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 “VΩ mA” jack (red test

lead) and “COM” jack (black

test lead). If the impedance

of measured circuits is equal

or less than 80Ω, 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.)
