calibration so the “on Hold” message is not displayed even if the output
signal is held. However, “on Hold” message is displayed during the hold
extending time shown in Figure 3-10.
For both manual and auto calibration, if the calibration is cancelled
after the calibration gas has been directed to the analyzer, the hold
extending time will be performed.
