4.16 CONTINUITY TESTING
WARNING
When testing the circuit continuity, be sure
that the power of the circuit has been shut
down and all capacitors have been
discharged fully.
4.16.1 Connect the black test lead to the COM jack
and the red test lead to the
jack.
4.16.2 Set the transform switch at the
range position.
4.16.3 put down the "FUNC." transformed at
continuity test.
4.16.4 Connect test leads across two points of the
circuit under testing.
4.16.5 If continuity exists
（i.e., resistance less than
about 40
）, built-in buzzer will sound.
4.16.6 You can get reading from LCD.
NOTE:
If the input open circuit (or the circuit resistance
measured is higher than 400
), then the figure
‘0L’ will be displayed.
4.17 FREQUENCY MEASURING
4.17.1 Connect the black test lead to the COM jack
