Main Screen / Front Panel Details

Test Status Indicator Bar

The test status indicator bar includes three sets of test
indicators to aid during testing. On the left side are the user
selected

Range, Low Pass Filter

and

High Pass Filter

settings.

On the right side are indicator lights: a

uto-range

shows if the

auto-range feature is enabled and

auto-ranging

lights when

the device is actively auto-ranging. The

Voltage

and

PD Meter

O/R

light when the meter reading is beyond the scale of the

meters. The light in the middle is the pass/fail indicator for PD
levels that are over the user defined limit and shows in red
during a “failed” test.

Function Menu Bar

The six buttons along side (the function menu bar) are used to
enter the parameters and select settings for the unit and the
test. The function menu bar along with the up/down buttons
supply the user with control and the ability to set/alter the
test setup.

Main Screen

The test results are displayed on the main screen and two
graphical modes are available to view the test results: meter
mode and scope mode. The threshold shown graphically (in
color) together with different meter modes makes monitoring
of the test results simple.

When operating in the

meter mode,

you have opted to only

view the magnitudes of the partial discharge. In meter mode,
two meters are displayed: one for partial discharge and one
for voltage. You can select two different types of meters: a
traditional analogue meter display or a bar-type digital
display. In either mode you select the update rate as either
fast or slow.

The

scope mode

display looks just like an oscilloscope. You

select the type of oscilloscope display as an ellipse, straight
line or a sine wave. Gating features are also available in scope
mode.

Scope mode gives
you the ability to
see more than just
the magnitude of
the PD and allows
a

knowledgeable

user to perform
diagnosis of the
source of the PD.
You

can

also

choose

whether

there’s a single or
double gate, the
start point, and
the width to gate
out

undesirable

interferences.
