Using Conductance for High Resistance or
Leakage Tests
Conductance, the inverse of resistance, is the ability of a
circuit to pass current. High values of conductance
correspond to low values of resistance.
The Meter's 60 nS range measures conductance in
nanosiemens (1 nS = 0.000000001 Siemens). Because
such small amounts of conductance correspond to
extremely high resistance, the nS range lets you
determine the resistance of components up to 100,000
MΩ, 1/1 nS = 1,000 MΩ.
To measure conductance, set up the Meter as shown for
measuring resistance (Figure 5); then press C until
the nS indicator appears on the display.
The following are some tips for measuring conductance:
• High-resistance readings are susceptible to
electrical noise. To smooth out most noisy readings,
enter the MIN MAX recording mode; then step to the
average (AVG) reading.
• There is normally a residual conductance reading
with the test leads open. To ensure accurate
readings, use the relative (REL) mode to subtract
the residual value.
