Teledyne 9110EH - Nitrogen Oxides Analyzer - Manual (Page 43)

Model 9110EH Instruction Manual Getting Started
Perform the zero/span calibration procedure:
M-P CAL NOX STB=XXX.X PPB NO = X.X
< TST TST > ENTR CONC EXIT
M-P CAL NOX STB=XXX.X PPB NO2= X.X
< TST TST > CAL SETUP
M-P CAL NOX STB=XXX.X PPB NOX= X.X
< TST TST > ZERO CONC EXIT
EXIT returns to the main
SAMPLE display
ACTION:
Allow zero gas to enter the sample port at the
rear of the instrument.
M-P CAL NOX STB=XXX.X PPB NO2= X.X
< TST TST > SPAN CONC EXIT
M-P CAL RANGE = 500.0 PPB NOX = X.X
< TST TST > ENTR SPAN CONC EXIT
M-P CAL RANGE = 500.0 PPB 03 =
< TST TST > ENTR CONC EXIT
Wait until NOX STB
falls below 0.5 ppb.
This may take several
minutes.
The SPAN key now
appears during the
transition from zero to
span.
You may see both keys.
If either the ZERO or
SPAN buttons fail to
appear see Section 11
for troubleshooting tips.
SAMPLE RANGE = 500.0 PPB NOX= X.X
< TST TST > CAL SETUP
SAMPLE NOX STB=XXX.X PPB NO = X.X
< TST TST > CAL SETUP
Set the Display to show the
NOX STB test function.
This function calculates the
stability of the NO/NO
x
measurement
Press ENTR to changes the
OFFSET & SLOPE values for both
the NO and NO
x
measurements.
Press EXIT to leave the calibration
unchanged and return to the
previous menu.
ACTION:
Allow span gas to enter the sample port at the
rear of the instrument.
The value of
NOX STB may jump
significantly.
Wait until it falls back
below 0.5 ppb.
This may take several
minutes.
Press ENTR to change the
OFFSET & SLOPE values for both
the NO and NO
x
measurements.
Press EXIT to leave the calibration
unchanged and return to the
previous menu.
Analyzer
continues to cycle
through NO
x
, NO,
and NO
2
measurements .
The Model 9110EH analyzer is now ready for operation.
