Introduction

1.
The Model 801-600
extends the maximum
2A ac current measuring
capability
of
the
instrument
up to
a
maximum of
600 amps. A clamp-on transformer
designed into the
probe
allows measurements to
be made without breaking the circuit
under test.
In use, the
current
carrying
conductor being measured serves
as the transformer’s primary,
while the
801-600
serves as the secondary. Because
of a high efficiency, quadrature
type of winding,
wire
size and location
of the conductor within the transformer
jaws do not affect
accuracy
of the
current
measurement.

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
having a 1
0 megohm input impedance.
A molded plastic body
houses the divider
and
protects the
user from the voltage being
measured.

Introduction
6-19.
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
resistors
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 Mil) minimizes circuit
loading, and
thereby contributes
to
measurement
accuracy.
