6.3. MANUAL CALIBRATION CHECKS

Scroll the display to the
H2S STB test function.
Wait until H2S
STB is below
0.5 ppb. This
may take
several minutes.
The value of H2S
STB may jump
significantly.
Wait until it falls
below 0.5 ppb. This
may take several
minutes.
Informal calibration checks, which 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.
The following section describes the basic method for manually checking the calibration of
the Model T101 analyzer in H
manually check the calibration of the T101 analyzers configured for SO
substituting SO span gas for the H

performing calibration checks on analyzers configured for multigas measurement mode.
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 Figure 6.1.
STEP TWO: Perform the zero/span calibration check procedure:
Supply the instrument with zero gas.
