6. Operation
6.1. General Function
6.1.1. Zero adjustment
Zero adjustment is a function to set the gross weight to zero. It is performed by
pressing the ZERO key or by a command from the CC-Link master station.
The zero adjustment range is set in
Calf05
(zero adjustment range) and is
expressed in percent of the weighing capacity with the calibration zero point as the
center.
Zero adjustment is disabled, even within the zero adjustment range, when the A/D
converter overflow occurs.
A ZERO error is output if zero adjustment is not performed.
The zero value is stored in the battery backup RAM and is maintained, even if the
power is disconnected.
Clearing the zero value is performed using the F key assigned to clear the zero
value. Alternately, apply power to the indicator while holding down the TARE key, or with
the indicator in the OFF mode, press and hold the TARE key and press the ON/OFF key,
to clear the zero value.

: Enables or disables zero adjustment when unstable.
z
Calf16
: Enables or disables power-ON zero (function to zero upon power-ON).
6.1.2. Zero tracking
Zero tracking is a function to track the weight drift around the zero point to maintain
zero.
The zero tracking time is set in
Calf06
(zero tracking time) and the zero tracking
band is set in
Calf07
(zero tracking band). When the weight drift is within the
specified ranges, zero tracking is performed automatically.
A ZERO error is not output even if zero tracking is not performed.
Functions related to zero tracking
z
Calf06
: Changes the zero tracking time. (0.0 to 5.0 seconds)
