General Information

Calibrate all your T/C & RTD Instruments

• Easy to use

With the Omega CL543B you can check and
calibrate all your thermocouple and RTD
instruments and measure temperature sensors.

• Take it into the shop, plant or field

Carry it without worry - it comes protected with a
rubber boot and rugged, low profile switches.
Easy to operate even in the dark areas of the
plant with the backlit display.

Calibrate T/C instruments to 0.1 & 0.01 °F & °C

•

The Omega CL543B works with the
thermocouples you use including types J, K, T,
E, R, S, B, N, G, C, D, L (J-DIN), U (T-DIN) and
P (Platinel II). Or calibrate from -13.0000 to
+80.0000 mV.

• Calibrate RTD instruments to 0.1 & 0.01 °F & °C

Stop carrying around a decade box and RTD
resistance tables. The CL543B works with the
RTDs you use including Platinum 10, 50, 100,
200, 500 & 1000 Ohm (alpha = 3850), Platinum
100 Ohm (alpha = 3902, 3916, 3926), Copper
10 & 50 Ohm, and Nickel 120 Ohm. Or calibrate
from 0.000 to 400.000 and 0.00 to 4000.00
Ohms.

Page 1

• Fast calibration with automatic output
stepping

Easily set any value quickly to within 0.1° or 0.01°
with the adjustable digital potentiometer “DIAL”
plus store any three temperatures for instant
recall with the EZ-CHECK™ switch. Choose
between 2, 3, 5, 11 steps and ramp to
automatically increment the output in 100%, 50%,
25%, 10% or 5% of span. Select step time from
5, 6, 7, 8, 9, 10, 15, 20, 25, 30 & 60 seconds.

• Compatible with ALL process instruments

No competitor’s calibrator is compatible with as
many process instruments! Connect directly to the
temperature inputs of transmitters, PLCs, DCS &
multichannel recorders to verify their outputs or
displays. RTD simulation works with older
instruments with fixed excitation currents and newer
multichannel instruments that switch the excitation
current between input channels.

• Perform Heat Treating Uniformity Surveys and
System Accuracy Tests

The Omega CL543B meets or exceeds the
requirement of AMS 2750 as a Field Test
Instrument.

• Measure thermocouple & RTD sensors

The Omega CL543B measures probes to 0.1 or

0.01 °C or °F. Secondary display shows the
millivolt or resistance value corresponding to the
sensor temperature. For T/Cs the cold junction

Page 2

temperature measured by the calibrator. For
RTDs the fixed or pulsed sensor current
outputted by the measuring instrument is
measured by the calibrator.

• Find problems with troubleshooting tools

Open thermocouples and thermocouples that
have high resistance indicating impending failure
are indicated by OPEN TC on the display.
Troubleshoot RTD sensor connections and find
broken wires with patented technology. Connect
your two, three or four wire RTDs and the
Omega CL543B automatically detects the
connections.

• Calibration Lab Accurate & Stable

The internal cold junction thermistor is accurate
to ±0.05°C and is traceable to NIST. The sensor
is thermally bonded to an isothermal mass
which includes brass blocks with screw
terminals for connection of bare thermocouple
wires along with a miniature thermocouple
connector for fast connections. The circuitry
uses an extremely stable voltage reference and
low drift components which make the CL543B
more accurate than most other handheld and
bench top thermocouple calibrators.

Connections

Simulating or reading thermocouples requires the use of
thermocouple or extension grade thermocouple wire.

Plug thermocouple wires into the miniature jack or place bare
thermocouple wires onto the brass block under the screws.

The Omega CL543B has two banana jacks (1+ & 2-) mounted
in the top end of the housing. These are not temperature
compensated and are to be used only for millivolt signals or
thermocouple signals with the cold junction turned off.

Simulating or reading RTDs uses copper wire.

Plug 2, 3 or 4 wires into the corresponding jacks on the
calibrator. For RTD source the Omega CL543B simulates the (+)
RTD from jacks 1 & 4 and the (-) RTD from jacks 2 & 3.

