VS Series Helium Mass Spectrometer Leak Detectors
The commands listed in Table A-2 are used to set non-volatile operating parameters. The
current value of the operating parameter is changed to the new value. If the leak detector is
in back panel control, the response is cant.

Table A-2 Non-Volatile Operating Parameters
Preceded by 0 or 1, sets the status of Auto-zero < 0. 0 = off, 1 = on.
Preceded by X.XE-X, sets the value of the contra-flow mode crossover
pressure in Torr.
Sets the status of the control panel lockout. Preceded by (0) or (1), 0 =
OFF, 1 = ON.
Sets the system date and time. Preceded by: dow, mm dd yyyy hh mm ss
AmPm 24-12 mode, Where 2 is the day of the week (dow) (0 = Sunday, 1
= Monday, etc), mm/dd/yyyy (date), hh:mm:ss (time) AmPm (0=AM,
1=PM)24-12 mode (0 for 24 hr, 1 for 12 hr). Examples: 2 02 12 2005 04 16

PM)?CURRDATE reports the stored value
Sets the status of the bar graph display to either a log or linear display.
Preceded by (1) Log or (0) Linear.
Sets the emission of the ion source. Preceded by a three-digit number
(micro-amps), in the range 60 to 165.
Sets the range that the leak detector will operate in when Manual Range is
ON. Preceded by 0 to -11.
Sets the value of the external leak. Preceded by a two-digit leak rate
mantissa with a decimal point after the first digit followed by E-, and then
by a two-digit leak range exponent: the helium leak rate number in atm
cc/sec of the calibration standard leak.
Example: 3.2E-08 INIT-EXTLEAK
Sets the operating filament in the ion source. Preceded by a single digit,
either 1 or 2.
Sets the value of the gain used for adjusting the helium signal to match a
calibration standard leak. Preceded by a two-digit number with a decimal
point after the first digit, in the range 1.0 to 6.0.
Note: Changing Gain changes Zero by the same ratio.
