Zero calibration
Register the zero point with the sensor unloaded. Also, if there is any initial load, such as a jig, for
measurements, the zero point can be registered with the initial load applied, but the signal input
range needs to be considered as the initial load is subtracted from it.
In addition, there is a way of considering the initial load by using the digital offset. See "

Digital
offset (This step may be omitted if there is no change.)" on page 30.

By performing zero calibration, the setting value of zero calibration becomes the sensor output
value (V) of the time when it was executed. The load with which zero calibration was performed
can be confirmed. However, it stays unchanged when an error occurs.
◇
Zero calibration setting method
1.
Select setting mode 4.
Press
→
three
times.
2.
Set "Zero calibration."
Press
twice.
⇒
"Zero calibration" is displayed.
Enter a setting value input state with
, and the
entire setting value blinks. (Initial value: 0.000)
Unload the sensor, check the current load value on the
sub display (angle display side), and press
.
3.
Zero calibration is executed.
A message as shown on the right-hand side is displayed.
If zero calibration is not executed normally, the alarm
sounds and an error is displayed.
4.
Go back to the setting item select state.
If zero calibration is executed normally, you will go back
to the setting item select state, and the output (V) of the
time when it was performed will appear.
The example shows that zero calibration was performed at
0.017V.
5.
Press
twice to go back to the indicated value display.
