5. The buzzer does not sound if the resistance of a circuit under test is°100Ω, it indicates a possible broken circuit.
6. Read the resistance value on the display.
Note
• Open circuit voltage is around 3V.
4.7 DIODE TESTING
Use the diode test to check diodes, transistors, and other semiconductor devices. The diode test sends a current through the semiconductor
junction, and then measures the voltage drop across the junction. A good silicon junction drops between 0.5V and 0.8V.
To test out a diode while removed from a circuit, connect the Meter as below:
1. Insert the black (negative) test lead into the COM input terminal.
2. Insert the red (positive) test lead into the VΩ input terminal.
3. Set the function switch to diode position " "
4. For forward voltage drop readings on any semiconductor component, place the red test lead on the component's anode and place the black
test lead on the component's cathode.
5. Read the nearest value of the diode's forward voltage drop as displayed.
Notes
• In a circuit, a good diode should still produce a forward voltage drop reading of 0.5V to 0.8V; however; the reverse voltage drop
reading can vary depending on the resistance of other pathways between the probe tips.
• Connect the test leads to the proper terminals as in figure above to avoid error display. The LCD displays OL indicating open-circuit
for improper connection.
• Open circuit voltage is approximately 3V.
5.0 HOUSEHOLD BATTERY TESTING
There are two ranges for measuring common household batteries, 1.5 V and 9 V.
1. Insert the black (negative) test lead into the COM input terminal.
2. Insert the red (positive) test lead into the terminal.
3. Set the function/range switch to the appropriate battery position.
4. Touch the test leads to the positive and negative terminals on the battery. With DC voltage, the polarity of the test leads is a factor. Touch the
black (common) test lead to the negative (-) terminal and the red test lead to the positive (+) terminal.
5. Read the value of the measurement displayed. If the leads are reversed a "-" indicator will appear on the display.
6.0 BATTERY REPLACEMENT
To avoid false readings, which could lead to possible electric shock or personal injury, replace the battery as soon as the battery
indicator appears
1. Disconnect the connection between the test leads and the circuit under test, and remove the test leads from the input terminals of the meter.
2. Turn the Meter power off.
3. Remove the screw from battery door, and separate the battery door from the case bottom.
