12.0 EXPLANATION OF PROGRAM CODES

Various functions and features can be programmed to
enhance operation.  These programs are referred to as
“F Codes”.  Activate the “F Code”  programs by press-
ing and holding the 

F Button 

while  turning the shaft

until the desired number is displayed on the right dis-
play window.  User Codes are explained as follows:

F1

Toggle between normal and fine mode.

F3

Toggle switch between gram and ounce display

F7

Toggle switch of millimeter and inch for diameter
measurement

F12

The balancer has 4 counters that keeps track of total
number of cycles for a certain parameter.  The bal-
ancer will automatically cycle through the counters
after P12 is pressed.  The order of the counters are:

1. Display 

“Ctr  ALL”

 for one second.

Counter number of all spins.

2. Display 

“Ctr  CAL”

 for one second.

Counter number of spins since last calibration.

3. Display 

“Ctr  SrV”

 for one second.

Counter number of service spins.

4. Display 

“Ctr  USR”

 for one second.

Counter number of user spins.

F14

Shaft Calibration verification

F18

ALU-S mode (press balancing mode button to exit
and back to DYN mode)

F43

Read or reset operator counters, reads or allows re-
set of all four operators. (A, B, C, D)

F44

Read or reset productivity of user. Display counter
number of default user only.

F90
