Leakage Mode Functions
Function
Comments
View most System Status Information
Displays the pressure readings from up to four
different sensors.
Display software version
Lists the software version number.
Switch Channel in the Main Display
Selects what to show in the main display. The
choices are channel 1, 2, 3, 4, or dual channel
display function 1 or 2.
Turn a Channel ON/OFF
Turns power to a sensor on or off, and turns the
sensor’s channel on or off. Only the channel
(not the sensor power) is turned off for
capacitance manometers.
Turn an Alarm ON/OFF
Enables/disables standard alarms A and B, and
optional alarms C and D.
Zero a Sensor/MFC
Sets the zero pressure point for a sensor.
Toggle the Zero-of-a-Sensor/MFC On and
Off
Toggles between undoing the zero, and then re-
instating the zero, once a sensor has been zeroed.
Span a Pirani Sensor to Atmosphere
Sets the upper pressure reading of a Pirani sensor
equal to 760 Torr or Atmosphere (Atm),
whichever is applicable.
Span a Sensor with a Reference
Spans the sensor of a selected channel to the
reading of another sensor.
Toggle the Span-of-a -Sensor On and Off
Toggles between undoing the span, and then re-
instating the span, once a sensor has been
spanned.
Set Lower and Upper Points for Analog
Set Point Calculations
Changes the analog set point by adjusting the
analog set point input voltage.
Command MFC Open/Close Overrides
Moves an MFC to full open or full close within
two seconds.
Cancel MFC Open/Close Overrides
Cancels an override that is in effect.
Start Hot Cathode Low/High Power
Degassing
Starts low power or high power degassing for a
hot cathode which is currently powered on.
Stop HC Degassing
Ends the degassing (low power or high power)
function currently underway.
