9.1.3. DATA RECORDING DEVICES
A strip chart recorder, data acquisition system or digital data acquisition system should
be used to record data from the serial or analog outputs of the T200.

If analog readings are used, the response of the recording system should be
checked against a NIST traceable voltage source or meter.

Data recording devices should be capable of bi-polar operation so that negative
readings can be recorded.
For electronic data recording, the T200 provides an internal data acquisition system
(DAS), which is described in detail in Section 7.
APICOM, a remote control program, is also provided as a convenient and powerful tool
for data handling, download, storage, quick check and plotting (see Sections 7.2.1, and
the APICOM software manual downloadable from:

9.1.4. NO
2
CONVERSION EFFICIENCY (CE)
In order for the NO
2
converter to function properly, oxygen must be present in the
sample stream. In addition, to ensure accurate operation of the T200, it is important to
check the NO
2
conversion efficiency (CE) periodically and to update this value as
necessary.

See Section 12.7.10 for instructions on checking or calculating the current NO


NO converter efficiency using T200’s onboard firmware.

See Section 12.7.11 for instructions on checking or calculating the current NO


NO converter efficiency using a simplified Gas Phase Titration Method.

ZERO/SPAN CALIBRATION CHECKS VS. ZERO/SPAN CALIBRATION
Pressing the ENTR button during the following procedure resets the stored
values for OFFSET and SLOPE and alters the instrument’s Calibration.
This should ONLY BE DONE during an actual calibration of the T200.
NEVER press the ENTR button if you are only checking calibration.
