6-2-4. Digital zero clear
This function clears the value set to Digital Zero. Performing this function while
is in reverse-display (red), the Digital Zero value is cleared and goes
off.
Operation
Enter two numbers in the PASS WORD field: 1269, and then 1111
6-2-5. Zero tracking (ZT)
This function is used to correct/compensate slow zero-point drift or small zero-point
shift caused by residual materials such as mud, dirt, and snow.
[ZERO TRACKING (PERIOD)] specifies the Zero-tracking period, and [ZERO
TRACKING (RANGE)] specifies the Zero-tracking width.
Like Digital Zero, performing Zero-tracking while the gross weight exceeds the value
specified by [DZ REGULATION VALUE] gives rise to an alarm (
is displayed
in red reverse mode).

・
Zero tracking is the function to reset gross weight to zero automatically when
the state remaining the zero point drift within the zero tracking range
continues more than set period.
・ Zero tracking period must be set between 0.1 ~ 9.9 second and its range must
be set between 1 ~ 99 using 1/4 resolution interval of weight display.
For instance, 02 corresponds to 0.5 and 12 corresponds to 3 of weight display.
Zero tracking range is not proportional to the Minimum scale division
regardless of the setting state of Minimum scale division.
Zero tracking does not work if you set the period to 0.0 sec. and range to 00.
