(Default value)
Turn [OFF] zero reset memory if, as in the example below, the zero point is reset for
each measurement.
Example: When the step of the sensing object is measured
• If zero reset memory is [ON], the zero reset level data will be written in the Sensor Controller non-
volatile memory (EEPROM) at each zero reset. The EEPROM can be written a maximum of
1,000,000 times. Writing the zero reset level for each measurement can, therefore, use up the life
of the memory and lead to malfunctions.
• Even if zero reset memory is enabled, the zero reset level will be held also when it is saved. Zero
reset will continue after startup when these functions have been changed.
The zero reset level is saved to memory even if the power is turned OFF.
Zero reset is canceled when the power is turned OFF.
