Page 11: Connecting A Thermocouple
CONNECTING A THERMOCOUPLE Use the correct thermocouple type for your instrument setting. Using an incorrect thermocouple type will result in erroneous readings. Thermocouples are colour coded by type using the North American ANSI Color Code as follows: TYPE COLOR Black Yellow Blue Purple... - Page 12 Thermocouple wiring polarity must be correct. If readings decrease as the temperature increases, the thermo- couple wires may be reversed. The red wire is negative for thermocouple wires manufactured in North America. If no probe is connected the display will read “open”. Thermocouples are sensitive at the tip or measuring junction.

Page 20: Calibration Screen
CALIBRATION SCREEN The thermometer is factory calibrated and does not require calibration before use. The Calibration function allows single- point calibration of the meter at 0°C (32°F) to compensate for thermocouple offset error. It is NOT necessary to perform a field calibration to obtain specified meter accuracy. - Page 21 Select calibration method by pressing F1 and the ▲ or ▼ keys. Then select the channel you with to calibrate the ▲ or ▼ keys . Offset Calibration Use the ▲ or ▼ keys to adjust the value to match known temperature standard. Press F1 to accept.
- Page 22 Slope Calibration Use the ▲ or ▼ keys to adjust the value to match known temperature standard. Press F1 to accept. Then move to second temperature point using the ▲ or ▼ keys and repeat. Match Calibration Use the ▲ or ▼ keys to adjust the value to match T1 readings and T2 readings.
