2.2.1 Establishing the Connections
CAUTION
Using a low frequency to measure capacitors with a particular polarity (for
example, electrolytic capacitors) results in a reverse bias being applied.
In some cases this could damage or destroy the capacitor, and therefore
a DC bias should always be applied while making the measurements.
Also be sure that the positive terminal of the capacitor is connected to
the Hcur terminal on this unit.
When measuring capacitors with a particular polarity (for example,
electrolytic capacitors), always apply a DC bias.
If the DC bias is not applied, a reverse bias may be applied, damaging or
destroying the capacitor.

2.2 Connecting the Test Leads
The 3532-50 has five test terminals: H
CUR
terminal (to which the test signal
is supplied); H
POT
terminal (detected voltage high terminal); L
POT
terminal
(detected voltage low terminal); L
CUR
terminal (test current detected
terminal), and GUARD terminal (connected to the chassis of the unit).
If using a test lead set supplied by
HIOKI
, connect the red leads to the H
CUR
terminal and to the H
POT
terminal, and connect the black leads to the L
CUR
terminal and to the L
POT
terminal.
The unit is designed and adjusted for 75
Ω
coaxial cable test leads. It is
best to use
HIOKI
test leads.
