3.5 Measuring resistors

1. Move the function switch to position

.

2. Point the selector to the desired position.
3. If the resistance to be measured is connected to a circuit, turn off the power and

deactivate it before applying the probes.

4. Connect the probes to the resistor, read the value on the display.

3.6 Measuring diodes and continuity tests

1. Move the function switch to the position

2. Move the selector to the position with the diode symbol.
3. Connect the red probe to the diode anode and the black probe to the cathode, read the

measurement on the display in mV.

4. Connect the probes to two points of the circuit, a beep indicates if the resistance is

lower than 30
