Introduction
6-52.
The Model 81RF
High Frequency
Probe, Figure
6-13,
extends
the frequency range of
the
8600
A
to include
100
kHz
to 100
MHz
for ac voltage
measurements from
0.25 to
30V
rms.
The
8
1
RF
operates
in conjunction with
the dc
voltage range, and
is
connected
to the
8600A
using
a shielded dual-banana plug and an
adapter.

.
The Model 80T-150 Temperature
Probe
is
a
self-
contained temperature-to-voltage
converter.
It is
designed
to provide
a direct temperature
reading on
the display
of
any
high
impedance
voltmeter
(1MS2)
capable of
1
mV
resolution,
and
at least
300
mV
full-scale readout.
The
probe
can be configured
to provide
either
one of
two
temperature
displays:
-50
to
+150°C
or
-58
to
+300°F.
6-58. Operating
power
for the
probe
is
provided by an
internal
lithium battery. Typically, the
battery
will
provide
up
to
1
000
hours of continuous
operation
before, replace-
ment
is
necessary.
An
on/off
switch
is
provided
to conserve
the battery
when
not
in use.

.
The
Battery Pack
provides the 8600
A
with the
capability
of
operating
as a portable (battery-operated)
in-
strument.
Four
nickle
cadmium
(Ni-cad)
batteries allow,
typically 8
hours of
portable operation before recharging
is
necessary.
The
batteries are recharged
by
connecting
the
8600A
to the ac power
line. If desired, the
8600A
can be operated during the charging
process,
however,
the
charging time
will
be
increased.
d. Select the desired voltage range.
e.
Connect
the probe's
ground
lead to a
suitable
ground.
f.
Touch
the
probe
tip
to the
circuit
point to be
measured.
g.
Observe
the voltage reading displayed
in volts
rms
on
the
8600A
readout.

CAUTION!
Damage may
result
if
alkaline, zinc-carbon, or
mercury
batteries are
charged
in
the
8600A.
