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 th
