Acoustic Continuity Test
The continuity test (range selector switch (1) set to position
is suitable for testing low-ohmic connections with a
resistance value of
≤
1.5
Ω
.
No external voltage must be applied during the measure-
ment!
The forward direction of semiconductor elements should
not be tested by the audible continuity test but only
according to the deflection method (see chapter 4.3).
When using the audible continuity test, inductive voltage
spikes appear at the meter connectors which could dam-
age the semiconductors.

End of Measurement
After the measurement, the range selector switch (1)
should be set to "0" to conserve the battery life.
