C-4 Calibration
Prepare separate measuring devices and equipment for calibration. For details
on how to handle measuring devices and equipment, refer to the respective
instruction manuals.
User Calibration Calibrating Input
The 900-TC8, 900-TC16, and 900-TC32 are correctly calibrated before they
are shipped from the factory, and normally need not be calibrated by the user.
If, however, they must be calibrated by the user, use the parameters for
calibrating temperature input and analog input. Rockwell Automation,
however, cannot ensure the results of calibration by the user. Also, the factory
calibration data is overwritten with the latest user calibration results. The
default calibration settings CANNOT be restored after user calibration.
Perform user calibration with care.
When the user calibrates the Bulletin 900 Controller, the Input Type currently
selected in parameters is calibrated.
The following 26 Input Types can be calibrated:
• Thermocouple: 16 types
• Non-contact temperature sensor: 4 types
• Analog input: 1 type
• Platinum resistance thermometer: 5 types
Controllers with Analog Inputs (900-TC8 and 900-TC16):
• Current input: 2 types
• Voltage input: 3 types
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
calibrate the Bulletin 900 Controller.
When calibration data is registered, it is registered regardless of whether or not
the Bulletin 900 Controller has been calibrated by the user.
Prepare separate measuring devices and equipment for calibration. For details
on how to handle measuring devices and equipment, see the respective sensor
manufacturer’s instruction manuals.
