Button Operation

The “MODE” and “SET” buttons located of the front display of your meter are
activated by waving or taping the magnetic stylus included with your unit above
or onto the keypad button symbol on the front meter label.

Mode Button Operation – To activate the “MODE” button, place the tip of the
magnetic stylus over the “MODE” button and hold for three seconds until the
unit enters the “MODE” menu. Then move away the magnetic stylus. Each time
the magnetic stylus is again placed near the “MODE” button the meter will step
through each parameter.

“SET” Button Operation - The “SET” button has two primary functions.
Independently the button is used to turn the backlighting on. To activate the
backlight, place the tip of the magnetic stylus over the “SET” button and hold for
three seconds until the backlighting turns on. The backlighting will remain on
for the amount of time you selected during the setup and configuration process.

NOTE:

If you selected “Always Off” when setting the meter up, then
the “SET” button will not turn the backlighting on from the
front keypad.

When in the “MODE” menu, the “SET” button is used for the following:

1. To reset the MIN, MAX, or AVG values to the current temperature reading.
All three are reset simultaneously, from any one of the three screens, MIN,
MAX, or AVG.

2. To silence the High or Low alarm, when in the “HAL” or “LAL” screen and
the alarm is configured for “Latching”. This will cause the display to stop
blinking, however, the alarm output will remain activated until the alarm
condition clears.

3. To turn the wireless transmitter “On” or “Off” while in the “WRLS” screen.

4. To select units of measure while in the “UNIT” screen.

Optional Wireless Transmitter Operation

TRANSMITTER ANTENNA

Section 6 – Optional Wireless Transmitter Operation

6.1 Introduction

Compared to a wired connection, a wireless meter provides much simpler
installation. Based on the physical principle of the propagation of radio
waves, certain basic conditions should be observed. The following simple
recommendations are provided to Insure proper installation and correct
operation of your wireless meter.

6.2 RF Communication Basics

Your wireless transmitter sends wireless transmissions to a receiver. The receiver

checks the incoming data for accuracy and processes this data for use by the
measurement software on your PC. Radio signals are electromagnetic waves,
hence the signal becomes weaker the further it travels. While radio waves can
penetrate some solid materials like a wall, they are dampened more than when a
direct line-of-sight between the transmitting and receiving antenna exist.

6.3 Basic System Overview

6

A basic wireless temperature system is comprised of only two main components;
a signal conditioner with a built-in battery powered 2.4GHz radio transmitter,
and a USB powered 2.4GHz radio receiver.

Installation

When installing your meter it is important to position the unit in such a way as
to optimize the antenna location within what’s known as the “Fresnel Zone”.

The Fresnel Zone can be thought of as a football-shaped invisible tunnel between
two locations that provides a path for RF signals between your meter and your
receiver.

RECEIVER

FRESNEL ZONE

ANTENNA

Figure 6-1. Fresnel Zone

6-1

6

Operational Wireless Transmitter Operation

In order to achieve maximum range, the football-shaped path in which radio
waves travel must be free of all obstructions. Obstacles in the path (especially
metal) will decrease the communication range between your meter and receiver.
Also, If the antennas are mounted just barely off the ground, over half of the
Fresnel zone ends up being obstructed by the earth resulting in significant
reduction in range. To avoid this problem, the antennas should be mounted high
enough off of the ground so that the earth does not interfere with the central
diameter of the Fresnel zone.

It is important to understand that the environment may
change over time due to new equipment or machinery being
installed, building construction, etc. If new obstacles exist
between your meter and receiver, the devices can be raised
on one end or on both ends to clear the Fresnel Zone of
obstructions.

NOTE:

CAUTION:

Installing your meter in an application were the unit will
be exposed to ambient temperatures above or below the
operating limits specified in this manual will damage your
unit and cause the unit to malfunction and produce incorrect
operation.

NOTE:

Your meter has been shipped to you with a standard
approved antenna. Use of any other antenna than what’s
supplied with your meter will void all FCC, IC and CE
regulatory compliance.

Environment

Omega’s wireless end devices and receiver units have been designed to be fixed
mounted and operated in a clean and dry indoor environment. Care should be
taken to prevent the components of your wireless system from being exposed to
moisture, toxic chemicals and extreme cold or hot temperature that are outside
the specifications listed in this manual.

6-2

The following is a list of basic good practice you should apply when operating
your wireless system.

• Never operate your wireless device or receiver outside the recommended

environmental limits specified in this manual.

• Never operate your wireless end device or receiver in flammable or explosive

environments.

• Never use your wireless end device or receiver in medical, nuclear or other

dangerous applications where an interruption of readings can cause
damage or harm.

• Never operate your end device or receiver with any other battery or power source

than what’s specified in this manual or on the battery compartment label.

• No co-location with other radio transmitters is allowed. By definition,

co-location is when another radio device or it’s antenna is located within
20 cm of your end device and can transmit simultaneously with your end
device.

• Never install end devices within 20 cm or less from each other.

• Never use your end device as a portable device. Your unit has been designed

to be operated in a permanent installation.

• Never install and/or operate your end device closer than 20 cm to nearby

persons.

• Never operate your end device with any other antenna than what is supplied

or listed here in this manual for approved use.

6.4 Transmit Rate vs. Battery Life

Operational Wireless Transmitter Operation

6

Many factors such as ambient temperature conditions and transmitting rate can
have a big effect on the life of the battery used in your meter. Transmitting data
places a big demand of the battery in your unit. The transmit rate is the single
most contributing factor in the life of the battery. The slower the transmit rate you
set, the longer the battery in your device will last. The tables and graphs below
give some estimates on how long the battery should last vs. the transmit rate you
selected when you setup your meter under normal operating conditions.

6.5 Wireless Transmitter Setup

After connecting the USB cable and running the configuration software as
outlined in Section 3, you will complete the following steps to configure your

wireless transmitter before placing the unit into operation. You will be using the

configuration software utility that you installed onto your PC in Section 3. If
you have not installed the configuration software utility you should do so now.

During this procedure you will be setting the following parameters in your
transmitter.

RF Channel

This setting determines the operating channel on which RF connections are
made between the transmitter and receiver. The transmitter must be set to the
same channel as the receiver in order for them to communicate.

Network ID

This sets the ID of the Network that the transmitter will be joining. It must
match the setting of the receiver in order for them to communicate.

Receiver Address

Operational Wireless Transmitter Operation

6

This sets a unique address number for your receiver. Later, when you set up
your receiver you will again set the same number to receive readings from
the corresponding transmitter unit(s). Each receiver must be set for a different
number for your system to operate correctly.

NOTE:

If you will be using more than one receiver unit in your area
it is important to set the transmitter address numbers to be
a corresponding number in your TC-Central software. See
Examples below.

For the first receiver:

Set the address on your transmitters to 101, 102, 103, 104, etc. Then set the
address in your TC-Central software to match.

For the second receiver:

Set the channels on your transmitters to 201, 202, 203, 204, etc. Then set the
address in your TC-Central software to match.

This numbering scheme can be expanded to match the number of receivers you
are using.

Gauge Address

This sets a unique address number into your transmitter. Later, when you set up
your measurement software you will use this address setting to receive readings
from the corresponding unit(s). Each transmitter must be set for a different
address for your system to operate correctly.

Wireless Transmission Rate

This will program your device to transmit 1 data reading to your receiver at a
specified time interval. Available settings are 2, 3, 4, 5, 10, 15, 30, 45, 60, 75, 90, 105
or 120 seconds.
