Parameter
Turns the Reject Set Point ON. Where x is a number from 1 to 4 or the letter A.
Turns the Range Stop function ON.
Turns the auto sequencer function ON.
Turns the split flow function ON.
Turns audio ON.
Sets the External Calibrated Leak (in test port) as the leak for use during calibration.
Adds 1 to the Manual Ranging leak rate exponent (making it less negative).
Success is indicated by the normal ok response. Does nothing in
auto-ranging mode. Does nothing upon reaching the least sensitive range.
Sets the Internal Calibrated Leak as the leak to be used during calibration.
Causes the leak detector to close most valves and enter the Hold state.
Turns the Manual Ranging Mode ON. Success is indicated by the normal ok response.
Turns the HIGH PRESSURE TEST function OFF.
Causes the leak detector to begin a roughing on the test port only.
Turns the HIGH PRESSURE TEST mode ON.
Turns Read Std Leak ON/OFF. Verifies calibration by exposing internal cal leak to the
system.
Sets the current test port thermocouple reading to represent atmospheric pressure when
the test port is exposed to atmosphere. Success is indicated by the normal ok response.
Sets the current test port thermocouple reading to represent a ZERO pressure reading when
the test port pressure is less than 1.0E-04 Torr. Success is indicated by the normal ok
response.
Adjusts the ion source voltage to cause a maximum response to helium.
Causes the leak detector to isolate and vent the test port to the atmosphere.
Unlocks the system so that all RS-232 commands are accessible.
Sets the current leak rate measurement to be 0.0 atm cc/sec in the most sensitive range.
