Setting-up
Supplying Power to the Alnor®AXD610/Airflow™Instruments
PVM610
The Alnor®AXD610/Airflow™Instruments PVM610 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®AXD610 /
Airflow™Instruments PVM610 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.

power up sequence the display will show the
following: Model Number, Serial Number,
Software Revision and Last Date Calibrated.
ft/min / m/s Key
Pressing this key changes the display to read
air velocity, converted from velocity pressure
when connected to a pitot probe.
in H2O / Pa / hPa /
kPa / mm HG Key
Pressing this key changes the display to read
differential pressure.
0 Key
Pressing the 0 key zeroes the pressure
measurement. Turn the instrument on for a
minimum of five minutes to let it warm up
before zeroing the pressure sensor.
Changing Units
To change units, first put the desired
measurement (air velocity or pressure) on
the display. Then press and hold the left,
unlabeled key for five seconds. Finally, use
the  and ENTER key to select the units.
