Convection Gauge Board
The Convection card operates two Thermocouple/Convection gauges and allows you to
calibrate:
❑ To the actual atmospheric pressure value,
❑ To vacuum pressure,
❑ and select calibration for air or argon.
Calibration is Agilent's Smart Cal that determines whether a CAL command is for vacuum or
atmosphere. Remote control of calibration and analog output is standard. Each channel has
its own 9-pin Dsub connector.
