6-18. Introduction
6-19.
The
80T-150
Temperature
Probe
converts
the
instrument
into
a
direct-reading
(1
mV
dc/°)°C
or
°F
thermometer.
It
is
ideally
suited
for
surface,
ambient
and
liquid
measurement,
and
lends
itself
easily
to
a
wide
range
of
design,
troubleshooting,
and
evaluation
applications.
A
rugged,
fast-responding
probe-tip
with
a
350V
dc
standoff
makes
the
80T-150
one
of
the
most
versatile
and
easy-to-use
temperature
probes
available.

HIGH

PROBE
(80K-6)
6-22. Introduction
6-23.
The
80K-6
is
a
high
voltage
probe
designed
to
extend
the
voltage
measuring
capability
of
an
ac
dc
voltmeter
to
6000
volts.
A
1000:1
voltage
divider
provides
the
probe
with
a
high
input
impedance.
The
divider
also
provides
high
accuracy
when
used
with
a
voltmeter
havinga
10
megohm
input
impedance.
A
molded
plastic
body
houses
the
divider
and
protects
the
user
from
the
voltage
being
measured.

HIGH

PROBE
(80K-40)
- 6-26. Introduction
6-27.
The
Model
80K-40
extends
the
voltage
measurement
capability
of
the
instrument
up
to
40
kV.
Internally,
the
probe
contains
a
special
1000:1
resistive
divider.
Metal-film
resistor
with
matched
temperature
coefficients
comprise
the
divider
and
provide
the
probe
with
its
excellent
accuracy
and
stability
characteristics.
Also,
an
unusually
high
input
impedance
(1000
MQ)
minimizes
circuit
loading,
and
thereby
contributes
to
measurement
accuracy.
