Electrical tester

Frequency and Duty Cycle

In Current Mode (A)
WARNING:
REMOVE THE TEST LEADS FROM THE METER
WHEN PERFORMING A CURRENT MEASUREMENT
WITH THE FORK TO AVOID ELECTRICAL SHOCK
AND INJURY.
1.Turn the rotary switch to the current position.
2.Insert the conductor to be measured inside the fork.
3.Press "Hz/%" button to measure frequency.
4.Press "Hz/%" again to measure duty if necessary.
5.Read the measured frequency or duty cycle value on
the display.
Note:
• Measuring two or more conductors will cancel out
readings. Only measure one conductor at a time.
• " "indicates the maximum input current is 200A AC RMS.
• Frequency range is 10Hz~1kHz. When the frequency
being measured is less than 10Hz or if the frequency is
higher than 1kHz, the accuracy is not guaranteed.
In Voltage Mode (V)
WARNING:
DO NOT MEASURE VOLTAGES OF MORE THAN
600V AC TO AVOID ELECTRICAL SHOCK AND
INJURY.

1.Insert the black test lead into "COM" jack and red test
lead into "INPUT" jack.
2.Turn the rotary switch to the
to switch to AC voltage.
3.Press "Hz/%" button to measure frequency.
4.Press "Hz/%" again to measure duty if necessary.
5.Connect the test leads across the voltage source or load.
6.Read the measured frequency or duty cycle value on
the display.
Note:
• " "indicates the maximum input current is 600A AC RMS.
• Frequency range is 10Hz~10kHz. When the frequency
being measured is less than 10Hz or if the frequency is
higher than 10kHz, the accuracy is not guaranteed.
In Hertz Mode (Hz)
WARNING:
DO NOT MEASURE INPUTS OF MORE THAN 250V
AC TO AVOID ELECTRICAL SHOCK AND INJURY.
1.Insert the black test lead into "COM" jack and red test
lead into "INPUT" jack.
2.Turn the rotary switch to the Hz position. The default
mode is frequency; press "Hz%" to switch to duty cycle
if necessary.
3.Connect the test leads across the voltage source or load.
4.Read the measured frequency or duty cycle value on
