7) Put the tare on the load cell
8) Keep pushed the calibration button (or in alternative, only for Z-SG model, use digital input)
until LED ERR is “ON”
The Z-SG / Z-SG-L module has acquired tare value: this value is saved in EEPROM
(keep saved when the module is power off).
9) Power off the module
10) Switch the Dip-Switches SW2-
4 to “OFF” and SW2-5 to “OFF”. In this way, Z-SG / Z-SG-L
module is calibrated.
11) Power on the module
When calibration procedure is ended, it is possible to calibrate the module by the
digital input (only Z-SG model) or by calibration button (after switching SW2-
1 to “OFF”: digital
input is enabled). If a digital signal commutation (from “0” to “1”) occurs (through screw
terminals 1-6), a tare value is saved in RAM memory. This value is erased if the module is
power off or when a new digital signal commutation (from “0” to “1”) occurs (through screw
terminals 1-6).
If the module is power off during this procedure, calibration setting is lost. Restart the
calibration procedure from the first point.
Analog output end scale is related to load cell end scale, with the following equation:
Real end scale = Load cell end scale
– tare
