Operating Instructions

(Shown without optional boot)

Product Description

• Easy to use

With the CL540A/CL540ZA 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 PIECAL CL540A/CL540ZA
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 HI/SET/LO
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.

q HI/SET/LO SWITCH

SOURCE: Instantly output two preset thermocouple

temperatures by moving the HI/SET/LO switch to the
“LO” position or “HI” position.
checks select the “DIAL” position. The Omega
CL540A/CL540ZA will remember the last “DIAL”
value, even with the power off.
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
Stepping.

For fast three point

w SOURCE/OFF Switch

Select “SOURCE” to output in °C, °F, or millivolts.

e KNOB

SOURCE: Turn the knob to adjust the output
level. Turn clockwise to increase the output,
counter clockwise to decrease the output in 0.1°
steps at a time. Push down and turn the knob for
faster dialing.
Press and hold the knob for two seconds to store
desired HI/LO points in SOURCE mode.

Double click the knob to get into the Omega
CL540A/CL540ZA Configuration Mode. Use
configuration to select °C or °F, T/C Type
(CL540ZA Only) and Auto Off On/Off.

CHANGING BATTERIES

Low battery is indicated by “BAT” on the display.
Approximately one to four hours of typical
operation remain before the CL540A/CL540ZA
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 configuration options (T/C Type, HI/SET/
LO Memories, etc., are reset to factory settings
when the batteries are removed.

Note: Alkaline batteries are supplied and
recommended for maximum battery life and
performance.

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 CL540A/CL540ZA 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.

TEMP UNITS - pressing the knob will toggle
between °C and °F.

T/C ­CL540A: pressing the knob will toggle bet ween
the factory configured T/C Type and mV.

CL540ZA: pressing the knob will cycle through
T/C types J, T, E, K, R, S, B, N, G, C, D, L
(J-DIN), U (T-DIN), Platinel II and mV.

AUTO OFF - If AUTO OFF is ON, the unit will
turn off after 30 minutes of inactivity to save
battery life. If AUTO OFF is OFF the unit will stay
on until the POWER SWITCH is moved to the off
position.

Note: All settings are remembered even with the
power off. Removing the batteries resets the
values to factory defaults.

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

1) Disconnect the thermocouple sensor from the
device to be calibrated.

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
connector or the banana jacks with copper wire.

The output is adjusted in 0.1° (or 0.001 mV)

STORING HI and LO 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) Store your high (SPAN) output temperature by moving the HI/SET/LO switch to the HI position
and turn the
knob until STORED appears to store the value. Release the knob.

2) Store your low (ZERO) output temperature by moving the HI/SET/LO switch to the LO position
and turn the
STORED appears to store the value. Release the knob.

3) Instantly output your SPAN and ZERO temperature outputs by moving the HI/SET/LO switch
between HI and LO. You may also select any third temperature output (such as mid-range) using
the SET position on the HI/SET/LO switch.
