(33) Zero calibration setting (nZro)
It is a function to let zero calibration complete in the state that maintained the present signal
output and analog output.
Hold down the enter switch on the front panel to allow [nZro] to blink, and press the enter
switch again to perform zero calibration. Operate the mode switch to cancel the calibration.
Zero point calibration cannot be performed by a zero calibration input signal (external signal).
* When recovered to the measurement mode, maintenance of
the signal output and the analog output are canceled, and the
concentration display is updated.
* Be sure to perform the above operation in an atmosphere
without ozone and in a state where zero gas is fed.
* Calibration values have been stored in nonvolatile memory even
after the power is turned off.
5.2.3 Check
mode
