9.1.2. DATA RECORDING DEVICES
A strip chart recorder, data acquisition system or digital data acquisition system should
be used to record data from the T100’s serial or analog outputs. If analog readings are
used, the response of the recording system should be checked against a NIST traceable
voltage source or meter. Data recording device should be capable of bi-polar operation
so that negative readings can be recorded. For electronic data recording, the T100
provides an internal data acquisition system (DAS), which is described in detail in
Section 0.
IMPORTANT
IMPACT ON READINGS OR DATA
Be aware of the difference between Calibration and Calibration Check:
Pressing the ENTR button during the following procedure re-calculates
the stored values for OFFSET and SLOPE and alters the instrument’s
calibration. If you wish to perform a calibration CHECK, do not press
ENTR and refer to Section 9.3.
9.2. MANUAL CALIBRATION
The following section describes the basic method for manually calibrating the T100 SO
2
analyzer.
STEP ONE: Connect the sources of zero air and span gas as shown below.
