9. DIGITAL ZERO (DZ)
The digital zero function sets a desired measurement point as zero and displays the
deviation from this zero point. When weighing a load, it can be used as the tare, etc.
While this function is used, the
DZ
LED turns on.
9.1. Operating by key
When the key is pressed, the display is set to zero and the DZ function is turned on.
If you want to turn the DZ function off, press the + keys.
* The operating procedure can be changed in the function mode (
Cf-11
).
Press the + keys or press and hold the key for more than 1 second,
turn on the DZ function.
When it is turned on, the display is set to zero.
9.2. Operating by I/O input
Whether the DZ function is ON or OFF depends on the operation of the zero terminal of
the I/O input.
When the zero terminal is on (connected to the COM terminal), the DZ function is turned
on and the display is set to zero.
You can disable the digital zero off in the function mode (
Cf-12
).
9.3. Zero tracking
Using the zero tracking function, the AD-4531B updates the zero point automatically by
sensing the zero point drift.
Zero tracking is available only when the digital zero function is turned on. Set the zero
tracking time (
Cf-08
) and zero tracking width (
Cf-09
) in the function mode.
* When the zero point is beyond the zero adjustment range, zero tracking is not performed.
* The zero point updated using the zero tracking function will not be saved in
non-volatile memory.
