2.4.2 Functions
Display Functions:
Value Display; Displays values of the measured oxygen concentration, etc
Graph Display; Displays trends of measured oxygen concentration
Data Display; Displays various useful data for maintenance, such as cell
temperature, reference junction temperature, maximum/minimum
oxygen concentration, or the like.
Status Message; Indicates an alarm or error occurrence with flashing of the
corresponding icon. Indicates status such as warming-up,
calibrating, or the like by icon.
Alarm, Error Display; Displays alarms such as “Abnormal cell e.m.f.” when any
such status occurs.
Calibration functions:
Auto-Calibration; It calibrates automatically at specified intervals.
Semi-auto Calibration; Input calibration direction on the touch screen or contact,
then it calibrates automatically afterwards.
Manual Calibration; Calibration with opening/closing the valve of calibration
gas in operation interactively with an LCD touch screen.
Validation Function: Permits control room activation of zero, span or midpoint gas
concentrations without running an actual calibration.
Blowback Function:
Output through the contact in the set period and time. Auto/semi-auto
selectable.
