CONTINUITY TEST
1. Connect red lead to “-II-°C°F VΩHzhFE” and black lead to “COM”.
2. Set the range switch to “Ω ”, three functions are available by
pressing “Select”. For continuity testing, press “Select” until “ ” is
displayed on the screen.
3. Ensure all capacitors within the circuitry are discharged then connect
the test leads across the load to be measured.
4. If the circuit resistance measured is lower than 20Ω, the built-in
buzzer will sound. For resistance 600Ω or over, “OL” will be displayed
indicates measurement is out of range.
DIODE MEASUREMENT
1. Connect red lead to “-II-°C°F VΩHzhFE” and black lead to “COM”.
2. Set the range switch to “Ω ”, three functions are available by
pressing “Select”. For diode measurement, press “Select” until “ ” is
displayed on the screen.
3. Connect the red test lead to the anode of the diode to be measured
and black test lead to cathode.
4. The meter will show the approximate forward voltage of the diode.
If the connections are reversed, “OL” will be shown on the display.
CAPACITY MEASUREMENT
1. Connect red lead to “-II-°C°F VΩHzhFE” and black lead to “COM”.
2. Set the Range switch to “-II-”. Capacitance can be either measured
using probe or adaptor supplied. (NOTE: The polarity of the RED lead is
positive “+”)
3. Connect test probe across the capacitor and be sure the polarity of the
connection is observed. Alternatively insert capacitor into the connected
adaptor.
Please Note:
To avoid damage to the meter, disconnect circuit power and discharge all
high-voltage capacitors before measuring capacitance. The tested capacitor
should be discharged before the testing procedure. Never apply voltage to
the input, or serious damage may result.
