Active Heads

A range of Active Heads are available for the 9500B Oscilloscope calibrator. Active head
connector wear can seriously impact product specifications. Fluke Calibration
recommends that connectors are inspected for wear or damage before use. The
recommended interval for connector replacement based on average use is every two
years, and once per year for Active heads with higher than average use.
Contact a Fluke Calibration authorized service center for replacement. Attempts to
change connectors without the correct tools, training or calibration system is not
recommended.

Model 9500B Test and Selftest

Types of Tests

There are four main types of selftest, 'Base', 'Heads', 'All' and 'Fast'. The Fast selftest is
also performed automatically at power-on. In addition, the interface for front panel
operation can be selectively tested, covering such areas as display memory integrity,
keyboard operation, the display itself, integrity and formatting of static RAM memory
cards for Procedure mode, the correct operation of a connected tracker-ball, and the
correct operation of a connected printer. These tests are detailed in the following
paragraphs.
Please Note that all Heads should be disconnected from the UUT Oscilloscope before
initiating a Self Test. Failure to disconnect may result in failed tests.

Test Mode

Test mode is selected from the Mode Selection menu, which is displayed by pressing the
