c.
Select
the desired
current
range
in
accordance
with
Table 6-2.
d.
Clamp
probe
around
current
carrying
conductor
to

reading
in
amperes
on the
8600A
readout.
NOTE
Clamping
the probe
around
more
than
one
current
carrying
conductor
at a time
produces
a reading
that is
the vector
sum
of
the
currents
in the
conductors.

Introduction
6-25.
The
Model
80K-40
High
Voltage
Probe
as
shown
in
Figure
6-7, provides
the
1000X attenuation
necessary
to
extend
the
dc voltage
measuring
capabilities
of the
8600A
up to 40
kV
dc.
A
schematic
of the
80K40
probe
is shown
in Figure
6-8.

Operation
6-28.
Use
the
following
procedure
for
operating
the
8600A
with
the
80K-40
probe:
a.
Plug
the
80K-40
dual-banana
plug
into
the
V-S2
and LO
INPUT
terminals
on the
8600A.
b.
Depress
the DCV
pushbutton
(FUNCTION)
c.
Select the
desired
voltage
range
in
accordance with
Table
6-3.
d.
Connect the
common
probe
lead to
a suitable
ground
and
touch
the
probe
tip to
the circuit
point
to be
measured.
e.
Observe
dc voltage
reading
displayed
in kilovolts
on
the
8600A
readout.
CAUTION
Before
touching
probe
tip to
a
high
voltage
source,
always
connected
probe
common
lead
to circuit
common.
Removal
of the
probe
common
connec-
tion
during
a
measurement
may
result in
damage
to the
8600A.
