6-6. High Voltage Probe (80K-40)
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 M
Ω
)
minimizes circuit loading, and thereby contributes to measurement accuracy.

6-7. High Frequency Probe (83RF)
The 83RF Probe extends the frequency range of your multimeter’s voltage
measurement capability to include 100 kHz to 100 MHz inputs from 0.25 to
30V rms. The probe operates in conjunction with the instrument’s dc voltage
ranges, and provides a dc output that is calibrated to be equivalent to the rms
value of a sinewave input.
