2. Connect the probes to the device to be measured.
3-3 Measuring DC Voltage (V)
1. Rotate the function selector to the V
'
position.
2. Connect the probes to the device to be measured.
3-4 Measuring Continuity and Resistance ( Ω )
1. Rotate the function selector to the
Ω□
position.
2. Verify that the power to the circuit under test is off. Connect test leads to the circuit to make the measurement.
3. The internal sounder will operate if the resistance of the circuit under test is less than 25
Ω , it will then turn off if
the resistance is increased beyond 400 Ω .
3-5 Measuring AC Current (A)
1. Rotate the function selector to the A
%
position.
2. Refer to figure 2 and disconnect probes from probe test points.
3. Place the conductor anywhere within the sensor zone as shown in the shaded areas of Fig. 2.
