performance testing procedures.
THIS POWER SUPPLY GENERATES VOLTAGES
THAT ARE DANGEROUS AND MAY BE FATAL.
OBSERVE EXTREME CAUTION WHEN
WORKING WITH HIGH VOLTAGE.
6.1 Periodic Servicing
Approximately once a year (more often in high dust
environments), disconnect the power to the unit. Use
compressed air to blow dust out of the inside of the unit.
Avoid touching or handling the high voltage assembly.
6.2 Performance Test
HIGH VOLTAGE IS DANGEROUS.
ONLY QUALIFIED PERSONNEL SHOULD
PERFORM THESE TESTS .
High voltage test procedures are described in Bulletin
STP-783, Standard Test Procedures for High Voltage
Power Supplies. Copies can be obtained from the
Spellman Customer Service Department. Test equipment,
including an oscilloscope, a high impedance voltmeter,
and a high voltage divider such as the Spellman HVD-
100 is needed for performance tests. All test components
must be rated for operating voltage.
6.3 High Voltage Dividers
High voltage dividers for precise measurements of output
voltage with an accuracy up to 0.1% are available from
Spellman. The HVD-100 is used for voltages up to
100KV. The Spellman divider is designed for use with
differential voltmeters or high impedance digital
voltmeters. The high input impedance is ideal for
measuring high voltage low current sources, which would
be overloaded by traditional lower impedance dividers.
