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 CO
take time for the probe to re-stabilize.

Press and release to start the sample, then press the
END key to stop the sample.

Press to view the minimum, maximum and
average of the last sample taken.

Press to begin the field-calibration process. To re­calibrate in the field, first connect zero gas to the
instrument and open the regulator. Then use the

ST and ENTER keys to select ZERO. The

instrument will automatically make zero itself after
one minute.

After zeroing the sensor, connect span gas to the
instrument and open the regulator. Then use the

ST and ENTER keys to select SPAN. The

instrument will take one minute to make a reading.
Then use the
concentration displayed on the instrument to
match the concentration on the gas cylinder.

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.
