fixture is capable of handling 25.0 kV (For model with 13 inch CRT)
or 30.0 kV (For model with 20 inch CRT) without causing X-
Radiation.
NOTE :
It is important to use an accurate periodically calibrated high
voltage meter.
1. Reduce the brightness to minimum.
2. Set the SERVICE switch to SERVICE .
3. Measure the High Voltage. The meter reading should indicate 23.5
kV±1.5 kV (For model with 13 inch CRT) or 28.5 kV±1.5 kV (For
model with 20 inch CRT).
If the meter indication is out of tolerance, immediate service and
correction is required to prevent the possibility of premature
component failure.
