The following section describes the basic method for manually calibrating the Model
T101 analyzer in H S measurement mode using the IZS option. The same method may

be used to calibrate the T101 analyzers configured for SO
an SO permeation tube be installed in the instrument instead of the standard H
2
(SO permeation tubes differ from H
2
manufacturer).
See Section 6.8 for instructions on calibrating analyzers configured for multigas
measurement mode.
Under the best conditions, the accuracy off the H
permeation tube is about ±5%. This can be subject to significant amounts of drift as the
tube ages and the amount of H
sufficient for calibrating instrument configured for H
calibration checks of instruments measuring SO
calibrations and is not approved for use by the US EPA as a calibration source for
calibrating SO monitoring equipment.

For applications where more stringent calibration requirements are specified for an
instrument with an IZS option installed the following provisions must be followed.
1. Zero air and span gas must be supplied to the analyzer through the
sample gas inlet as depicted in Figure 6-1.
2. The calibration procedure must be initiated using the CAL button (not the
CALZ and CALS buttons) using the procedure defined in Section 6.2.
3. Using the CAL button does not activate the zero/span or sample/cal
valves of the IZS option, thus allowing the introduction of zero air and
sample gas through the sample port from more accurate, external sources
such as a calibrated bottle of H
Calibrator.
