4.4 Operating Instructions
The operation of the Test Filter Pack (32863) is similar to the operation of the Wide Range Filter Pack
(37617) described in Section 2. Prior to taking measurements, it is suggested that the battery and
internal calibration be checked as described in Sections 2.1 and 2.2. Position the kVp Divider as
described in Section 2.5, Geometry of Setup.
Set up the oscilloscope to read the 3.0 volts expected from the Model 35080B kVp divider using the Test
Filter Pack (32863), and make an exposure. On a properly functioning unit, the observed waveform
amplitude will be 3.00 Volts ± 1%. Be aware that the oscilloscope accuracy may not be adequate for this
test. The calibration of the kVp Divider can only be verified to within the accuracy of the oscilloscope or
other readout device used. If the unit appears to be out of calibration, refer to Section 10.4, Calibration.
