Model 990 dCLD II Component Leak Detector
A-4
?SETUP Eight lines that report a summary of setup parameters. Each begins with a
<CR><LF>. The format is as follows:
turbo speed Slow
range -05 auto
exponent -08
reject 1.0E-05
stdleak 4.0E-06
output linear
filament Two Lit
use idle no
?STATUS One line which reports, in an ASCII string, the status of the system as reported
by the discrete I/O lines. If the function is inactive, the format is:
REJ/ RDY/
HLD/ FLT/ ZRO/ CAL/
where a three-letter mnemonic is followed by a /. For
example, if a
RDY/
is reported in the string, then the system is not ready. If a
RDY is reported in the string, then the system is ready.
REJ refers to the reject set point
RDY refers to system ready
HLD refers to the system being in the hold mode (used primarily in other leak
detectors)
FLT refers to ion source filament fault
ZRO refers to the zeroing function
CAL refers to the calibration function.
?STDLEAK A seven-character number consisting of a two-digit calibration standard leak
rate mantissa with a decimal point after the first digit followed by E– then a
two-digit calibration standard leak rate range exponent (e.g., 1.3E-07). This
inquiry is used for reporting the internal calibration standard leak rate most
recently input using INIT-STDLEAK.
?SUPPRESSOR Reports the suppressor voltage. The format is: SUPPRESSOR 145.0
?TURBO Three lines that report the turbo status. Each line begins with a <CR><LF>.
The first line consists of the word turbo followed by
Ready or Not Ready .
The second line consists of the word turbo followed by Fault or No Fault .
The third line consists of the word turbo speed followed by Off , Fast , or Slow .
?VARIABLEFOCUS Reports the variable focus voltage. The format is: VARIABLEFOCUS 235.4
VER One line, which reports a date in the form 30 AUG 1995 followed by a six digit
hexadecimal checksum.
