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. - Page 8 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.

Page 15: Calibration Procedure
5.0 CL3152A Calibration Procedure Note: The following calibration procedure should be performed only by qualified technicians who have access to the items as following items: Equipment: 1) A very accurate millivolt source. 2) A TRC III ICE Point Reference or ice bath with type Input Funtion "Calibration"... - Page 16 "Simulated Output" Test 1. Turn the knob "COARSE" right to the end, knob of RANGE turn right to the last two position, press "TYPE" key to select "TYPE-E", if display does not show "OL" then adjust VR4 slowly to make display ="OL" (Note: Take care not to adjust VR4 too far).
- Page 17 CL3512A CALIBRATION PROCEDURES Note: The following calibration procedure should perform only by qualified technicians who have access to the items as following. Equipment: The class of calibrator had better 10 times greater than the measured meter. INPUT FUNTION CALIBRATE 1. Before turn on the meter, turn the RANGE knob to position "INPUT" and then move short pin to upper two pin of J5 which is at the left upper of PCB.
