DANGER The LED may not be displayed due to installation condition of electrical circuit or equipment. Never touch the circuit under test to avoid possible danger even if the LED for NCVD is not displayed.

Check the functionality of LED on a well- known power supply prior to measurement. When the LED doesn’t light up, do not make measurement.

NCVD indication is affected by external volt- age, and how the meter is held or placed.

When the meter is on in any function, the non-contact volt- age detector will indicate with a

Resistance/Continuity/Capacitance Measurements

DANGER To reduce the risk of electric shock for Resistance, Continuity, and Capacitance measurements, never use the meter on an energized circuit. Make sure a capacitor is fully discharged before touching or attempting to make a measurement.

3. Discharge capacitor.

4. Connect the test leads to the

both ends of the capacitor

under test.

5. The reading is displayed.

CAUTION When the Rotary Dial is set to , OL should be displayed. If anything else is displayed, something may be wrong with the meter. Stop using the meter immediately.

Red LED on the display when an electric field exceeding 90V is detected. Place the edge of the jaw labeled “Voltage Detector” near the electric field.
