Figure 3-7. Conductance Measurement

The following are some tips for measuring conductance:

High-resistance readings are susceptible to electrical
noise. Use averaging to smooth out most noisy
readings; press

M

until AVG appears in the

display.

There is normally a residual conductance reading with
the test leads open. To ensure accurate readings,
press

D

with the test leads open to subtract the

residual value.
