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.

Velocity From a Pitot Tube:

Range2: 250 to 15500 ft/min (1.27 to 78.7 m/s)
Accuracy3: ±1.5% at 2000 ft/min (10.16 m/s)
Resolution: 1 ft/min (0.1 m/s)

Instrument Temperature Range:

Operating (Electronics): 40 to 113°F (5 to 45°C)
Storage: -4 to 140°F (-20 to 60°C)

Instrument Operating Conditions:

1

Overpressure range = 7 psi (190 in. H2O, 360 mmHg, 48 kPa).

2

Pressure 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.

3

Accuracy is a function of converting pressure to velocity. Conversion accuracy

improves when actual pressure values increase.
