INIT-4REJECT 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
INIT-AREJECT Same as INIT-1REJECT, but for the Audio Reject Set Point.
HIGH-xREJECT 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.
LOW-xREJECT 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.
INIT-ROUGH Sets the Auto Sequencer rough time in seconds. Preceded by XX.
INIT-SYSLEAK 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.
INIT-STDLEAK 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.
INIT-TCTPZERO 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.
INIT-TEMPFACTOR
Sets the temperature correction factor that is printed on the internal cali-
brated leak label. Preceded by –10 to +10.
Example: -7 INIT-TEMPFACTOR
INIT-TEST Sets the Auto Sequencer test time in seconds. Preceded by XX.
LOCK-MS 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.
