Model 990 dCLD II Component Leak Detector
A-2
Table A-1 through Table A-4 outline the available control and query commands.
❑
Table A-1 lists inquiries that are used to determine internal operating parameters. All
inquiries, except VER, begin with
?
and end with <CR>.
❑
Table A-2 lists commands used to set NON-VOLATILE operating parameters.
❑
Table A-3 lists commands that are used to cause an immediate change in the
spectrometer operating parameters. These commands do not change the non-volatile
operating parameters.
❑
Table A-4 lists commands that are used to cause certain leak detection actions.
The inquiries listed in Table A-1 are used to determine internal operating parameters. All
inquiries, except ver, begin with
?
and end with <CR>.
Table A-1 Internal Operating Parameters
Inquiry Response
?ALL Nine lines that report a summary of all ion source parameters. Each begins with
a <CR><LF>. The format is as follows:
FILAMENTBIAS 122.1
IONCHAMBER 269.1
VARIABLEFOCUS 235.4
REPELLER 402.2
FIXEDFOCUS 212.7
SUPPRESSOR 145.0
EMISSIONCURRENT 1.040
OFFSET 59
GAIN 1.5
?AZ<0 The response is yes or no indicating that AUTO-ZERO<0 is enabled or
disabled.
?CALOK Reports status of the last calibration. The response is yes or no .
?EMISSIONCURRENT Reports the emission current. The format is: EMISSIONCURRENT 1.040
?EXPONENT A three-character (minus followed by two digits) number indicating the current
manual-mode exponent. The exponent is within the least sensitive range (as
reported by ?RANGE<CR>) and the three lower (more negative exponent)
ranges. Also see INIT-EXPONENT.
