4.18.3 Adjustment Procedure
1. Input a PAL black level signal.
2. Connect DC power supply (100 V - 150 V) and electronic dummy load (150 mA) as shown
below.
3. Turn on the monitor.
4. Set the SCAN switch to over-scanning mode (original size).
5. Set the CONTRAST and BRIGHT controls to their minimums to allow the screen to become
black.
6. Check that the high voltage is 23.8 kV± 1.2 kV.
7. Change the input signal to a Philips pattern signal.
8. Adjust the CONTRAST and BRIGHT controls to obtain a digital voltmeter reading of 7.0 V±
0.05 V.
9. Turn on the electric dummy load and adjust it to obtain current of 150 mA.
10. Turn on the DC power supply, increase its output voltage gradually, and check that a shutdown
occurs at the high voltage of 27.0 kV± 1.5 kV and the digital voltmeter reading of 7.0 V±0.05
V.
Note:
11. A shutdown means that the high voltage vanishes and the raster stops.
