6.3 Main PCB (PCB1) Calibration Procedure
The Main PCB must be calibrated when replaced. To calibrate the PCB use the calibration fixture
GBC P/N 706111164, and follow the calibration procedure outlined below. Calibration must be
performed with the new board installed in the machine.
1. The following tools are required to calibrate the Ultima 65.
A. Calibration Fixture (GBC P/N# 706111164)
B. Amp Meter (Amp Probe) (GBC P/N# 1999105)
C. Volt Ohm Meter with spring clips
D. Precision Screwdriver
E. Infrared Temperature Sensor (GBC P/N# 1722303)
2. Calibration must be performed when laminator is cold.
3. Unplug machine from 120V 60Hz outlet.
4. Remove left side cover (facing the front of unit).
5. Disconnect thermal sensor from Main PCB at the (- S/N +) and connect calibration fixture in
its place.
6. Set VOM to measure DC voltage.
7. Test points are on the two-pin connector (1+ / 1-) located at the top center area of the PCB,
identified as (GND). Locate test points on Main PCB and connect spring clips on leads from
VOM to test points.
8. Attach the Amp Probe to the infrared heater wires.
9. Plug the laminator into a suitable 120V 60Hz outlet.
10. Turn power switch to the (On) position.
11. Set control panel on (1.5 / 3 mil setting) with film on the unit and threaded.
12. Select SV1 on the Calibration Fixture. Adjust SV1 potentiometer on the Main PCB until you
read 1.15 VDC on the Multimeter.
13. Select SV2 on the Calibration Fixture. Adjust SV2 potentiometer on the Main PCB until you
read 3.45 VDC on the Multimeter.
NOTE: To properly calibrate the Main PCB, confirm the settings are correct by switching
between SV1 and SV2 on the calibration fixture and looking at the measured DC voltage on
the VOM. This procedure must be done quickly, because the Laminator is heating up and
your DC values will change.
14. Switch the Laminator to the (Off) position. Disconnect meter spring clips, and the Calibration
Fixture.
