A-7
?SETUP Reports seven lines, each begins with a <cr><lf>. The first line reports the
turbo pump speed with the RPM value or OFF. The second line reports the
selected manual leak rate range, and the ranging method as auto or
manual. The third line reports the least sensitive leak rate range. The fourth
line reports the reject set point leak rate. The fifth line reports the internal
calibrated leak rate value. The sixth line reports the DAC output method as
Linear, Log(2V), or Log(3V). The seventh line reports the active filament
status as One or Two, followed by Lit or Out.
?SPLITFLOW Returns the status of the split flow function, ON or OFF.
?STDLEAK Reports a six-character number consisting of a two-digit calibration
standard leak rate mantissa with a decimal point after the first digit
followed by E-, and then by a two-digit exponent (e.g., 1.3E-07). This
inquiry is used for reporting the calibration standard leak rate entered
using INIT-STDLEAK.
?SYSLEAK Reports the leak rate value that has been stored that relates to the split flow
functionality.
?SYSPWD Reports the value of the system password.
?TEST Reports the currently stored Test Sequencer test time used as part of setting
up the Auto Sequencer.
?TEMPFACTOR Reports the internal calibrated leak temperature factor that is used as part
of the temperature correction logic (degrees C).
?TURBO Reports four lines, each begins with a <cr><lf>. The first line consists of
the word turbo followed by either READY or NOT READY. The second line
consists of the word turbo followed by either Fault or No Fault. The third
line consists of the words turbo speed RPM followed by the RPM value:
xxxxx. The fourth line consists of the words "Turbo Temp (Celsius):"
followed by the bearing temperature value: XX.
?VALVESTATE Reports the current mode of the valves: Vent, Hold, etc.
VER Reports the CPU software version in the form LC02.05 followed by a six
digit hexadecimal checksum.
?VOLUMEONOFF Reports audio as either ON or OFF.
WHYNOCAL Reports the calibration failure diagnostics.
?0ENABLE Responds with the status of the Zero Enable function, ON or OFF.
