2) Zero calibration timing chart exhibiting interval time
Figure- 11 Interval time timing chart
3) Timing chart exhibiting the case where manual operation is performed or zero calibration
input signal (external signal) is received
Note: If 0 minute is selected as the interval time, zero point calibration is performed only by
the enter switch operation and by zero input signals. Zero point calibration by internal
timer does not work.
In addition, if the purge time setting is set to 0 second, the zero calibration does not
work.

(3) Auto zero calibration (Auto zero)
Zero calibration is performed sequentially at intervals with the internally set auto zero interval
time regarded as one cycle.
The measurement period can be arbitrarily set by “auto zero interval setting” between 10 to 60
seconds (in increment of 1 second).
See “5.2.2 Setting mode, (25) Auto zero interval setting” for details.
* This does not accept enter switch operation and the zero calibration input signal (external
signal, command input).
* Zero calibration is performed automatically when the power is turned on.
