Getting Started Manual
In addition to the function softkeys, the Analyzer test
functions may require using the navigation buttons to
select parameters as well. In the example above, the
leakage selection has
next to it. This icon indicates the
selection is controlled by pressing
or
. In this
example, the leakage current measurement is switched
between AC+DC, AC only, or DC only. The applied parts
indicator has
on the left end and
on the right end.
These icons indicate the use of
and
to select an
applied part.
The three buttons along the right side of the display
(
) control the wiring of the Analyzer’s
test receptacle for some electrical tests. The present state
of these three buttons is displayed along the right edge of
the display whenever these controls are active.
Prior to conducting any leakage tests with the Analyzer, it
is best to test the integrity of the ground connection
between the Analyzer’s test receptacle ground and the
DUT’s protected earth ground or enclosure. To test the
DUT ground using the 2-wire method with 200 mA test
current:
1. Ensure the power cord from the DUT is plugged into
the Analyzer’s test receptacle.
2. Press
to reveal the resistance function menu.
3. Connect one end of the test lead to the 2-WIRE
V/
Ω
/A jack.
4. Connect the other end of the test lead to the nulling
jack in the middle of the top panel of the Analyzer.
Note
Use the supplied null post adapter when you null
the test lead with the alligator clip.
5. Press the softkey labeled
Zero Leads
.
6. Move the test lead from the nulling post to the DUT’s
enclosure or protective earth connection. The
resistance is displayed as shown in Figure 6.
