Continuity Testing - See Figure 5
1. Set the Function Switch to Ω and press the SELECT button until  is displayed.
2. Connect the test leads: Red to +, Black to COM.
3. Turn off power to the circuit being measured.
4. Discharge any capacitors that may influence the reading.
5. Connect the test probes across the resistance or the two points of test.
6. Listen for the tone that indicates continuity (>10 Ω and < 120 Ω).
Testing Diodes - See Figure 6
1. Set the Function Switch to Ω and press the SELECT button until  is displayed.
2. Connect the test leads: Red to +, Black to COM.
3. Turn off power to the circuit being measured.
4. Free at least one end of the diode from the circuit.
5. Connect the test probes across the diode noting polarity.
6. Read the display. A good diode has a forward voltage drop of about 0.6 V. An open
or reverse biased diode will read .0L.
Measuring Capacitance - See Figure 7
1. Set the Function Switch to Ω and press the SELECT button until  is displayed.
2. Connect the test leads: Red to +, Black to COM.
3. Turn OFF power to the circuit being measured.
4. Discharge the capacitor using a 100 kΩ resistor.
5. Free at least one end of the capacitor from the circuit.
6. Connect the test probes across the capacitor.
7. Read the display.
8. Relative zero mode can be used to zero out the parasitic capacitance of the leads
and the internal protection circuitry of the meter when measuring low capacitance
in the order of Pico Farad (pF).
Measuring Temperature - See Figure 8
1. Set the Function Switch to °F / °C and press the SELECT button until correct tempera-
ture range is displayed.
2. Connect the thermocouple to the input jacks: + to +, - to COM.
You can also use a plug adapter TA-1A (optional purchase) with banana pins to type-K
socket to adapt other type-K standard mini plug temperature probes.
