CAUTION
• The flow time setting screen will only display the currently used Ch.
• The replacement time is the extended time to hold the output signal after the calibration is
completed. It is extended only when the hold setting is On. The replacement time set here is
also the hold extension time during manual calibration.
• Flow time setting should be long enough to allow the concentration value to stabilize.
• When a mixed gas containing multiple components is used as the calibration gas, the flow
time setting can be set to 5 seconds, the shortest possible time, because the continuous
calibration of those components eliminates the need for a second and subsequent flow time
setting. (The assignment of components to Ch is fixed and cannot be changed.)

5 to 900 seconds (default: 180 seconds)
CAUTION
• When auto-calibration starts, the measurement screen is automatically displayed.
• After the power is turned off (including power failure, etc.) and then turned on again, the next
automatic calibration is performed at the time set for the start time, and then at intervals of
cycles.
• Regardless of whether auto-calibration is On or Off, auto-calibration can be performed from
the screen or by remote start.
