9 Measurement instruction
1. AC/DC voltage
1) Plug the red probe into “VΩ” socket, plug the black probe into “COM” socket.
2) Select AC/DC voltage measurement scale or intelligent range scale, connect the probe to the power source.
3) The screen displays the measurement result.
Attention:
• The voltage must not be higher than AC 600V. Voltage over 600V may damage the meter.
• Avoid electric shock when measuring high voltage.
• When voltage ≥30V, LCD display high-voltage symbol “
“
When voltage ≥600V, alarm goes off and the high-voltage symbol “ “ flashes.
2. Resistance
1) Plug the red probe into “VΩ” socket, plug the black probe into “COM” socket.
2) Select “Ω” measurement scale or intelligent range scale, connect the probe to the resistance terminals in parallel.
3) The screen displays the measurement result.
Attention:
• If resistance circuit is open or the resistance value is higher than the maximum range, LCD will display “OL”.
• Before measuring resistance, turn off all power sources of the measured circuit, and fully discharge the power of capacitor.
• If the resistance value is 0.5 on short circuit state,check if the probe connection is loose.
• Do not input AC/DC voltage over 30V for safety.
3.Continuity detection
1) Plug the red probe into “VΩ” socket, plug the black probe into “COM” socket.
2) Scan intelligent identification state can be set, if users want to switch to manual mode, select “
“ range scale and connect
the probe to the terminals of circuit load in parallel. If the resistance is < 300, the buzzer beeps continuously, which means
the circuit is conducting the resistance ≥500, the buzzer won’t beep.
Attention:
• Before measuring continuity, turn off all power sources of the measured circuit, and fully discharge the power of capacitor.
• Do not input AC/DC voltage over 30V for safety.
4. Diode
1) Plug the red probe into “VΩ” socket, plug the black probe into “COM” socket. The polarity of red probe is ”+”, the polarity of
black probe is ”-”.
2) Select ” “ range scale, it displays direct PN junction voltage. For silicone PN junction,the normal value is about 500mV to
800mV.
3) The screen displays the measurement result.
Attention:
• If diode circuit is open or the probe is connected inversely, LCD will display “OL”.
• Before measuring diode, turn off all power sources of the measured circuit, and fully discharge the power of capacitor.
• Do not input AC/DC voltage over 30V for safety.
5. Capacitance
1) Plug the red probe into “VΩ” socket, plug the black probe into “COM” socket.
2) Select ” “ scale and connect the probe to the capacitance terminals, read tested result from display screen.
