Technical Information
The commands listed in the following table 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.

Parameter
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
33 1 0 INIT-DATE(Tuesday, February 12, 2005, 4:16:33 on a 24 hr clock)2
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 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.
