1. Wide, easily read 4-1/2 inch AC kilovoltmeter with 2% of
full scale accuracy.
2. Detachable 5 foot return (ground) lead. This lead is
always used in performing tests and is grounded for safety.
3. Detachable 5 foot high voltage lead with flexible
silicone rubber insulation for easy handling and user safety.
Control panel jacks are well recessed for safety.
4. Lighted rocker switch on the control panel which
indicates "power on" and that the High Voltage circuit is
energized.
5. Lighted leakage indicator. If excessive current is drawn
during the Hipot test, the yellow leakage indicator will
illuminate and an audio alarm will sound. To reset the unit,
simply decrease the output voltage to zero, place the power
switch into the H0ff" position and remove whatever is
causing the failure from the output leads.
6. The breakdown indicator is responsive to a broad band of
RF frequencies such as those generated when breakdown or
arcing across insulation takes place. Since this light is
only sensitive to RF currents, it will not normally indicate
when the equipment under test is short circuited or when
high leakage currents are present, but will indicate any
time there is actual sparking, arcing or corona. On the
other hand, since arcing is normally associated with
relatively high currents, the leakage light will usually
indicate simultaneously with the breakdown light. If the
output voltage of the HYPOT® JUNIOR is raised to a high
value and then the connection is made to the equipment under
test, the breakdown light will sometimes flicker. This does
not necessarily indicate an actual breakdown, but usually is
due to the fact that as the hot lead is brought to the
equipment, there is a point reached where the air gap
separating the test lead from the equipment is decreased
sufficiently to permit current flow by arcing through the
air. Once physical contact is established, the arcing ceases
(assuming no breakdown of the equipment). This arcing is
therefore normal to the establishing of the circuit, and
does not in itself indicate any breakdown in insulation.
7. Voltage adjust knob. This control varies the high voltage
from near zero to the full AC voltage. The voltage can be
adjusted only when the high voltage circuit is energized. It
is recommended that the voltage control be returned to zero
at the end of each test.
WARNING: Since the high voltage circuit of all these models
is energized whenever the unit is turned on, it is possible
that as much as the full output voltage will be present at
the output terminals if the voltage control is not at its
extreme counter-clockwise position.
8. Detachable 7-1/2 foot power cord with standard connector.
9. Line fuse accessible from the rear. ’’Shock safe" fuseholder.
10. Current Trip (sensitivity) adjustments accessible
through the back panel. The current at which the failure
alarm will trip is adjustable from approximately .3mA to 5mA
AC. Turn the controls counter-clockwise to decrease the
current setting and increase sensitivity. Turn it clockwise
to increase the current setting and decrease the sensitivity.

SCHEMATIC
This manual discusses the reasons why dielectric withstand
tests are required, the precautions necessary to ensure that
tests are done safely, and how such tests are accomplished
on various classes of materials, components and products.
In later chapters, the features of Associated Research 40OAI
series Hypots® Jr. are explained, along with a step by step
guide to its proper use. Finally, technical data on all
models is presented.
