INTRODUCTION

Thank you for purchasing the OM-143 USB RH/Temperature

/GPP Data Logger with LCD Display. Please read this user’s

manual carefully and thoroughly before using the instrument.

The OM-143 is a low-cost, compact, battery-powered thermo-

hygrometer capable of unattended logging (recording) of the

ambient temperature and relative humidity (RH) of an

environment for days, weeks or months. In addition, software

included with the product can also calculate and display

absolute humidity levels in units of grains per pound (GPP) or

g/kg. Also called mixing ratio, GPP is a more useful moisture

metric than RH to water damage remediators. Using RH

alone, a remediator might unknowingly introduce moist air—

with a low RH but a high GPP—during a job’s drying phase.

Data logging can be started or stopped by pushing a button

on the unit, eliminating the need to bring a laptop to the job

site. After a data log has been captured and stored, it can be

uploaded as a .txt file to any PC running the Windows®7 or

Windows®XP operating system after plugging the OM-143 into

one of the computer’s USB ports. The OM-143’s internal flash

memory is large enough to store 16,300 pairs of RH and

temperature readings.

Included with the product—which is slightly larger than a

thumb drive—is a mini-disc with the drivers needed to

interface the unit to the computer, as well as software that

can display a data log file as a table or graph and/or export it

to Microsoft Excel. Exporting to Excel is recommended for

sophisticated trending and analysis of humidity and

temperature data and easy detection of unexpected

excursions.

Windows®7 and Windows®XP are registered trademarks of Microsoft Corporation.

Applications for the OM-143 include:

• Water damage remediation—Because the OM-143 is

designed to be deployed and left in place over the

durion of the job, it is always in equilibrium with the

environment.

• Process control—The OM-143 enables, simplifies and cuts

the cost of environmental monitoring of office buildings,

greenhouses, food and equipment storage facilities,

wineries, freezers, shipping containers, HVAC/R

installations, computer rooms, labs, libraries, museums

and saunas.

• Electronics manufacturing—Alerts provided by the low-

humidity alarm function of the OM-143 can mitigate the

risk of damaging high-voltage static discharges.

KEY FEATURES

• One button starts/stops data logging without a PC

• Plug-and-play USB 2.0 interface; no need for cables,

cradles or docks

• Large storage capacity: 16,300 pairs of RH and

temperature readings

• 3-1/2-digit LCD displays real-time temperature and

humidity readings; also indicates device working status

and “memory full”

• Included software is used to set: Sampling time from

10 seconds to 12 hours; Hi/Lo alarm setpoints for

humidity and temperature; Temperature unit (°F or °C)

• Software also calculates and plots GPP and dew point and

wet bulb temperatures and displays data logs as time-

based graphs synchronized to your PC’s clock

• One-click exporting of logs to Excel or Word

• Long battery life (up to one year)

• Includes USB extension cable

• One-year warranty

SAFETY INSTRUCTION

Do not use the OM-143 in the presence of flammable or

explosive gases.

WHAT’S IN THE BLISTER PACK

The OM-143 comes in a blister pack that also contains

• One “1/2 AA” battery. Replacement batteries

(Part No. OM-EL-BATT) are available from Omega

• A disc with software drivers for Windows7 and Windows

XP computers, the ELusb V1.21.3 program for capturing

data logs and displaying them as curves, and a PDF of

this user’s manual

• A USB extension cable

• A hard copy of this user’s manual (inside the fold-over

card)

SETUP INSTRUCTIONS

INSTALLING/REPLACING THE BATTERY

The OM-143 uses a 3.6VDC “1/2 AA” Lithium-ion battery.

To open the battey compartment, use a paper clip or a

screwdriver with a fine point to push in the silver flange

showing through the small square hole in the rear of the unit

LATCH

(left photo on previous page). Push back the cover (middle

photo), remove the old battery (right photo) and insert a fresh

battery in the correct orientation. Then replace the cover,

pushing it forward until you feel and hear a click.

After you replace the battery, the LCD will “wake up” and

begin displaying real-time readings. If the MODE button is not

pressed within 60 seconds, the LCD will be automatically

powered off.

Note: If the battery is removed from a unit before it has been

set up from software or while it is recording, the unit must be

reconfigured before it can be reactivated. If it is not

reconfigured, the unit will remain in standby mode.

INSTALL SOFTWARE AND DRIVERS

1. Place mini-disc in tray of CD/DVD drive, shiny side down.

Close tray.

2. When the AutoPlay window appears, click on “Open folder

to view files using Windows Explorer.”

3. Windows Explorer will indicate that there are two “Files

Currently on the Disc”. One is actually a folder containing

a PDF of the OM-143 user’s manual (as well as PDFs of the

manuals for the OM-141 and OM-144—versions of the

OM-143 without an LCD and with an IR thermometer). Copy

the OM-143 manual to your computer’s hard drive for

permanent storage. The other file is a Windows Installer

Package (.msi file) named “ELusb_V1.23.1.msi”. Double-

click its icon.

4. A window titled “Welcome to ELUsb Installation Wizard”

will appear. Click Next to continue.

5. Within the Software License Agreement window that

appears next, click the I agree (T) box.

6. The next three windows advise that the ELusb application

will be installed in your computer’s C:\Program Files (x86)

folder in a new subfolder named <ELusb>, and that

shortcuts to the program will be created on your desktop

and Quick Launch bar. If you want to install the software

elsewhere, click Browse and choose another location

Within each window, after selecting either the default

location or another location, click Next(N) to continue.

7. When the “Preparing to Install” window detailing the

changes to made appears, click Install (I) to continue.

8. Before the installation begins, a User Account Control

window may appear and ask, “Do you want to allow

[ELusb V1.21.3msi] to make changes to this computer?”

Click Yes to continue.

9. The ELUsb Setup Wizard will now install the program on

your computer. On the next window that appears, click the

Completed (F) box.

10. At the bottom of the Device Driver Installation Wizard that

appears next, click Next to continue.

11. The next window to appear is a Windows Security

window. Click on “Install this driver software anyway”

to continue.

12. The next Device Driver Installation Wizard window will

advise you that an OM-141/143/144 driver from Omega

or Kecheng Laboratories was successfully installed and

that your device is now “Ready to use.” Click Finish to

continue.
