Setting-up
Supplying Power to the Alnor RVA501/Airflow Instruments
LCA501
The Alnor RVA501/Airflow
LCA501
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 RVA501/Airflow
LCA501 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.
Attaching the Handle
To attach the handle, screw the handle into the bottom of the
rotating vane head until secure. Remove the handle after use to
prevent damage to either the head or the handle.
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.
Using the Optional Articulating Extension
The articulating extension allows you to secure the vane head at
nearly any angle. Once you have attached the articulating
extension, you can unscrew the swivel adjustment bolt, and
adjust the angle of the elbow. You can then adjust the pivot
position of the head by partially unscrewing the head from the
handle and tightening it with the knurled knob, located
underneath the vane head.
