ESA620

Users Manual

During the self-test, the Analyzer checks its ac mains

input for proper polarity, ground integrity and voltage

level. The high voltage indicator illuminates briefly during

the self test. If the polarity is reversed, the Analyzer

indicates this condition and allows the polarity to be

reversed internally. If the ground is open, the Analyzer

displays this fault. If the mains voltage is too high or too

low, the Analyzer displays this fault and does not continue

until the supply voltage is corrected and the ESA620

power cycled off and then on again.

Accessing the Analyzer’s Functions

For each test and setup function, the Analyzer uses a

series of menus to access various Analyzer test and

setup variables. As shown in Figure 5, the Analyzer

indicates various leakage current tests along the bottom

of the display. An Exit selection is also indicated as a way

of backing out of the leakage current tests. Pressing a

softkey (F1 through F5) under a specific test will cause

the analyzer to setup for or perform the selected test.

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.

Setting Up the Analyzer

There are a number of Analyzer parameters that are

adjusted through a setup function. To access the Setup

menu shown in Figure 6, press .
