8. Continuity test
(figure 9)
Before testing continuity, power off and no charge in capacitor to avoid
damages to the Meter. Measuring value inputs from “V Ω mA” jack (red test
lead) and “COM” jack (black
test lead). If the impedance
of measured circuits is equal
or less than 80
Ω , the Meter
would clatter, it means the
circuit is close. Display on
LCD is circuit resistance.
(80
Ω is a dividing value for
OPEN or CLOSE.)
