Setting-up
Supplying Power to the Model 7515 IAQ-CALC Indoor Air Quality Meter
The Model 7515 is powered with four size AA batteries.
Installing the Batteries
Insert four AA batteries as indicated by the diagram located on
the inside of the battery compartment. The Model 7515 is
designed to operate with either alkaline or NiMH rechargeable
batteries, although it will not recharge NiMH batteries. Battery life
will be shorter if NiMH batteries are used. Carbon-zinc batteries
are not recommended because of the danger of battery acid
leakage.
Using the Integral Probe
The sensing probe relies on the diffusion of air. For best results,
try to keep the sensing probe surrounded by moving air. Do not
breathe on the probe. Humans exhale CO2 levels exceeding
10,000 ppm and it may take time for the probe to re-stabilize.

ON/OFF Key
Press to turn the Model 7515 on and off.
During the power up sequence the display will
show the following: Model Number, Serial
Number, Software Revision, and Last Date
Calibrated.
Sample Key
Press and release to start the sample, then
press the END key to stop the sample.
Stats Key
Press to view the minimum, maximum and
average of the last sample taken.
CAL Key
Press to begin the field-calibration process.
To re-calibrate in the field, first connect zero
gas to the instrument and open the regulator.
The instrument will automatically make zero
itself after one minute.
After zeroing the sensor, connect span gas to
the instrument and open the regulator. The
instrument will take one minute to make a
reading. Then use the and ENTER keys
to adjust the concentration displayed on the
instrument to match the concentration on the
gas cylinder.

Maintenance
The Model 7515 requires very little maintenance to keep it performing
well.
Recalibration
To maintain a high degree of accuracy in your measurements, we
recommend that you return your Model 7515 to TSI for annual
recalibration. Please contact one of TSI’s offices or your local
distributor to make service arrangements and to receive a Return
Material Authorization (RMA) number. To fill out an online RMA form,
visit TS
The Model 7515 can also be recalibrated in the field using the
CALIBRATION menu. These field adjustments are intended to make
minor changes in calibration to match a user's calibration standards.
The field adjustment is NOT intended as a complete calibration
capability. For complete, multiple-point calibration and certification,
the instrument must be returned to the factory.
Cases
If the instrument case or storage case needs cleaning, wipe it off with
a soft cloth and isopropyl alcohol or a mild detergent. Never immerse
the Model 7515. If the enclosure of the Model 7515, it must be
replaced immediately to prevent access to hazardous voltage.
Storage
Remove the batteries when storing the unit for more than one month
to prevent damage due to battery leakage.
