6-7. TEMPERATURE PROBE (80T-150)
6-8. lntroduction
6-9. The 80T-150 Temperature Probe converts the
thermometer. It is ideally suited for surface, ambient and
liquid measurement, and lends itself easily to a wide
range of design, troubleshooting a n d 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.

6-11. CURRENT TRANSFORMER (801-600)
6-12. lntroduction
6-13. The Model 801-600 extends the maximum 2A ac
current measuring capability of the 8020A up to
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.

6-16. lntroduction
6-17. 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 M a ) minimizes
circuit loading, and thereby contributes to measurement
accuracy.

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.
