The E5EK DRT controller is calibrated before shipment from the factory.
So, the user need not calibrate the E5EK DRT controller during regular
use.
However, if the E5EK DRT controller must be calibrated by the user, use
the parameters provided for user to calibrate temperature input, analog
input (voltage, current). 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 the
E5EK DRT 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
E5EK DRT is provided with the following four calibration parameters.
Thermocouple
Platinum resistance thermometer
Current input
Voltage input
Two parameters are provided for thermocouple, platinum resistance ther
mometer and voltage input.
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 E5EK DRT 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 chapter 7 Calibration.
