Continuity Test
The tester can measure resistance and alert the user if the resistance value is less than
200kΩ.
1. Before taking a continuity test, make sure that power to the device or circuit under test
is off and that all capacitors are discharged.
2. Touch the test tips to the device under test.
3. If the resistance is less than 200kΩ, the tester will sound an audible alert; the LCD will
display “000”, and the
continuity LED will light.
Flashlight
Press and hold the button to turn the flashlight on. Release the button to turn the flashlight off. After the
button is released, the light will turn off after 12 seconds (approx).
Maintenance
Battery replacement
1. The
BAT
icon will appear in the lower right of the display
when the battery voltage becomes low. Replace the batteries
when this appears.
2. Disconnect the meter from any test device or circuit before
opening the tester.
3. Loosen the recessed Phillips head screw at the bottom of the
tester. Do not remove the screw.
4. Hold the meter and pull the lower portion of the meter off until
the batteries are exposed.
5. Replace the two ‘AAA’ batteries observing polarity and
dispose of the old batteries properly.
6. Slide the meter back together and replace the screw.
Cleaning and Storage
Before cleaning the tester, ensure that the test leads are not connected to any circuit or
device. Wipe the meter only with a damp cloth as needed. Do not apply abrasives, solvents,
or other cleaners to the surface of the meter. Store with the battery removed and avoid
extreme temperature and humidity.
