batteries.

Installing the Batteries

Insert four AA batteries as indicated by the diagram located on the
inside of the battery compartment. The Alnor AXD620/A
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.

IRFLOW PVM620 is powered with four size AA

IRFLOW

Connecting to a Computer

Use the Computer Interface USB Cable to connect the instrument to a
computer. Connect the end labeled “COMPUTER” to the computer USB
port and the other end to the data port of the Alnor AXD620/A
PVM620.

For information on how to download stored data see Chapter 3

Downloading Software.

Caution: This symbol is used to indicate that the data port

Common Terms

In this manual there are several terms that are used in different places. The
following is a brief explanation of the meanings of those terms.

Sample

Test ID

Press to turn the Alnor Model AXD620/A
PVM620 on and off. During the power up
sequence the display will show the following:
Model Number, Serial Number, Software Revision
and Last Date Calibrated.

Press to scroll through choices while setting a
parameter.

Press to accept a value or condition.

Press arrow keys to change choices while setting a
parameter. Press the Menu soft key to select the
Menu selections, which are Display Setup,
Pressure Zero, Settings, Flow Setup, Actual/Std
Set up, Data Logging, and Calibration.

Consists of all of the measurement parameters
stored at the same time.

A group of samples. The statistics (average,
minimum, maximum, and count) are calculated for
each test ID. The maximum number of test IDs is

100.

Time Constant

The time constant is an averaging period. It is used
to dampen the display. If you are experiencing
fluctuating flows, a longer time constant will slow
down those fluctuations. The display will update
every second, but the displayed reading will be the
average over the last time constant period. For
example, if the time constant is 10 seconds, the
display will update every second, but the displayed
reading will be the average from the last 10
seconds. This is also referred to as a “moving
average”.

Log Interval

Menus

DISPLAY SETUP

Display setup menu is where you will setup the desired parameters to be
displayed on the running screen. With a parameter highlighted you can then
use the ON soft key to have it show up on the running screen or select the
OFF soft key to turn off the parameter. Use PRIMARY soft key to have a
parameter show up on the running screen in a larger display. Only one
parameter can be selected as a primary, and up to 2 secondary parameters
can be selected at one time.

PRESSURE ZERO

To zero the pressure reading, select the Pressure Zero menu. The instrument
will indicate if the pressure zero was successful.

SETTINGS

Settings menu is where you can set the general settings. These include
Language, Beeper, Select Units, Time Constant, Contrast, Set Time, Set
Date, Time Format, Date Format, Number Format, Backlight and Auto Off.

The logging interval is a frequency period that the
instrument will log readings. For example, if the
logging interval is set to 30 minutes, each sample
will be the average of the last 30 minutes.

FLOW SET UP

In Flow Setup mode, there are four types: Round Duct, Rectangle Duct, Duct
Area, and K-Factor. Use the g
then press the  key to accept the desired type. To change the setting,
highlight the Enter Settings option and press the  key.

or h soft keys to scroll through the types and

NOTE: K-Factors are intended for use with diffusers with pressure taps
and a manufacturer-supplied K factor.

ACTUAL/STANDARD SETUP

Choose Actual/Standard measurements and parameters in the Act/Std Setup
menu. Within this menu, the user can also select Standard Temperature,
Standard Pressure and a source for the actual temperature. The actual
barometric pressure must be entered to convert air velocity and volume
measurements to actual conditions.

DATA LOGGING

Measurements

Measurements to be logged are independent of measurements on the
display, and must therefore be selected under DATA LOGGING Æ
Measurements.

Log Mode/Log Settings

You can set Log Mode to Manual and Auto-save.

• Manual mode does not automatically save data, but instead prompts

the user to save a sample.

• In Auto-save mode, the user manually takes samples that are

automatically logged.

• The Log Interval setting is active during Auto-save mode

Delete Data

Use this to delete all data, delete test or delete sample.

% Memory

This option displays the memory available. Delete All, under Delete
Data, will clear memory and reset the memory available.
