Setting-up

Supplying Power to the Model 7545 IAQ-Calc Indoor Air Quality
Meter

The Model 7545 can be powered in one of two ways: four size AA
batteries or the optional AC adapter.

Installing the Batteries

Insert four AA batteries as indicated by the diagram located on
the inside of the battery compartment. The Model 7545 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 Optional AC Adapter

When using the AC adapter, the batteries (if installed) will be
bypassed. Be sure to provide the correct voltage and frequency,
which is marked on the back of the AC adapter. The AC adapter
is not a battery charger.

Using the 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. Use the probe holder to
support the probe when in continuous data logging mode.

Connecting to a Computer

Use the USB Cable provided with the Model 7545 to connect the
instrument to a computer for downloading stored data.
For more information on how to download stored data see Chapter 3
section titled LogDat2™ Downloading Software.

Caution: This symbol is used to indicate that the data port
of the Model 7545 is not intended for connection to a
public telecommunications network. Connect the USB
data port only to another USB port.
