■Near zero

By this function, it is detected that the indicated value is near zero.
Near-zero ON: | indicated value | ≦ near zero set value
Near-zero OFF: | indicated value |＞ near zero set value
Setting range: 00000 - 99999
Near-zero ON/OFF is closely related to the SI/F Print Out (stable) and Comparison timing.
For details, see the sections "SI/F Print Out" on page 40 and "Comparison timing" on page
43.

■Comparison timing

Set the operating condition of HI-LO limit comparison. Select the condition from the following.
ALL: HI-LO limit comparison is performed continuously.
MD: HI-LO limit comparison is performed when the indicated value is stable.
Set the stable parameters by the stable operation.
NZ: HI-LO limit comparison is performed when the indicated value is not near zero.
Set the near zero parameters by the near zero operation.
MD+NZ: HI-LO limit comparison is performed when the indicated value is stable and not near zero.
HOLD: HI-LO limit comparison is performed when the indicated value is held.
