CHAPTER 6

Calibration

Gas Sensors

TSI® recommends testing the accuracy of gas sensor measurements
each time the instrument is used. This is a common practice within
the gas measurement community which includes IAQ consultants
and industrial hygienists. Due to the nature of the sensors along with
other environmental factors such as altitude, temperature, and
relative humidity, the zero value and sensor sensitivity can shift over
time requiring you to perform a field calibration.

Gas Sensor Verification

Verifying the accuracy and
performance of a sensor can easily
be accomplished in the field by
comparing it to certified ZERO and
SPAN calibration gases (also
referred to as a “Bump Test”). To
do this, attach a calibration cap to
a bottle of the recommended
ZERO gas and place the cap onto
the gas sensor being checked. If
the probe reads a number outside
of the sensor accuracy after the
measurement has stabilized, the
sensor has drifted and needs to be
recalibrated. Perform the same
procedure with the recommended
SPAN gas to check the sensor
measurement against the certified
SPAN bottle concentration and
determine if a user calibration is
necessary. See Table 1 for recommended ZERO and SPAN gases.

32 Q-Trak™ XP IAQ Monitor Model 7585

NOTE

For best results, power on the instrument for 10 minutes before
verifying gas sensor performance. This allows the instrument and
sensors to thermally stabilize and reduces the amount of
measurement drift during verification or calibration.

NOTE

Specific instructions for the calibration of each sensor are
available during calibration. To access the help for a sensor,
select and a pop-up appears with information to guide you
through specific sensor calibrations.

The following table shows the recommended calibration gases
and their respective concentrations (in ppm) for each gas sensor.

Calibration gases are available globally through local
distributors.

APPENDIX B

Definitions

Out-of-Range
(Calibration)

An Out-of-Range error during the calibration of a

sensor means the sensor’s offset or calibration

slope adjustment has drifted outside of the TSI®
recommended specification for continued use.
Sensor should be replaced or sent to TSI® for
recalibration.

Test Duration

The time over which the data will be logged while
in Continuous Save mode. The test duration
can be set from 1 second to 99 hours:
59 minutes: 59 seconds.

Sample Interval

The sample interval is the time period where data
is collected and averaged to produce a single
value. For example, if the sample interval is set
to 1 minute, each 1 second sample will be
averaged over the minute and result in a single
value. The sample interval can be set from
1 second to 99 hours: 59 minutes: 59 seconds.
However, the sample interval cannot be greater
than the test duration.

Time Constant

The time constant is an averaging period for the
readings shown on the display. It is used to
dampen fluctuations in the measurement to
make it easier to read. If there are significant
fluctuations in the readings, a longer time
constant setting will reduce the fluctuations. The
display will update ever second; however, the
displayed reading will be the average over the
time constant period. For example, if the time
constant is 5 seconds, the display will update
every second, but the displayed reading will be
the average of the last 5 seconds.
