Semi-auto Calibration; Requires the ZR40H Automatic Calibration Unit. Input calibration
direction on the touchscreen or contact, then it calibrates
automatically afterwards.
Manual Calibration; Calibration with opening/closing the valve of calibration gas in
operation interactively with an LCD touchscreen.
Blow back Function:
Output through the contact in the set period and time. Auto/Semi_Auto selectable.
Maintenance Functions:
Can operate updated data settings in daily operation and checking. Display data settings,
calibration data settings, blow back data settings, current output loop check, input/output
contact check.
Setup Functions:
Initial settings suit for the plant conditions when installing the converter.
Equipment settings, current output data settings, alarm data settings, contact data
settings, other settings.
Self-diagnosis:
This function diagnoses conditions of the converter or the detector and indicates when
any abnormal condition occurs.
Password Functions:
Enter your password to operate the analyzer excepting data display.
Individual passwords can be set for maintenance and setup.
