9. The 80T
-
150 Temperature Probe converts the
8020A into a direct
-
reading (1 mV dc/O) OC or OF
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.

13. The Model 801-600 extends the maximum 2A ac
current measuring capability of the
8020A 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.

17. The Model 80K
-
40 extends the voltage measure
-
ment capability of the 8020A 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
Ma) minimizes
circuit loading, and thereby contributes to measurement
accuracy.

21. The 81RF Probe extends the frequency range of
the
8020A's voltage measurements capability to include
100 kHz to 100 MHz inputs from 0.25 to 30V rms. It
operates in conjunction with the
8020A dc voltage
ranges, and provides a dc output that is calibrated to be
equivalent to the rms value of a
sinewave input.
