The E5CK controller is calibrated before shipment from the factory. So,
the user need not calibrate the E5CK controller during regular use.
However, if the E5CK 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
E5CK 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
E5CK 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---CKF) 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 regis-
tered when calibrating the E5CK controller.
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
devices and equipment. For details on handling these measuring devices
and equipment, refer to the respective manuals.
For details, see 4.5 Calibration (page 4---11).
