Teledyne 200E - Perform Zero;Span Calibration

Calibration Procedures Model 200E Instruction Manual
NOTE
The expected concentrations for both NO
X
and NO are usually set to the same
value unless the conversion efficiency is not equal to 1.000 or not entered
properly in the conversion efficiency setting. When setting expected concentration
values, consider impurities in your span gas source (NO often contains 1-3% NO
2
and vice versa).
7.2.3. Perform Zero/Span Calibration:
M-P CAL NOX STB=0.5 PPB NO = X.X
< TST TST > ENTR CONC EXIT
M-P CAL
NOX STB=0.5 PPB
NO2= X.X
< TST TST > CAL SETUP
M-P CAL NOX STB=0.5 PPB NOX= X.X
< TST TST > ZERO CONC EXIT
EXIT returns to the main
SAMPLE display
A
CTION:
Supply the instrument with zero air.
M-P CAL NOX STB=XXX.X PPB NO2= X.X
< TST TST > SPAN CONC EXIT
M-P CAL NOX STB=XXX.X PPB NOX = X.X
< TST TST > ENTR SPAN CONC EXIT
M-P CAL NOX STB=XXX.X PPB NO2 =X.X
< 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.
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
Scroll the display to the NOX
STB function, which calculates
the standard deviation of the
NO/NO
x
measurement
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 (for cal checks).
A
CTION:
Supply the instrument with span gas.
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 (for cal checks).
Analyzer
continues to cycle
through NO
X
, NO,
and NO
2
measurements .
