The E5AK controller is calibrated before shipment from the factory. So,
the user need not calibrate the E5AK controller during regular use.
However, if the E5AK controller must be calibrated by the user, use the
parameters provided for user to calibrate temperature input, analog
input (voltage, current) and transfer output.
Also, note that calibration data is updated to the latest value each time
the E5AK 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 the parameter is the item to be calibrated.
The E5AK 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 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 calibrating the E5AK controller.
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
devices and equipment. For details on handling these measuring devices
and equipment, refer to the respective manuals.
For details, see Chapter 7 Calibration.
