Chapter 2 Setting-up
Supplying Power to the Model 7515 IAQ-CalcTM 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.
Chapter 3 Operation
Keypad Functions
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
▲▼ ENTER keys to adjust the concentration displayed on the instrument to
match the concentration on the gas cylinder.
Chapter 4 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 Service Request number. To fill out an online

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.
