6-5 Digital Zero Calibration
6-5-1 Digital Zero Calibration Method
It shall be executed when there is nothing on the load cell.
Range of zero calibration is 100% of max capacity. It is remembered even when the power is
turned off.
Push No.2 key while pushing
No.4 key.
Zero calibration is completed.
Zero calibration cannot be conducted under key lock status thus it shall be executed after
cancelling the key lock.
Zero calibration is not conducted on the hold.
When offset value is set at function, the value other than offset value shall be executed as zero.
Setting shall be conducted at function in order execute initial zero when turning on the power.
Zero calibration may not be conducted when there is mechanical interference or load cell
abnormality.
6-5-2 Zero Calibration Method by External Input
It shall be executed when nothing is on the load cell.
Relay contact point or contactless switch such as switch or open collector shall be used.
Signal shall be cut off after continuous external input of 10ms or longer.
Please take caution as zero is continuously executed when signal is continuously input not as a pulse.
Range of zero calibration is 100% max capacity. It is remembered even when power is turned off.
