P84 EMPTY SHAFT CALIBRATION PROCEDURE
NOTE: THIS PROCEDURE CAN ONLY BE DONE USING THE
PRUEFROTOR.
1. Hold the P key and turn Diameter funtion knob until “P” “84” is dis-
played and release the P key. The display changes to “CAL” “SHF”
for one second.
2. Then it displays “SPN” “1“.
3. Spin shaft with Pruefrotor only. (Figure 3-13)
The board displays the following information.
• Displays “SPN” “UP“ when shaft reaches 60 RPM.
• Displays “COA” “ST“ with a beep sound when shaft speed is over
120 RPM.
• Displays “CAL” “ 1” when the speed drop down to 119 rpm. At
this moment the machine is taking data and doing calculation work.
After taking data, shaft is automatically stopped and displays “SHF”
“FIN” for one second. The machine displays the shaft resident unbalances in fine mode. The fine mode
LED indicator is automatically on.
• By pressing STOP key to exit P84 and return to idle state. The fine mode LED indicator is automatically
turned off
P85 COPY CONTENTS OF MAIN PCB TO ENCODER, ONLY AVAILABLE IN INITIALIZATION.
When an Encoder PCB is replaced and on initial power up the unit will display “P85”. The technician needs to
simply press the <P> key to transfer the calibration factors from the Main PCB over to the new Encoder.
P86 COPY CONTENTS OF ENCODER TO MAIN PCB, ONLY AVAILABLE IN INITIALIZATION.
When a Main PCB is replaced and on initial power up the unit will display “P85”. The technician needs to press
the <STOP> key to toggle the display to “P86”. Once the display changes to P86 the technician should press
the <P> key to transfer the calibration factors from the Encoder to the Main PCB.
P90 MATCH BALANCE
Matches the tire to the wheel. See operators manual for detailed information.
P91 OPTIMIZATION
See operators manual for details.
P 95 CLEAN & RESET EEPROM 1 & 2
Care should be taken before running this function. All information in the EEPROM will be lost including manu-
facture calibration which can not be reversed once performed. However this function can be very useful if data is
corrupted on the EEPROM’s. Performing this function can be much quicker than re-flashing the software.
1. Press and hold the <P> key while turning the Diameter/Function Knob until “P” “95” is displayed. The
machine displays “CLN EEP” immediately. The user can press the <STOP> button at anytime before step
5 to abort this procedure.
2. Press P button, the balancer displays “ 1 1 1 “.
3. Press P button again, the balancer displays “ 2 2 2 “.
4. Press P button again, the balancer displays “ 3 3 3 “.
5. If user press P button again, balancer displays “ CLN EEP” and erases all information in the EEPROM and
resets the machine. All factory calibration procedures are now required.
