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, and
0.1/1°.
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.
