2-20. Conductance (S)
Selection of the conductance function is described in Figure 2-14. The range
is 2000 nS (nS = nanosiemens or 10
-9
siemens, 1 siemen = 1/
Ω
) which
corresponds to a resistance range from 500 k
Ω
to 10,000 M
Ω
.
Conductance is a good way to measure high resistances, such as leakages in
diodes, capacitors, pcbs, or insulators. For example, you can measure the
conductance of a pcb and then covert the measurement to resistance by
referring to Figure 2-15. If you are measuring the leakage of a capacitor, be
sure to discharge it first by shorting its leads together. The positive (+) lead
of polarized capacitors should be connected to the V
Ω
S input.

1. Push both switches
simultaneously to set range.
2. Press switch in for
conductance function.
3. Ensure all other switches are out
(except the AC/DC switch which can
be in or out).
4. Connect the test leads as shown above.
5. Ensure that the device being measured
contains no electrical energy.
6. Heed the input overload limits (Table 2-2) and connect
the test leads to the device being measured (connect the
test lead from the V S input to the + lead of polarized
capacitors for leakage measurements).
7. Read the measured value on the display.
