High Voltage
Settings
Frequency
Available only when
“Hipot Mode: AC” is selected.
Selections
25, 30, 50, 60 Hz.
“Frequency” defines the frequency of AC waveform cycle when AC is selected
for the
“
Hipot
Mode
” setting
.
This setting is often dictated by a customer or engineering specification.
DWV Voltage
Available only when
“Hipot Test: Advanced”
is selected.
DC Selections
1000V Unit:
50V, 100V, 200V, 300V, 400V,
500V, 630V, 800V, 900V, 1000V
1500V Unit:
50V, 100V, 200V,
300V, 400V, 500V, 630V, 800V,
900V, 1000V,
1100V, 1200V,
1300V, 1400V, 1500V
“DWV Voltage” determines the voltage that is applied to each net in the Dielectric Withstand
Test
where gross hipot failures, such as arcs and breakdown conditions, are detected. This
setting is often dictated by a customer or engineering specification. If you do not have a
specification, the
High Voltage guidelines for the settings (page 50) are applicable to this setting.
DWV Max Current
Available only when
Hipot Test: Advanced
is selected.
Selections
100uA (.1mA), 200uA (0.2mA),
500uA (0.5mA), 1mA, and
1.5mA
“DWV Max Current” determines the maximum current that is allowed to flow out of each net
during the Dielectric Withstand Test. If current flow exceeds this setting, the tester will fail the
tested assembly and display a dielectric error, indicating an arc or insulation breakdown.
DWV Max Current Guidelines
The DWV Current setting is often dictated by a customer or engineering specification. If you
don’t have a specification, here are some general guidelines:
Use a lower setting to provide a more stringent test, but too low of a setting may cause
false failures.
Cables with higher internal capacitance may necessitate using a higher setting,
especially if you are testing with a VAC where current surges occur throughout the test
period proportionally to the capacitance in the tested device.