When reading an RTD sensor the Omega CL543B uses
patented circuitry to automatically detect if 2, 3 or 4 wires are
connected. This is helpful to troubleshoot sensor connection
(see Troubleshooting an RTD Sensor).

Operating Instructions

FIELD & BENCH USE

Omega CL543B comes with a carrying case designed for
hands-free operation and a rubber boot with a built-in tilt stand.
The Omega CL543B is held in the case by elastic straps for use
with the carrying case open. The tilt stand is easily raised by
pulling the stand until it locks into place.

Operating Instructions

CHANGING BATTERIES

Low battery is indicated by a battery symbol on the display.
Approximately one to four hours of typical operation remain before
the Omega CL543B will automatically turn off. To change the
batteries remove the rubber boot and remove the battery door
from the back of the unit by sliding the door downward. This allows
access to the battery compartment. Replace with four (4) “AA” 1.5V
batteries being careful to check the polarity. Replace the battery
door and replace the boot. All stored configuration options (T/C
Type, EZ-CHECK Memories, etc.) are reset to factory settings
when the batteries are removed.
Note: Alkaline batteries are supplied and recommended for
typical battery life and performance. Optional rechargeable
batteries (charged externally) are available.

STORING HI and LO EZ-CHECK Source Outputs

Speed up your calibration by storing Span & Zero output setting
for instant recall with the EZ-CHECK switch.

1) Store your high (SPAN) output temperature by moving the

EZ-CHECK switch to the HI position and turning the EZ-Dial
knob until the desired output value is on the display. Press
and hold the EZ-Dial knob until STORED appears to store
the value. Release the EZ-Dial knob.

2) Store your low (ZERO) output value by moving the EZ-CHECK

switch to the LO position and turning the EZ-Dial knob until
the desired output value is on the display. Press and hold the
EZ-Dial knob until STORED appears to store the value.
Release the EZ-Dial knob.

3) Instantly output your SPAN and ZERO output settings by

moving the EZ-CHECK switch between HI and LO. You may
also select any third output setting (such as mid-range) using
the SET position on the EZ-CHECK switch.

wires are connected using a patented circuit and indicates each
wire that is connected. Any wires that are not connected or
broken are indicated by the CL543B. This is useful for

Troubleshooting RTD Instruments

When you are having an issue where an instrument won't read
an RTD sensor or you don't know if the calibrator is connected
properly the Omega CL543B has a function to measure and
display the fixed or pulsed sensor (excitation) current that the
instrument uses to measure the resistance of the RTD sensor.

Double click the
then turn the e DIAL KNOB to move to the second menu page
so the word DISPLAY appears at the top of the menu.
Turn the
cursor is pointing at SENSOR mA. Press the e DIAL KNOB to
toggle SENSOR mA ON.

Disconnect all sensor wires from the devices to be calibrated and
connect the Omega CL543B to the inputs of the device using 2, 3 or
4 wires. The sensor current generated by the instrument will be
indicated on the display followed by the word FIXED or PULSE. Older
single channel RTD instruments used a constant (fixed) current
source to measure an RTD sensor. Smart transmitters, multichannel
recorders and PLC or DCS input cards switch the current source
sequentially through the channels which is seen as an intermittent
(pulsed) current.

Troubleshooting RTD Sensors

When troubleshooting a problem with an RTD input it is useful to
check that the sensor and the wiring to the instrument is
operating properly.

The Omega CL543B automatically detects 2, 3 and 4 wire RTD
connections with a patented circuit. It will also display the
connections on the display and indicate when there is a missing
connection due to a loose connector, corrosion or a broken wire.

Here is an example of the CL543B reading a
sensor with all 4 wire connected.

Here is an example where connections are
made to a 4 wire sensor and the CL543B
indicates that only Wires 1, 2 & 4 are connected.
There may be a loose connection or a break in
wire 3 somewhere between the sensor and the
CL543B.
