How many times can the zero reset be used?
The zero reset can be used up to approximately 100,000 times. This is because the default setting specifies that every time the zero reset is used, the zero reset value must be stored in internal memory. Therefore, when even when power is interrupted, the zero reset value will revert to the previous status set by the zero reset function when the power is turned ON again.
If there is no need to save the zero reset value, you can use the zero reset an unlimited number of times by going to FUN mode and setting (ZRMEN) under (SPCL) to (OFF).
