low coef 1
low coef 2
The “coef 0”, coef 1”, and coef 2” commands report the coefficients of the
curve developed from the Hi Multi-Point Calibration in single range mode.
The “high coef 0”, high coef 1”, and high coef 2” commands report the
coefficients of the curve developed from the Hi Multi-Point Calibration in
dual or auto range mode. The “low coef 0”, low coef 1”, and low coef 2”
commands report the coefficients of the curve developed from the Lo
Multi-Point Calibration in dual and auto range mode. The following
example reports the coefficient 0 having a value of 1.005.
Send:
coef 0
Receive:
coef 0 1.005 ok
hcl bkg
This command reports the current HCl backgrounds. The following
example reports that the HCl background is 1.4 ppm.
Send:
hcl
bkg
Receive:
hcl bkg 1.400 ppb
set hcl bkg
value
This command is used to set HCl backgrounds to user-defined values to
value
, where
value
is a floating-point representation of the background in
current selected units. The following example sets the HCl background to
1.4 ppm.
Send:
set hcl bkg 1.400
Receive:
set hcl bkg 1.400 ok
init ratio
This command reports the initial sample/reference ratio. The following
example reports that the initial ratio is 1.100000.
Send:
init
ratio
Receive:
init ratio 1.100000
sp conc
high sp conc
low sp conc
These commands report span concentration in single range mode, or the
high and low span concentrations in dual or auto range mode. If the mode
is incorrect, the instrument responds with “can’t, wrong settings”. The
following example reports the span gas concentration in single range mode.
Send:
sp
conc
Receive:
sp conc 5.000E+03 ppb
