Executing Zero Reset
When the zero reset function is used, the measured value can be reset to a reference
value of 0 when the ENT key is pressed or an external signal is input.
If zero reset has already been executed, that value will be overwritten. Execute zero
reset within the rated measurement distance. The settings are saved even if the power
is turned OFF (default).
Zero reset memory, p. 96
Linear Output
The measured value when zero reset is executed will be the center value in the linear output range.
When monitor focus is set, the measured value will be the center value between the two points set
for monitor focus.
Example
Before Zero Reset
1.2 mm
−0.4 mm
−0.8 mm
Zero reset executed
at -0.4 mm
After Zero Reset
1.0 mm
0.0 mm
−1.0 mm
If the following values are displayed after executing zero reset, then the measurement has probably
failed.
Example: 5.9999 or − 5.999
Correct the offset value.
A setting can be changed so that the zero reset is released when the power is turned OFF.
Saving Zero Reset Level, p. 96
1.
Place the reference sensing object in position.
2.
Set the mode switch to RUN.
3.
Press the ENT Key for more than one second
or input the zero reset signal from an external
device (for 800 ms max.).
The reference value will be registered and the zero reset
indicator will be lit. The tolerance for the registered refer-
ence value will be displayed on the main display.
