Setting-up
Supplying Power to the Alnor AXD610/AIRFLOW PVM610
The Alnor AXD610/AIRFLOW 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
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.

Operation
Keypad Functions
ON/OFF Key Press to turn the Alnor AXD610/AIRFLOW
PVM610 on and off. During the 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.
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.
Changing Units To change units, first put the desired measurement
(air velocity or temperature) on the display. Then
press and hold the left, unlabelled key for five
seconds. Finally, use the ST and ENTER key to
select the units.

1Overpressure range = 7 psi (190 in. H2O, 360 mmHg, 48 kPa).
2Pressure velocity measurements are not recommended below 1,000 ft/min (5 m/s) and are
best suited to velocities over 2000 ft/min. Range can vary depending on barometric
pressure.
3Accuracy is a function of converting pressure to velocity. Conversion accuracy improves
when actual pressure values increase.
