Parameter
Sets the test port pressure value for Reject Set Point #4. 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
exponent: the test port TC pressure in millitorr.
Example 1.5E-02 INIT-4REJECT.
Same as INIT-1REJECT, but for the Audio Reject Set Point.
Sets the reject set point to activate when the actual test value is higher than the set point.
Where x is a number from 1 to 4 or the letter A. For example, the reject set point is set for
7.0E-05 and the actual test value is 9.2E-05.
Sets the reject set point to activate when the actual test value is lower than the set point.
Where x is a number from 1 to 4 or the letter A. For example, the reject set point is set for
7.0E-05 and the actual test value is 4.3E-07.
Sets the Auto Sequencer rough time in seconds. Preceded by XX.
Sets the split flow leak value, system must be in TEST and the split flow feature must be
OFF when this parameter is set. 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.
Example 3.4E-08 INIT-SYSLEAK.
Sets the value of the internal 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.
Example: 3.2E-08 INIT-STDLEAK.
Used to calibrate the low-pressure end of the test port thermocouple to a known pressure
higher than zero. Preceded by a number (XX) of mTorr representing the test port pressure at
the time of the command.
Sets the temperature correction factor that is printed on the internal calibrated leak label.
Preceded by –10 to +10.
Example: -7 INIT-TEMPFACTOR
Sets the Auto Sequencer test time in seconds. Preceded by XX.
Enables the MS lock feature. If the system exceeds 150 mTorr, the system goes from Fine
test directly into Roughing mode (no Contra mode). If the leak rate exceeds the 7 range, the
over range symbol appears.
Disables the MS lock feature.
Queries the status of the MS lock feature; either on or off appears.
