7 User Calibration
7-1 User Calibration
The E5@C is correctly calibrated before it is shipped from the factory. Normally it does not need to be
calibrated by the user.
If, however, it must be calibrated by the user, use the parameters for calibrating temperature input and
analog input. OMRON, however, cannot ensure the results of calibration by the user. Also, calibration
data is overwritten with the latest calibration results. The default calibration settings cannot be restored
after user calibration. Perform user calibration with care.
Calibrating Inputs
The input type selected in the parameter is used for calibration. The input types are as follows:
• Thermocouple:
• Infrared temperature sensor:
• Resistance thermometer:
• Current input:
• Voltage input:
*1 There are four types of voltage inputs for E5CC-U Digital Controllers manufactured in May 2014 or later
(version 2.2 or higher).
Registering Calibration Data
The new calibration data for each item is temporarily registered. It can be officially registered as
calibration data only when all items have been calibrated to new values. Therefore, be sure to
temporarily register all items when you perform the calibration. When the data is registered, it is also
recorded that user calibration has been performed.
Prepare separate measuring devices and equipment for calibration. For details on how to handle
measuring devices and equipment, refer to the respective instruction manuals.
Wiring the E5@C-B (Models with Push-In Plus Terminal Blocks)
When connecting two wires to one terminal to calibrate the E5@C-B, do so as given below.
• Using Stranded Wire
Use AWG24 to AWG20 (0.25 to 0.5 mm
• Using Twin Ferrules
Use AWG22 to AWG18 (0.5 to 0.75 mm
Attach the two wires to the twin ferrule first, and then connect the ferrule to the terminal.
