Adjusts the Ion source parameters to cause a maximum response to helium,
then adjusts the gain so that the current helium signal is the same as most
recently input using INIT-STDLEAK. Success is indicated by a yes response to
?CALOK<CR>. With PARALLEL ENABLE asserted, the response is cant.
Causes range limiting to cease operation. No parameters.
Causes the auto-sequencer to cease operation. No parameters.
Causes range limiting to begin operation. No parameters.
Causes the auto-sequencer to begin operation. No parameters.
Adjusts the variable focus Ion Source parameter to cause a maximum response
to helium. With PARALLEL ENABLE asserted, the response is cant.
Causes the leak detector to close most valves and enter the HOLD state.
No parameters.
Causes the leak detector to begin a roughing and testing sequence.
No parameters.
Sets the current system thermocouple reading to represent atmospheric
pressure. Success is indicated by the normal ok response.
Sets the current system thermocouple reading to represent a pressure that is
too low for a thermocouple to read. Success is indicated by the normal ok
response.
Sets the current test port thermocouple reading to represent atmospheric
pressure. Success is indicated by the normal ok response.
Sets the current test port thermocouple reading to represent a pressure that is
too low for a thermocouple to read. Success is indicated by the normal ok
response.
Adjusts Ion voltage to cause a maximum response to helium. With PARALLEL
ENABLE asserted, the response is cant.
Causes the leak detector to vent the test port to atmosphere. No parameters.
Sets the current leak rate measurement to be 0.00 atm cc/sec. Success is
indicated by the normal ok response. With the PARALLEL ENABLE asserted,
the response is cant.
