Frequency and % Duty Cycle Measurements
Observe all safety
precautions when working on live voltages.
WARNING:
1. Set the rotary function switch to the
V HZ %
position.
2. Select AC voltage using the
button.
3. Press the
button once to display
Hz
(frequency). Pressing the button again
will toggle the display to % (duty cycle).
4. Touch the test probe tips to the circuit
under test.
5. Read the value on the LCD display.
Non-contact AC Voltage Detection
(Detection range 100 to 600V)
Risk of Electrocution. Before use, always test the Voltage
Detector on a known live circuit to verify proper operation.
WARNING:
1. Hold the detector probe tip close to an AC voltage.
2. If AC voltage within the specified range
is present, the indicator light will illuminate.
NOTE:
Insulation type and thickness, and
distance from the voltage source and other
factors may effect operation. Use other methods
to verify live voltage if there is any uncertainty.
NOTE:
The detector is designed with high
sensitivity. Static electricity or other sources
of energy may randomly trip the sensor.
This is normal operation.
