Look for cracks or missing plastic. Carefully
look at the insulation around the terminals.
• The measurement must be made within the
allowable measuring range.
• Do not use the product around explosive gas,
vapor, or in damp or wet environments.
• When the voltage to be measured exceeds
36V DC or 25V AC, the operator shall be
careful enough to avoid electric shock.
• Misuse of mode or range can lead to hazards,
be cautious. “OL” will be shown on the display
when the input is out of range.
• Low level of a battery will result in incorrect

Measurements
Measure DC/AC Voltage (＞0.8V)
1. Only when the voltage is higher than 0.8V, this
product will show the display.
2. Put the red lead into the terminal, put
the black lead to the COM terminal.
3. The DC or AC voltage will be auto matched.
4. Touch the probes to the correct test points of
the circuit to measure the voltage.
5. Read the measured voltage on the display.
Measure Resistance
1. Put the red lead into the terminal, put
the black lead to the COM terminal.
2. The resistance measure will be auto matched.
3. Touch the probes to the desired test points of
the circuit to measure the resistance.
4. Read the measured resistance on the display.
Test for Continuity
1. Put the red lead into the terminal, put
the black lead to the COM terminal
2. The continuity measure will be auto matched.
3. Touch the probes to the desired test points of
the circuit.
4. The built-in beeper will beep when the
resistance is lower than 50Ω, which indicates a
short circuit while the central LED light will light .
