It is the policy of OMEGA to comply with all worldwide safety and EMC/EMI regulations that apply. OMEGA is constantly pursuing certification of its  
products to the European New Approach Directives. OMEGA will add the CE mark to every appropriate device upon certification.  
The information contained in this document is believed to be correct but OMEGA Engineering, Inc. accepts no liability for any errors it contains, and

1.0 Introduction  
The OMEGA® CL3512A calibrator/thermometer is two meters in one. The  
CL3512A simulates type J/K/T/E thermocouple signals. Each signal is  
adjustable by using the coarse and fine dials. The CL3512A can also be used  
as a dual type J/K/T/E thermocouple input thermometer. Features include a  
large 3½ digit display with backlighting and display selections of HOLD, °C/°F,  
and0.1/1°.  
The source mode of the CL3512A simulates the thermocouple output to check  
the operation of  
a
thermocouple meter and make rough calibration  
adjustments. A more accurate calibrator would be required for calibration of  
thermocouple meters to specify tolerances.  
1.1 Safety Information  
It is recommended that you read the safety and operation instructions before  
using the thermometer.  
WARNING  
To avoid electrical shock, do not use this instrument when working  
voltages at the measurement surface over 24V AC or DC.  
WARNING  
To avoid damage or burns, do not make temperature measurement  
in microwave ovens.  
CAUTION  
Repeated sharp flexing can break the thermocouple leads. To prolong  
lead life, avoid sharp bends in the leads, especially near the connector.

2.2 Descriptions of Buttons and Switches  
/
Buttons  
Temperature is displayed in either degrees Celsius(°C) or degrees  
Fahrenheit(°F). When the thermometer is turned on, it is set to the  
temperature scale that was in use when the thermometer was last turned off.  
To change the temperature scale, press the °C or °F key.  
Button  
Press “ ” button to toggle the on and off backlight. The backlight will  
switch-off automatically after 37 seconds.  
Button (HOLD Mode)  
Press the HOLD key to enter the Data Hold mode, the “HOLD” annunciator is  
displayed. When HOLD mode is selected, the thermometer will hold the  
present reading and stop all further measurements.  
Pressing the HOLD key again will cancel HOLD mode causing the  
thermometer to resume taking measurements.  
Button (K/J/T/E Input Thermocouple Type Selection)  
The TYPE key allows for selection of J, K, E or T thermocouple types as either  
the input or simulated output. To select thermocouple type press type key  
once. Unit will briefly show 1888 and beep and then the type of thermocouple  
selected will be indicated on the left hand side of the display. Continue  
pressing the type key to step through the thermocouple types until desired  
type is indicated.

Input Selections  
The input selection indicates which input is selected; T1 thermocouple, T2  
thermocouple or the difference between the two thermocouples (T1-T2).  
When the thermometer is turned on, it is set to the temperature input that was  
in use when the thermometer was last turned off.  
Selector Switch  
The circular selector switch is used to turn the unit off () or to select Reading  
Mode (Input) or Simulation Mode (Output). There are nine selector switch  
positions under output which provide rough adjustment of the simulated  
output.  
Adjust  
Course and fine adjustment Dials are used in Simulation Mode to allow a  
particular simulated temperature to be selected once the output has been  
adjusted close to the desired temperature using the selector switch.

2.3 Read Mode Procedure  
1. Plug Thermocouple Sensor into input T1 and/or T2.  
2. Turn selector switch to Input.  
3. Select proper thermocouple type (J, K, T or E) using type button.  
4. Press T1 button to read thermocouple connected to input T1.  
Press T2 button to read thermocouple connected to input T2.  
Press T1-T2 if difference between T1 and T2 is to be read.  
5. To Hold reading press HOLD button. To resume making measurements  
press HOLD again.  
Note: Unit will display -OL if input is out of range or thermocouple is broken  
or not connected to proper input.  
To save battery life, CL3512A will turn off automatically if no is key is pressed  
for 90 minutes.

2.4 Source Mode Procedure (Calibration Simulation)  
1. Turn CL3512A on by turning selector switch to any one of the output  
selector positions.  
2. Press T1 button.  
3. Select thermocouple type (J, K, T or E) using type button.  
Select °C or °F using °C or °F buttons.  
4. Plug proper type of thermocouple wire into either one of the two output  
connectors. (SMP male connector required)  
5. Attach the other end of the thermocouple wire to the instrument being  
tested/calibrated.  
6. Move the output range switch to the temperature value close to the desired  
simulated value.  
Note: There are 9 temperature range switch positions arranged from left to  
right representing low to high temperatures.  
The display will read -OL if the output voltage for the meter is higher  
than the maximum voltage for that particular thermocouple type. For  
type T this will be in the highest 4 positions, type K in the highest 3  
positions, type J in the highest 2 positions, and type E in the highest  
position only.  
7. Adjust course and/or fine adjustment dial until desired temperature is  
displayed on CL3512A.  
8. Instrument under test should read same temperature as CL3512A. If not  
adjust instrument under test or have recalibrated.  
9. Repeat steps 6-8 at different temperatures as needed.

3.0 Operator Maintenance  
WARNING  
To avoid possible electrical shock, disconnect the thermocouple  
connectors from the thermometer before removing the cover.  
Battery Replacement  
Power is supplied by a 9 volt “transistor” battery. The “ ” appears on the  
LCD display when replacement is needed. To replace the battery, remove the  
two screws from the back of the meter and lift off the battery cover. Remove  
the battery from battery contacts.
