To set the GFCI current limit:
1. From the Setup menu, press the softkey labeled
Instrument to reveal the instrument setup selections.
2. Press the softkey labeled More to reveal additional
menu selections.
3. Press the softkey labeled GFCI Limit to open a scroll
box above the softkey label.
4. Press the Up or Down navigation arrow buttons to
adjust the current limit to the desired value.
5. Press the softkey labeled GFCI Limit to exit the GFCI
limit setup function.
Setting Polarity Switching Delay
When switching the polarity of the Analyzer’s test
receptacle, a delay can be set to control the actual switch
time. Use the Polarity Switching Delay to protect the
internal components of the Analyzer from transient
effects. Transient effects can occur when the DUT has a
highly capacitive or inductive power supply. These types
of power supplies are in larger DUTs, for example,
ultrasound, dialysis, and portable X-ray machines. If you
think the DUT has a highly capacitive or inductive power
supply, increase the Polarity Switching Delay from 1
second (default) to at least 5 seconds. This increase
allows the DUT to self-discharge safely.
To set the polarity delay:
1.
From the Setup menu, push

or

until the
Polarity Delay variable is highlighted.
2. Push the “Enter” button.
3. Push

or

to highlight one of the preset delay
values.
4. Push the “Enter” button..
Setting the Display Contrast
There are two methods for setting the display contrast.
From the Select a Test…. menu or through the setup
menu.
Whenever the Analyzer displays its start-up menu (Select
a test…), pressing

or

will increase or decrease the
display’s contrast respectively. Press the softkey labeled
Done to exit contrast setup.
Another way to adjust the contrast is through the
Analyzer’s setup menu.
1. From the setup menu, press the softkey labeled
More twice to set F1 to the display contrast function.
2. Press the softkey labeled Display Contrast .
3. Press

or

to increase or decrease the display’s
contrast respectively.
4. Press the softkey labeled Done to exit contrast
setup.
