PC based application which allows the end user or OEM to create the translation files for the desired language selection. The translation files can
then be copied to the MC control system in order to provide a more accurate or desired translation.
10.5 Calibration
Each MC loop control is calibrated at the factory before shipment; however, they can be recalibrated in the field
with the use of proper calibration equipment. The user calibration offset provides the means for the end user
or OEM to simply apply an offset to the factory calibration. Typical reasons for applying this offset may include
the need to match a particular reference standard, to match the calibration to a particular transducer or sensor
or to remove long term drift in the factory set calibration.
To access calibration, select “Inputs” from the Calibrate menu. When more than one loop is installed, the
left/right navigation arrows will be provided at the top right of the screen. This allows the user to scroll through
each available loop and limit if installed.
Press the
Perform User Calibration Offset button to access the settings for applying an offset to the loop or
limit factory calibration. This is the recommended method of calibrating the inputs for users without special
calibration equipment, and is suitable for most applications.
Press the
Perform Manual Calibration button to begin the factory calibration procedure for the selected loop
or limit input. This option is NOT recommended for users with limited calibration experience. Special high
accuracy equipment is required to properly calibrate the inputs to factory standards. Improper calibration could
render the device inoperable and require it to be sent back to the factory for repair.
Prior to performing any calibration procedure, read the documentation carefully and understand the steps
required to perform calibration. The loop controls must be powered for a minimum of 30 minutes prior to
performing calibration in order to insure that they have warmed up and are at normal operating temperature.
