Connect the test leads to the jacks marked “VΩ” and “COM”. Set the selector to the buzzer symbol.
If the meter is used to measure conduction, the built-in buzzer will sound whenever the measured
resistance drops below 30 Ω. The buzzer can also be heard in the range from 30 Ω to 100 Ω.
It is
absolutely forbidden to test conductivity in circuits through which electric current is fl owing.
MAINTENANCE AND STORAGE
Wipe the meter with a soft cloth. Larger amounts of dirt should be removed with a slightly damp
cloth. Do not immerse the product in water or any other liquid. Do not use solvents, corrosive or
abrasive agents for cleaning. Care should be taken to keep the contacts of the meter and the test
leads clean. Clean the contacts of the test leads with a cloth slightly soaked in isopropyl alcohol. In
order to clean the contacts of the meter, turn off the meter and remove the battery. Turn the meter
over and shake it gently so that larger pieces of dirt fall out of the meter connectors. Lightly soak a
cotton stick with isopropyl alcohol and clean each contact. Wait until the alcohol evaporates, then
install the battery. The meter should be stored in a dry room in the supplied unit packaging.
