6-2 User Calibration
6-2-1 Calibrating Inputs
When calibration has been performed after purchase, the user calibration
information shown in the following illustration will be displayed when moving to
the calibration level.

6-2-2 Registering Calibration Data
A dot is displayed.
The E5@N-H 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 calibrating
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, Analog Universal
Inputs
Thermocouple: 19 types
Analog input: 5 types
Platinum resistance thermometer: 6 types
The new calibration data for each item is temporarily registered. It can be officially
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.
6-3 Thermocouple Calibration (Thermocouple/Resistance
Thermometer Input)
Calibrate according to the type of thermocouple: thermocouple 1 group
(input types 5, 7, 11, 12, 15, 19, 20) and thermocouple 2 group (input
types 6, 8, 9, 10, 13, 14, 16, 17, 18, 21, 22, 23).
When calibrating, do not cover the bottom of the Controller. Also, do not
touch input terminals/pins (terminals 4 and 5 on the E5CN-H, and pins 19
and 20 on the E5AN/EN-H) or compensating conductors.
