Using Conductance for High Resistance 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 unit of conductance is the Siemens (S). The meter’s 50 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 is used to measure the resistance of components up to
100,000 M , or 100,000,000,000
To measure conductance, position the rotary switch to
set up the Meter as shown in Figure 18. Move the menu selector
to the menu item labeled Ohms,nS,j and press the softkey
labeled nS.
There is normally a residual conductance reading with the test
leads open. To ensure accurate readings, press the softkey
labeled Menu. Move the menu selector to the menu item labeled
REL and press the softkey labeled REL to subtract the residual
value with the test leads open.

R is disabled when the Meter is measuring
conductance.
