6-3 Thermocouple Calibration (Thermocouple/Resistance
Thermometer Input)
186
The E5CN/CN-U/AN/EN is correctly calibrated before it is shipped from the
factory, and normally need not be calibrated by the user.
If, however, it must be calibrated by the user, use the parameters for calibrat-
ing temperature input and analog input. OMRON, however, cannot ensure the
results of calibration by the user. Also, calibration data is overwritten with the
latest calibration results. The default calibration settings cannot be restored
after user calibration. Perform user calibration with care.
The input type selected in the parameter is used for calibration. The input
types are as follows:
Controllers with Thermocouple/Resistance Thermometer Multi-inputs
• Thermocouple:
• Infrared temperature sensor:
• Analog input:
• Platinum resistance thermometer: 5 types
Controllers with Analog Inputs
• Current input: 2 types
• Voltage input: 3 types
The new calibration data for each item is temporarily registered. It can be offi-
cially registered as calibration data only when all items have been calibrated
to new values. Therefore, be sure to temporarily register all items when you
perform the calibration. When the data is registered, it is also recorded that
user calibration has been performed.
Prepare separate measuring devices and equipment for calibration. For
details on how to handle measuring devices and equipment, refer to the
respective instruction manuals.
• Calibrate according to the type of thermocouple: thermocouple 1 group
(input types 5, 7, 11, 12, 15) and thermocouple 2 group (input types 6, 8,
9, 10, 13, 14, 16, 17, 18, 19, 20, 21, 22).
• When calibrating, do not cover the bottom of the Controller. Also, do not
touch input terminals/pins (terminals 4 and 5 on the E5CN, pins 1 and 2
on the E5CN-U, and pins 17 and 18 on the E5AN/EN) or compensating
conductors.
