6.11 REFERENCE CALIBRATION
At this point in the calibration program the CONFIGURATION calibration has been completed. Three situations may exist.
a)
You have completed what you need to do and wish to return the controller to use. Push the PARAM key and
proceed to section 6.16.
b)
The controller will not advance when you push the PARAM key. Proceed with the following instructions. This
occurs usually when calibrating after a DATA LOST/PLEASE CAL.
c)
You wish to perform a REFERENCE calibration. Proceed with the following instructions.
CAUTION:
ENTRY INTO THE REFERENCE CALIBRATION ROUTINE WITHOUT PROPER CALIBRATION
EQUIPMENT MAY ERASE THE FACTORY CALIBRATION. DO NOT PROCEED WITH THESE
INSTRUCTIONS UNTIL YOU ARE PROPERLY PREPARED.
REFERENCE calibration refers to the procedure for calibrating the controller to an external input reference source. Before
starting a reference calibration you must be at one of these displays.
