Verification procedures
The verification procedures are explained in detail in the following paragraphs. Refer to the
Recommended test equipment
table and the respective diagrams for test equipment and
connections. Note that each procedure is performed both with the output filter off and with Filter 1
enabled. Since the Model 2290-5 specifications are the same for both Filter 1 and Filter 2, only the
Filter 1 configuration requires testing.
The following procedures use high voltage. Use extreme care to avoid electrical shock that
could result in personal injury or death. Do not touch any exposed circuitry while the high
voltage is enabled.
High voltage cables can store a charge even when disconnected from the unit. Always turn
off the high voltage and make sure all cables and circuitry are completely discharged before
connecting or disconnecting cables or other circuitry.
