Instruction Manual
READ TRIP POINT Read the 'turns on below'
for RLY B (+) pressure point for relay
B and read the
'turns off above' (-) pressure
point for relay B
READ IG STATUS Finds out the cause of the
ion gauge (IG) shutdown
(1)
Commands marked with a (1) under the "BRIEF DESCRIPTION" column will not take effect until after the RESET
command is sent or power is cycled. This protocol was designed to be compatible with that of the Granville-Phillips® 354
Micro-Ion®.
(2)
After power is cycled, the first #xxRS<CR> query will return a *xx_08_POWER<CR>. A second #xxRS<CR> query will
return *xx_00_ST_OK<CR>. Now, if, for example, power was cycled and an EMIS FAIL error occurred when a subsequent IG
ON condition was attempted, the response to the #xxRS<CR> query will be the sum of the '08' for Power and '02' for EMIS
FAIL in hexadecimal or '0A'. In other words, the response to the #xxRS<CR> command sent after the power cycle and
emission failure events occurred will be *xx_0A_EMISS<CR>.
(3)
The *xx_20_ION_C<CR> response to an Ion Current failure error is not a response available with G-P Micro-Ion.
COMMAND BRIEF DESCRIPTION
SET CGn ZERO Set the zero or vacuum
calibration point for CGn
where n=1=A (as used in the
command syntax) for CG1,
n=2=B for CG2.
Do not confuse the
assignment of RLY A and RLY
B with the distinction of
A=CG1 and B=CG2 used
here, in the command
syntax.
SET CGn SPAN Set the span or atmosphere
calibration point for CGn
READ SW VERSION Read the revision number of
the installed software
SET FACTORY Force unit to return ALL
DEFAULTS settings back to the way the
factory programmed them
before shipment
