Setting-up
Supplying Power to the Model 5725
The Model 5725 V
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.
ELOCICALC Air Velocity Meter is powered with four size
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.

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 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.
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,
Settings, Flow Setup, 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”.

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 g
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 g or h 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.
or h soft keys to scroll through the settings for each option and
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.
6 Chapter 3
• Auto-save and Cont-Key modes use Log Interval under the
Log Settings:

Auto-save Log Interval
Cont-key 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 Model 5725 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 Model 5725, connect the supplied computer
interface USB cable to the Model 5725 and to a computer USB port. Then

The Model 5725 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, multiple-point 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 Model
5725. If the enclosure of the Model 5725 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.
