Diodetest; Continuity Test; Transistor Test; Spare Parts - Velleman DVM860BL Mode D'emploi

6.17. Diode Test
1. Connect the black test lead with the COM jack and the red test lead with the INPUT jack (the polarity of the red
test lead is "+").
2. Place the range switch in the
3. Press the FUNC. button to select the function "diode test"
4. Connect the red lead with the anode and the black lead with the cathode of the diode to be tested.
5. Read the value from the LCD.
REMARKS
• The LCD will display the possible forward voltage drop of the diode.
• The overrange indication "OL" will be displayed if the leads have not been connected properly.
• The overrange indication "OL" is displayed when the input is not connected e.g. in case of an open circuit.

6.18. Continuity Test

Deactivate the circuit to be tested and make sure all capacitors have been fully discharged prior to measuring the
circuit's continuity.
1. Connect the black test lead with the COM jack and the red test lead with the INPUT jack.
2. Place the range switch in the desired
3. Press the FUNC. button to select the function "continuity measurements"
4. Connect the test leads with two points of the circuit to be tested.
5. The built-in buzzer will sound if continuity exists.
REMARKS
• The overrange indication "OL" is displayed when the measured resistance > 200Ω or when the input is not
connected e.g. in case of an open circuit.

6.19. Transistor Test

1. Put the rotary switch in the hFE-position.
2. Plug the multifunction socket into the COM jack and the INPUT jack.
3. Identify whether the transistor is NPN or PNP type and locate the emitter, the base and the collector. Insert the
transistor leads in the proper holes of the multifunctional socket.
4. Read the value from the LCD.

7. Spare Parts

a) Batteries
WARNING
Disconnect the test leads before opening the battery compartment in order to avoid electroshocks.
The symbol is displayed if the batteries need to be replaced:
1. Disconnect the test leads from all live sources, switch off the device and remove the test leads from the input
terminals.
2. Unscrew the cover of the battery compartment and remove it.
3. Remove the batteries and replace them.
4. Replace the cover and tighten the screws.
Remark: Respect all applicable laws when disposing of your old batteries.
