a) While NR is on, if a measured leak rate exceeds the limit but within the NR limit, NR process starts
automatically. In the NR process, the DET stage is iterated a preset number of times.
b) When the tester enters NR process, a timer extension signal is transmitted from external I/O.
c) If the cycle timeout limit program is used by the external controller, use this signal to cancel it.
d) If the Master-Preset feature is on, Master-Preset compensation is not carried out during the noise
reduction process.
e) Leak test ends, when Go judgement is made.
f) The iteration number of DET can be set from 1 to 9. Setting the iteration to 0 disables the NR.

key several times until
P-5

Press the ENTER key for 1 second or longer.
rto
will be displayed on the LO leak limit indicator, and
10
will be displayed on the HI leak limit indicator. The displayed value for the NR limits is the ratio of
HI and LO limits to be added. If the displayed value is
10
, the NR limits are HI and LO limits plus 10%.
Example:
If HI is 100 and LO is -50, HH is 110 and LL is -55.
4) Values can be set from 10 to 90% by increments of 10%. Set the value using
