WARNING
To avoid injury or damage to the meter, make sure to
turn off all power and discharge all capacitors before
measuring continuity.
4.9 Frequency/Duty Cycle
1. Insert the red test lead in the “INPUT” jack and the
black lead in the “COM” jack.
2. Move the rotary switch to the “Hz%” position. Connect
the test leads across the circuit to be measured.
3. Read measured resistance on the display.
4. Read measured duty cycle on the display.
