6-1. Introduction
This chapter explains how to perform the routine user maintenance required to you’re
your Instrument in optimal operating condition. The topics covered in this chapter
include:
• Changing the User Password
• Running the Confidence Test
• Replacing the Fuse
• Cleaning the Air Filter and External Surfaces
Calibration is explained in Chapter 7.
6-2. Confidence Test
The Confidence Test provides an indication that instrument performance has not
deteriorated significantly. The test for connected Auxiliary units is run from the 6100B
Master instrument. The test is not designed to be used to determine service intervals as
the measurements made are relatively crude compared with those that would be made at
routine calibration and adjustment.
Note
Some temperature (Pic) tests may report percentage error of 100 % but this
is normal and should not be of concern.
6-3. Setting Up and Running the Confidence Test
Navigate to the Waveform Menu with . If necessary, push until the top-level
softkey menu is displayed. See Figure 6-1.
Select Support Functions, Diagnostic tools, and enter the user password. Push the
Run Self Tests softkey.
The softkeys associated with the Self Test pop up menu allow you to:
• Under the Select Test Channels softkey,
select which channels to test i.e., L1 Voltage,
L1 Current ... N Current
• Choose which channel sub-components to test, i.e., all boards, the DSP board, the
control board or the first or second slave boards
• Start the self test
• Save the test results to external media via USB ports
Once the test required regimen has been set up, push Start Self Test to initiate the test.
Note
Remember, when navigating the various menus, the key takes you up
through the softkey hierarchy.
When the test is complete a summary report is presented in the Self Test menu.
The Test Pathway menu allows more detailed diagnosis of test results but this is
essentially a tool provided for service centers. Although the Test Pathway facilities are
available, a detailed description is not provided here as the technical content is beyond
the scope of this manual.
