By setting an output hold to ON, the output signal of each channel is

held during the calibration (manual calibration and auto calibration) plus
the gas flow time as shown in Figures 3-10 through 3-12. Refer to Section
3.5.4, Setting of Auto Calibration for a description of the gas flow time.
Regardless of Hold ON/OFF setting, an output signal can always be held
via an external input.
