AUXILIARY FUNCTIONS
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. The settings are
saved even if the power is turned OFF (default).
This memory setting can be changed so that the zero reset settings are not saved
when the power is turned OFF.
Zero reset memory p.120
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:
The minimum display value is -19999, and the maximum display value is 59999. If the measured
value is below the minimum value after execution of zero reset, "-19999" will be displayed. "59999"
will be displayed if the measured value is above the maximum value.
Zero reset can be executed only if the measured value is within ±10% of the rated measuring range.
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 reference value will be
displayed on the main display.
