COMMAND BRIEF DESCRIPTION
READ ION GAUGE Read the current displayed
PRESSURE pressure of the ion gauge in
Torr
READ System Read the current IG
Pressure pressure and CG pressure
(IG+CG1 combined)
READ CGn Read the current pressure
Pressure for CGn
SET ADDR OFFSET Set the communications
(RS485) address offset
(upper nibble)
TURN IG ON Power up the filament and
start reading pressure
TURN IG OFF Turns power OFF to the
filament
READ IG ON/OFF Find out if filament is
STATUS powered up and gauge is
reading
TURN DEGAS ON Start a degas cycle
TURN DEGAS OFF Stop a degas cycle
READ DEGAS Find out if the module is
STATUS currently degassing

RESPONSE
*xx_y.yyEzpp<CR>
where y.yy = mantissa, z = sign
of the exponent, i.e., +/- and pp
= the exponent.
(e.g., *01_1.53E-06<CR>)
When IG is off: *01_9.90E+09
*xx_y.yyEzyy<CR>
(e.g., *01_1.53E-06<CR>)
When IG is off: CG only
*xx_ y.yyEzyy <CR>
(e.g., *01_7.60E+02<CR>)
When CG is over-ranged or not
plugged in: *01_1.01E+03<CR>
*xx_PROGM_OK<CR>
*xx_PROGM_OK<CR>
When CG controlled:
?01_INVALID_<CR>

?01_INVALID_<CR>
*xx_PROGM_OK<CR>
(clears any errors)
*xx_0_IG_OFF<CR>
*xx_1_IG_ON_<CR>
*xx_PROGM_OK<CR>
