Push the PARAM key andproceed to section 6.16.b)The controller will not advance when you push the PARAM key. Proceed with the following instructions. Thisoccurs 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 CALIBRATIONEQUIPMENT MAY ERASE THE FACTORY CALIBRATION. DO NOT PROCEED WITH THESEINSTRUCTIONS UNTIL YOU ARE PROPERLY PREPARED.REFERENCEcalibration refers to the procedure for calibrating the controller to an external input reference source. Beforestarting a reference calibration you must be at one of these displays.HI SPANORHI VALXXXXXXIf you are not at one of these displays and wish to do a REFERENCE calibration push the PARAM DISPLAY key until "CALCOMPLETE" appears. Then push the LAST key once.A security code protects the reference calibrationprocedures. To enter the reference calibration mode pushthe two keys indicated in Figure 6-3 simultaneously.CAUTION:ALLOW AT LEAST A 20 MINUTE WARMUPBEFORE ANY REFERENCE CALIBRATIONIS ATTEMPTED.There are three stored calibration routines. The controller will automatically display the correct instructions for yourapplication.6.12Thermocouple Input calibration6.13RTD Input calibration6.14Process Input calibrationECLIPSE INSTRUMENTATION DIVISION(page 3 - 1121)FIGURE 6-3
