SINGLE TEST PEN TESTING
•
For single test pen testing, hold L2 and connect L2 to an unknown conductor.
•
If the voltage of the conductor under test is higher than 100V AC, the LED (72-
3570/72-3575) or high-voltage symbol will illuminate and the meter will buzz.
•
To determine if a conductor is live, with a single pen, contact the L2 probe tip with
the conductor under test.
•
If the AC light (72-3570/72-3575) illuminates, or the "
displayed on the LCD, it means that the wire measured is a live wire.
•
To determine if the socket is electrified, insert L2 into the terminal. If the AC light
or "
" symbol is displayed along with continuous beeping, it means the socket is
live.
Notes:
•
Single test pen testing can only determine whether or not a conductor is live. It
cannot indicate the voltage level.
•
In the presence of adverse environmental factors such as temperature, humidity,
magnetic field, static electricity and others, the single test pen will show an
unstable reading.
•
When the measured conductor is >200VAC, the buzzer will remain silent, while the
AC LED will illuminate and a low voltage reading will be displayed.
•
The LCD may display a reading (72-3575/72-3580), but the voltage value should
not be considered as the actual measured value as it is simply indicating the
conductor is electrified.
DETECTION WITHOUT BATTERIES (72-3570/72-3575 only)
•
The tester may perform basic measurements with no battery power.
•
Connect the two test pens to the circuit under test. If the circuit has a voltage
≥50VAC/120VDC the high voltage LED will illuminate, indicating a dangerous
voltage.
•
The LED brightness will be proportional to the voltage measured.
CONTINUITY TEST
•
To confirm if the conductor to be measured has continuity, the meter can test for
this.
•
Connect the two test pens to both ends of the object to be measured; if the
resistance is 0~100kΩ, the continuity LED (72-3570/72-3575) will illuminate or
the continuity symbol (72-3580) will display on the LCD and the buzzer will sound
continuously.
•
If the resistance is >150kΩ, the continuity LED (72-3570/72-3575) will not
illuminate or the continuity symbol (72-3580) will not display and the buzzer will not
sound.
•
Prior to any test, be sure the object to be measured is not live.
