2.4 1HLC module calibration

Module calibration allows the subsequently measured values to be more precise. The registers and
connections in the calibration steps have already been converted by step 2 【Modbus Master Table】
in section 2.3 and the detailed corresponding registers are described in this section.

2.4.1 Zero-point calibration

Confirm that the tray or tank scale is empty and execute zero-point calibration input (X0 from 0 to 1); if
successful, the display value register DR500 (Modbus register 402307) will be zero. If not, confirm
whether the zero-point calibration operation is correct. Subsequently, set the status of X0 of zero-point
calibration back to 0 or else the display value will remain at 0 when measuring.

2.4.2 Full-span calibration

Place object of known weight (standardized weight) on the tray or tank scale and input the weight of
the object of known weight to the SPAN calibration weight register DR504 (Modbus register 402567);
after the displayed value is stable, execute SPAN calibration input (X1 from 0 to 1). The display value
register DR500 (Modbus register 402307) will be the same as DR504 (Modbus register 402567).
Subsequently, set X1 from 1 to 0 and remove the object of known weight (standardized weight);
measurements of objects may then begin.
Note: if register DR504 (Modbus register 402567) is zero then the display value register DR500
(Modbus register 402307) will remain zero when measuring weights.

2.4.3 Weight measuring

Place object on the tray and the display value register DR500 (Modbus register 402307) will display
the weight of the object according to the standard of the known weight in full-span calibration.
