3. Set the Short-circuit resistance.
The default value is set as 50Ω before leaving factory. The value can be
changed by using direction keys. You also can execute the Continuity
measurement directly without modification.

to turn on or off the Beeper. If the circuit is continuous, the
instrument will beep once when the Beeper is turned on.
5. Search for the test point and read measurement result.
NOTE:
Before testing continuity, please cut off the power and discharge all the
high-voltage containers to avoid damages to the Multimeter.
