5.3. MANUAL CALIBRATION CHECKS

Scroll the display to the
STABIL test function.
Wait until
STABIL is
below 1.0 ppm.
This may take
several minutes.
The value of
STABIL may jump
significantly.
Wait until it falls
below 1.0 ppm. This
may take several
minutes.

5.4. MANUAL CALIBRATION WITH ZERO/SPAN VALVES

07272B DCN6552
Informal calibration checks, which only evaluate but do not alter the analyzer's
response curve, are recommended as a regular maintenance item and in order to
monitor the analyzer's performance. To carry out a calibration check rather than
a full calibration, follow these steps.
STEP ONE: Connect the sources of zero air and span gas as shown in Figures
7.1 or 7.2.
STEP TWO: Perform the zero/span calibration check procedure:
Supply the instrument with zero gas.
SAMPLE RANGE = 500.0 PPM
< TST TST > CAL
SAMPLE STABIL=XXX.X PPM
< TST TST > CAL
SAMPLE STABIL=XXX.X PPM
< TST TST > CAL
Supply span gas to the instrument
SAMPLE STABIL=XXX.X PPM
< TST TST > CAL
The SPAN key appears during the transition from zero to
span. You may see both SPAN and ZERO buttons.
There are four different zero/span valve option configurations (see Figure 5-3
through Figure 5-6). They all operate identically, differing only in the method
used to supply calibration gas to the Analyzer.
STEP ONE: Connect the sources of Zero Air and Span Gas as shown below.
Figure 5-3 through Figure 5-6 show the proper pneumatic connections for T360s
with various optional internal valve sets installed.
