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.
