Response
Reports a six-character number consisting of a two-digit leak rate mantissa with decimal
point after the first digit followed by E - then a two digit number, which is the leak rate range
exponent (e.g., 1.3E-08).
Reports the internal calibrated leak expiration date mm/dd/yyyy.
Reports the internal calibrated leak temperature that the factory calibration was performed
at (degrees C).
Reports the current leak rate along with the test port and system pressures.
Reports the current Leak Rate, Pressures and Valve state.
Reports the current Test to Fine Test crossover pressure setpoint in Torr. The response is in
exponential format (in Torr): X.XE-XX
CommandtoqueryifthepreheatIonsourcePCBisinstalled A response of 0 = No, 1 = Yes
A numerical response in minutes.
Reports two lines. Each begins with a <cr><lf>. The first line consists of the words test port
TC followed by a number in mTorr. The second line consists of the words system TC
followed by a number in uTorr.
Response will be a number (1, 2 or 3).
Reports status of system password (ON or OFF).
Reports whether Fast or Full Calibration is chosen if a calibration were to be started.
Reports the value of the Range Stop variable.
Reports the reject leak rate setpoint (e.g., 7.0E-05) (where x is a number from 1 to 4 or the
letter A).
Reports the status of a reject set point (where x is a number from 1 to 4 or the letter A).
Reports the reject leak rate setpoint (e.g., 7.0E-05) (where x is a number from 1 to 4 or the
letter A).
Reports the currently stored Test Sequencer rough time used as part of setting up the Auto
Sequencer.
Reports the status of the Rangestop function as Enabled or Disabled.
Reports the status of the Auto Sequencer as Enabled or Disabled.
