9. Run the Crosslinker in calibration mode by depressing the STOP/RESET button and
turning the power switch on at the same time. At this point, both pens should start
recording information on paper. Sometimes either pen will record zero information
regardless of the lights in the crosslinker being on, if this is the case, check for bad
connections.

10. During calibration, check the voltage levels on both pens. By adjusting the
potentiometers on the PBC, adjust the values for U4 and U5. Depending on the voltage
used, from past units it has been found that the optimum values for these levels are:
used, from past units it has been found that the optimum values for these levels are:
VOLTAGE RANGE FOR U4

115V 3.3-3.5V
2.1-2.3V
220V 3.5-3.7V
1.7-2.0V
100V 2.5-2.7V
2.6-2.9V
11. When the calibration cycle is finished, move both pens to UP and ZERO positions.
12. Unplug the UVX-25 sensor and disconnect the probe for PEN 2.
13. At this point, it is necessary to check the energy levels of the crosslinker to see if the unit
was calibrated properly. Slide the UVX-25's cable through the lower hole of the inner
chassis and plug it into the radiometer.
chassis and plug it into the radiometer.
14. Connect the radiometer to PEN 2 of the chart recorder.
15. Select 1V scale for PEN 2 and a speed of 60mm/min.
16. Lower both pens, turn the CHART DRIVE switch on, change the pens' switches to
15. Select 1V scale for PEN 2 and a speed of 60mm/min.
16. Lower both pens, turn the CHART DRIVE switch on, change the pens' switches to
MEASURE position and adjust for zero level.
17. Select an energy level of 600 Joules on the crosslinker and press the START button.
18. When the cycle is completed, repeat for 1,200 and 2,000 Joules levels.
19. Calculate the actual amount of energy and compare it with the energy selected. They
should be within a range of +/- 10%. If this is not the case, adjustments should be made
during a repeat calibration. Repeat all the above procedures until the actual levels are
within range.

within range.
20. When the three levels of energy are acceptable, disconnect the sensor and the chart
recorder from the Crosslinker. At this point, the unit is ready to be tested.
