Chapter 2 Setting-up

Supplying Power to the Alnor® Model AXD620/ Airflow™ Instruments PVM620
The Alnor® AXD620/Airflow™ Instruments PVM620 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® AXD620 / Airflow™ Instruments 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.

Connecting to a Computer

• Use the Computer Interface USB Cable to connect the instrument to a computer.
• For information on how to download stored data see Chapter 3 LogDat2™ Downloading Software.

	C A U T I O N
	This symbol is used to indicate that the data port of the Alnor® AXD620/Airflow™ Instruments PVM620 IS NOT intended for connection to a public telecommunications network. Connect the USB data port only to another USB port.

Chapter 3 Operation

Keypad Functions 

ON/OFF Key	Press to turn the Alnor® Model AXD620 / Airflow Instruments PVM620 on and off. During the power up sequence the display will show the following: Model Number, Serial Number and Software Revision.
Arrow () Keys	Press to scroll through choices while setting a parameter.
(Enter) Key	Press to accept a value or condition.
Arrow ( or ) and Menu Soft Keys	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.

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.

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
Turn the instrument on for a minimum of five minutes to let it warm up before zeroing the pressure sensor. 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. Use the     or soft keys to scroll through the settings for each option and use the key to accept settings.

FLOW SET UP
In Flow Setup mode, there are four types: Round Duct, Rectangle Duct, Duct Area, and K-Factor. Use the or soft keys to scroll through the types and then press the  key to accept the desired type. To change the setting, highlight the Enter Settings option and press the key.

Press/Kfact allows for calculating flow rate from diffusers or flow stations with pressure taps using the instruments pressure ports and K-factors. The K-factors are obtained from the diffuser or flow station manufacturer. For more information, refer to Application Note TSI-114.

• Up to 5 K-factors can be pre-programmed for quick use.
• When Flow is set as the Primary measurement in the Display Setup menu, the K-factor will also be displayed.

When measuring Flow as the Primary measurement, the parameters can be quickly changed by pressing the or key while on the main measurement screen. Make adjustments with the or arrow keys and press to accept, or enter the Select Kfactor menu to choose a different pre-programmed flow value.

ACTUAL/STANDARD SETUP
Choose Actual/Standard measurements and parameters in the Act/Std Setup menu. Within this menu, you 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. The Entered Temp range is from -40 to 1832°F (-40 to 1000°C).

DATA LOGGING

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

• When set to ON, measurement will be logged to memory.
• When set to DISPLAY, measurement will be logged to memory if it is visible on the main running screen.
• When set to OFF, measurement will not be logged to memory.

Log Mode/Log Settings
You can set Log Mode to Manual, Auto-save, or Cont-key.

• Manual mode does not automatically save data, but instead prompts you to save a sample.
• In Auto-save mode, you manually take samples that are automatically logged.
• In Cont-key mode, you start taking readings and logging by pressing the key. The instrument will continue taking measurements until the key is pressed again.
• Auto-save and Cont-Key modes have the following additional Log Settings:
