1.6 About Calibration
The E5CKĆT controller is calibrated before shipment from the factory. So,
the user need not calibrate the E5CKĆT controller during regular use.
However, if the E5CKĆT 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 reĆ
sults of calibration will not be assured.
Also, note that calibration data is updated to the latest value each time
that the E5CKĆT controller is calibrated. Calibration data set before shipĆ
ment 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
E5CKĆT is provided with the following four calibration parameters:
Ă• Thermocouple
Ă• Platinum resistance thermometer
Ă• Current input
Ă• Voltage input
Two parameters are provided for thermocouple and voltage input.
Transfer output also can be calibrated when the communications unit
(E53ĆCKF) is added on.
When calibrating each item, the calibration data is temporarily regisĆ
tered. This data can be registered as final calibration data only when all
items have been newly calibrated. So, all items must be temporarily regisĆ
tered when the E5CKĆT controller is calibrated.
When registering data, information regarding whether or not calibration
has been carried out is also registered.
To calibrate these items, the user must prepare separate measuring deĆ
vices and equipment. For details on handling these measuring devices and
equipment, refer to the respective manuals.
For details, see Chapter 7 Calibration.
