Queries the status of the MS lock feature; either on or off appears.
Table A-3 Spectrometer Operating Parameters
Sets the exponent leak range for Manual mode. Preceded by a
two-character number Acceptable values are 0 through -10.
Sets the ion value of the ion source. Preceded by a three-digit number of
volts, in the range 200 to 350.
Sets the Range Stop exponent. Preceded by two or three characters -XX or
-X.
Table A-4 Leak Detection Actions
Initiates auto-ranging mode. Success is indicated by the normal ok
response.
Initiates a Full or Fast calibration depending on system settings. The CPU
software tunes, then adjusts the gain so that the current helium signal
causes the current leak rate measurement to be the same as the most
recently input using INIT-STDLEAK. If the gain is 2.9 or higher, a normal
calibration is performed. Success is indicated by the normal ok response.
Subtracts 1 from the Manual Ranging leak rate exponent (making it more
negative). Success is indicated by the normal ok response. Does nothing in
auto-ranging mode. Does nothing upon reaching the most sensitive range.
Turns the Zero Enable function OFF.
Disables the active Applications Setup.
Turns the password function OFF.
