Continuity Test (See Figure 5)
1. Set the Function Switch to �.
2. Connect the test leads: Red to Temp VΩHz, 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 leads across the resistance.
6. Listen for the tone that indicates continuity (< 40 Ω).
When measuring continuity the meter emits a continuous tone when the resistance value
falls below 40
Ω .
Resistance Measurement (See Figure 6)
1. Set the Function Switch to Ω.
2. If RANGE is displayed, press the RANGE button to enable auto ranging.
3. Connect the test leads. Red to Temp VΩHz, Black to COM.
4. Turn off power to the circuit being measured. Never measure resistance across a
voltage source or on a powered circuit.
5. Discharge any capacitors that may influence the reading.
6. Connect the test leads across the resistance.
7. Read the display. If OL appears on the highest range, the resistance is too large to
be measured.
Note:
When measuring very low resistances, use Relative Measurement to eliminate the
test lead resistance (see Button Functions later in this manual).
