Setting-up
Supplying Power to the Alnor Model AXD620/Airflow
Instruments PVM620
The Alnor AXD620/Airflow Instruments PVM620
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 Alnor AXD620/Airflow
Instruments PVM620 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
will not recharge the batteries.
Connecting to a Computer
Use the Computer Interface USB Cable to connect the instrument to
a computer.
