Setting-up
Supplying Power to the Alnor RVA501/Airflow Instruments LCA501
The Alnor RVA501/Airflow LCA501 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 RVA501/Airflow LCA501 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.
Attaching the Handle
To attach the handle, screw the handle into the bottom of the rotating vane head until secure. Remove the handle after use to prevent damage to either the head or the handle.
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.
Using the Optional Articulating Extension
The articulating extension allows you to secure the vane head at nearly any angle. Once you have attached the articulating extension, you can unscrew the swivel adjustment bolt, and adjust the angle of the elbow. You can then adjust the pivot position of the head by partially unscrewing the head from the handle and tightening it with the knurled knob, located underneath the vane head.

Using the Optional Air Cone Kit
Air Cone Flow Hoods are a fast and accurate method of maximizing the usefulness of your 100 mm (4 in.) rotating vane anemometer by turning it into an air volume balancing tool. Kit comes with both rectangular 285 mm x 235 mm (11.2 in. x 9.2 in.) and circular 180 mm (7.1 in.) diameter cones. Simply slide the vane head into the Air Cone to perform supply or extract/return measurements. Kit includes instructions for usage.
Connecting to a Computer
Use the Computer Interface USB Cable provided with the Alnor RVA501/Airflow Instruments LCA501 to connect the instrument to a computer for downloading stored data.
For information on how to download stored data see Chapter 3 section titled LogDat2 Downloading Software.
Caution: This symbol is used to indicate that the data port of the Alnor RVA501/Airflow Instruments LCA501 is not intended for connection to a public telecommunications network. Connect the USB data port only to another USB port.

Operation
Keypad Functions
ON/OFF Key
Press to turn the Alnor RVA501/Airflow Instruments LCA501 on and off. During the power up sequence the display will show the following: Model Number, Serial Number, Software Revision and Last Date Calibrated.
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, Settings, Flow Setup, 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.
Sample
Consists of all of the measurement parameters stored at the same time.
Test ID
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”.

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.
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 Air Cone. Use the or soft keys to scroll through the types and then press the key to accept the desired type. To change the value, highlight the Enter Settings option and press the key.
DATA LOGGING
Measurements
Measurements to be logged are independent of measurements on the display, and must therefore be selected under DATA LOGGING Measurements.
Log Mode/Log Settings
You can set Log Mode to Manual or 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.
In Cont-key mode, the user starts taking readings and logging
by pressing the key. The instrument will continue taking measurements until the key is pressed again.

Log Interval
Use Cont-key mode with Log Interval set to 1 second to take
a Sweep measurement across an area.
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.
LogDat2 Downloading Software
The Alnor RVA501/Airflow Instruments LCA501 comes with special software called LogDat2 Downloading Software, which is designed to provide you with maximum flexibility and power. To install this software on your computer, follow the instructions on the label of the LogDat2 CD-ROM.
To download data from the Alnor RVA501/Airflow Instruments LCA501, connect the supplied computer interface USB cable to the Alnor RVA501/Airflow Instruments LCA501 and to a computer USB port. Then run the LogDat2 downloading software. Within the LogDat2 software, either select the tests to be downloaded or double­click on a test to open it.

The Alnor RVA501/Airflow Instruments LCA501 can also be recalibrated in the field using the CALIBRATION menu. These field adjustments are intended to make minor changes in calibration to match a user's calibration standards. The field adjustment is NOT intended as a complete calibration capability. For complete, multiple­point calibration and certification, the instrument must be returned to the factory.
Cases
If the instrument case or storage case needs cleaning, wipe it off with a soft cloth and isopropyl alcohol or a mild detergent. Never immerse the Alnor RVA501/Airflow Instruments LCA501. If the enclosure of the Alnor RVA501/Airflow Instruments LCA501 or the AC adapter becomes broken, it must be replaced immediately to prevent access to hazardous voltage.
Storage
Remove the batteries when storing the unit for more than one month to prevent damage due to battery leakage.
