The E5EK-T controller is calibrated before shipment from the factory.
So, the user need not calibrate the E5EK-T controller during regular
use.
However, if the E5EK-T controller must be calibrated by the user, use
the parameters provided for the user to calibrate temperature input,
analog input (voltage, current) and transfer output. In this case, note
that the results of calibration will not be assured.
Also, note that calibration data is updated to the latest value each time
that the E5EK-T controller is calibrated. Calibration data set before
shipment from the factory cannot be returned to after calibration by
the user.
The input type selected in parameters is the item to be calibrated. The
E5EK-T is provided with the following four calibration parameters:
• Thermocouple
• Platinum resistance thermometer
• Current input
• Voltage input
Two parameters are provided for thermocouple and voltage input.
Transfer output also can be calibrated when the communications unit
(E53-AKF) is added on.
When calibrating each item, the calibration data is temporarily regis-
tered. This data can be registered as final calibration data only when all
items have been newly calibrated. So, all items must be temporarily
registered when the E5EK-T controller is calibrated.
When registering data, information regarding whether or not calibra-
tion has been carried out is also registered.
To calibrate these items, the user must prepare separate measuring de-
vices and equipment. For details on handling these measuring devices
and equipment, refer to the respective manuals.
For details, see Chapter 7 Calibration.
