Step Three: Perform the calibration or calibration check according to the following flow
chart:
Wait until H2S
STB falls below
0.5 ppb. This may
take several
minutes. ZERO CAL M H2S STB=XXX.X PPB H2S =XXX.X
< TST TST > ZERO CONC EXIT
EXIT returns to the
main SAMPLE
display
ZERO CAL M H2S STB=XXX.X PPB H2S =XXX.X
< TST TST > ENTR CONC EXIT
Pressing ENTR changes the calibration of the instrument.
If either the ZERO or
SPAN button fails to
appear, see Chapter 11
for troubleshooting tips.
Analyzer enters ZERO
CAL mode .
EXIT returns the unit to
SAMPLE mode without
changing the calibration
values.
ZERO CAL M H2S STB=XXX.X PPB H2S =X.XXX
< TST TST > ZERO CONC EXIT
ZERO CAL M H2S STB=XXX.X PPB H2S =XXX.X
< TST TST > CAL CALZ CALS SETUP
SPAN CAL M H2S STB=XXX.X PPB H2S =XXX.X
< TST TST > SPAN CONC EXIT
SPAN CAL M H2S STB=XXX.X PPB H2S =XXX.X
< TST TST > ENTR CONC EXIT
EXIT returns to the
SAMPLE mode without
changing the calibration
values.
SPAN CAL M H2S STB=XXX.X PPB H2S =XXX.X
< TST TST > SPAN CONC EXIT
ACTION:
Allow zero gas to enter the sample port at the
rear of the instrument.
SAMPLE RANGE = 500.0 PPB H2S =XXX.X
< TST TST > CAL CALZ CALS SETUP
SAMPLE H2S STB=XXX.X PPB H2S =XXX.X
< TST TST > CAL CALZ CALS SETUP
Scroll the display to the H2S
STB test function. This function
calculates the stability of the
H
2
S measurements.
The value of H2S
STB may jump
significantly. Wait
until it falls below 0.5
ppb. This may take
several minutes.
Pressing ENTR changes the calibration of the instrument.
Analyzer enters SPAN
CAL Mode.
