Product Description

• Easy to use

With the OMEGA CL540A Series you can check & calibrate all your thermocouple instruments.

• Take it without into the shop, plant or field

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

• Calibrate directly in temperature (°C & °F)

Stop carrying around a millivolt source and thermocouple tables. The OMEGA CL540A Series
works with the thermocouples you use including types J, T, E, K, R, S, B, N, G, C, D, L (J-DIN), U
(T-DIN) and Platinel II. Easily set any value quickly to within 0.1° with the adjustable digital
potentiometer “DIAL” plus store any three temperatures for instant recall with the DIAL switch.

• Compatible with all process instruments

Connect directly to the thermocouple inputs of smart transmitters, PLCs, DCS and multichannel
recorders and verify their outputs or displays.

SOURCE: Instantly output two preset thermocouple

temperatures by moving the DIAL switch to

These values can easily be changed to suit the
calibration requirements. The temperatures stored in
the HI and LO positions are also used for Auto

Approximately one to four hours of typical
operation remain before the OMEGA CL450A
will automatically turn off. To change the batteries;
remove the optional rubber boot, 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 conf

Connections

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

Plug thermocouple wires into the female
miniature thermocouple connector mounted in
the top end of the housing.

The OMEGA CL540A has two banana jacks
mounted in the top end of the housing. These
are not temperature compensated and are to be
used only for millivolt signals.

Note: All settings are remembered even with the
power off. Removing the batteries resets the

to factory defaults.

2) Select “SOURCE” with slide switch .

3) Connect a thermocouple wire (matching the type
of wire to sensor being simulated) with miniature
male T/C connector to the inputs of the device
being calibrated, making sure to check polarity.
Millivolt outputs (without cold junction) may be
connected with a copper (white) miniature T/C

Storing DIAL Outputs

STORING HI and LO DIAL Outputs

Choose this function to provide a simulated thermocouple signal into controllers, temperature
transmitters, indicators or any other input device that measure thermocouple sensors.

1) Stor e you r high (SPAN) output temperature by moving the DIAL switch to the HI position
and turn the DIAL knob until the desired temperature is on the display. Press and hold the
DIAL knob until STORED appears to store the value. Release the DIAL knob.

2) Stor e you r low (ZERO) output temperature by moving the DIAL switch to the LO position
and turn the DIAL knob until the desired temperature is on the display. Press and hold the
DIAL knob until STORED appears to store the value. Release the DIAL knob.

3) Insta nt ly o ut put your SPAN and ZER O te mp erature outputs by mo vi ng t he DIAL switch
between HI and LO. You may also select any third temperature output (such as mid-range) using
the SET position on the DIAL switch.
