CT-3 OPERATING MANUAL 1.0 GENERAL DESCRIPTION 1.1 The CT-3 is a simple device that simulates thermocouple signals so that the accuracy of a thermocouple thermometer can be checked instantly, without waterbaths. 1.2 The regular CT-3 is designed for use with type T thermocouple thermometers and has fixed electrical signals corresponding to five temperatures: 0.0 , 15.0 , 37.0 , 45.0 and 50.0 C. It is possible to order CT-3 with other settings.
thermometer under test, continue the calibration check. If they do not, the thermocouple thermometer may require recalibration. Note: ensure that the mercury thermometer is viewed perpendicular to the tip of the mercury column to avoid parallax effects. 3.4 Press the grey ON ADJUST button on the CT-3. While holding down this button, turn the ADJUST knob until the thermocouple thermometer displays 25.0 C (77.0 F) 3.5 Continue to hold down the grey button. Press in turn the 0.0 , 15.0 , 37.0 , 45.
