Setting-up

Supplying Power to the Model 5725

The Model 5725 VELOCICALC Air Velocity Meter 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 Model 5725 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.

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 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.

Connecting to a Computer

Use the Computer Interface USB Cable provided with the Model 5725 to

connect the instrument to a computer for downloading stored data or for

remote polling. Connect the end labeled “COMPUTER” to the computer

USB port and the other end to the data port of the Model 5725. Then run the

LogDat2 downloading software. Within the LogDat2 software, either select

the tests to be downloaded or double-click on a test to open it.

4Chapter 2

For more 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 Model 5725 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 Model 5725 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 (ST) Keys Press to scroll through choices while setting a

parameter.

(Enter) Key Press to accept a value or condition.

Arrow (gor h) 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,

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 gor hsoft 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 3 types: Round Duct, Rectangle Duct and

Duct Area. Use the gor hsoft 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 Æ

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.
