2 Making Measurements
Keep the following in mind when measuring resistance.
NOTE
– The test leads can add 0.1 Ω to 0.2 Ω of error to resistance measurements. To test the
leads, touch the probe tips together and read the resistance of the leads. To remove
lead resistance from the measurement, hold the test lead tips together on a flat surface
or a null value circuit and press
subtracted from all future display readings.
Measuring conductance
Small conductance values correspond to extremely high resistance values. The nS range
allows you to easily calculate and determine the resistance of components up to 100 GΩ
(0.01 nS resolution).
To measure conductance, set up your multimeter to measure resistance as shown in
Figure 2-14. Press
Probe the test points, and read the display.
High-resistance readings are susceptible to electrical noise. Use averaging to smooth out
most of the noisy readings.

. Now the resistance at the probe tips will be
until the conductance measurement is selected (nS unit shown).
