Continuity Measurements
1. Set the Function/Range switch to
W
/
position.
2. Turn off power to the circuit under test. External voltage across the
components causes invalid readings.
3. To toggle between the
W
/continity/diode modes, press SELECT button.
4. Connect the test leads to the two points at which continuity is to be tested.
The buzzer will sound if the resistance is less than approximately 100
W
.
Frequency Measurements
1. Set the Function/Range switch to the Hz position, and then press Hz-% to
toggle between "Hz" and "DUTY" mode.
2. Connect the red test lead to the "V
W
" jack and the black test lead to the
"COM" jack.
3. Connect the test leads to the point of measurement and read the frequency
from the display.
Duty Cycle Measurements
1. Set the Function/Range switch to the Hz position, and then press Hz-% to
toggle between "Hz" and "DUTY" mode.
2. Connect the red test lead to the "V
W
" jack and the black test lead to the
"COM" jack.
3. Connect the test leads to the point of measurement. The display will indicate
0.1% to 99.9% of the frequency duty cycle.
