Figure 2-9 describes how to select the high input impedance dc voltage
function (the ac voltage function does not operate in this mode). Notice that
all of the function switches must be out to select this function. Either the 2V
or the 200 mV range may be selected. Refer to Chapter 3 for more
applications of this function, including a technique for using the 8060A as an
electrometer to measure extremely low currents.
Note
When taking measurements in the high impedance dc voltage
function, do not select any ranges except the 2V or 200 mV ranges.
Measurement in other ranges will result in erroneous readings.
Note
When the high impedance dc voltage function is selected and no
input is applied, noise from the environment (such as rf or power
line noise) may cause the 8060A to display OL (overrange).

1. Select the 2V or
the 200 mV range.
2. Ensure all function
switches are out.
3. Connect the test leads as shown.
4. Heed the input overload limits
(Table 2-2) and connect the leads to
the circuit being measured.
5. Read the measured value on the display.
