CAUTION
Make sure power is off before attaching dip-clip to U1 chip. Failure to
do so could result in damage to auto-scaler.
h. Attach dip-clip to U1 chip on main logic PC board.
i.
Attach positive lead from encoder calibrator to pin 3 on U1 chip.
Attach negative lead to pin 12.
Turn B/ACCU/A/OFF switch to A.
j.
k. Take voltage reading on encoder calibrator. Divide voltage reading by
two to obtain encoder alinement voltage.
NOTE
At pin 3 and pin 12, voltage should be 12 V dc.
The encoder wheel must be turning to aline.
Turn B/ACCU/A/OFF switch to OFF.
1.
m.
Disconnect positive lead from pin 3 and attach to pin 1. Leave negative
lead on pin 12.
n.
Turn B/ACCU/A/OFF switch to A.
