Instruction
1
Check the diode.
Check for a faulty diode. To do this put the multimeter in continuity test mode or resistance measurement. Insights diodeand should not be attached to any equipment. Touch the probes of the findings of the diodeand then adjust the location of the probe and retry the operation. Serviceable diode should zvonnitsa in only one direction. Remember or label the output, which touched the probe of positive polarity, at a time when the diode is to be called an. This pin is called the anode.

Mounting the diodein the circuit of alternating current.
Do not break in the AC circuit, by cutting the wire or disconnecting it from the terminals of any electrical appliance. Strip the wire ends and solder them with a soldering iron. Insights solder the diodeand to the resulting ends, or if design allows the diodeand connect the wire using bolt connections.

Mounting a diodein a DC circuit.
Do not break in the electric circuit, strip and solder the ends of the wires are obtained. Determine the polarity of the voltage in a circuit where you intend to install the diode. This can be done with a multimeter in the measurement mode of the DC. Touch the probes to the ends of the wires, to created an open circuit. If the readings on the display are negative, then the negative or common probe is on a wire with a positive polarity. If the reading is positive, then the positive probe touches the point with the corresponding polarity. Determine the polarity of the diodeand in electrical circuit. If a diode is used as the conductive element, then connect the anode side of a point with a positive voltage. When using a diodeas a locking element, the anode is attached to the negative electrical circuit. Solder or otherwise connect the insights diodeand the portion of the circuit.

Note
All operations with the installation and dismantling of equipment should be carried out with completely de-energized circuit.
Useful advice
Before installing the diodes, verify that the electrical parameters, such as allowable current and voltage correspond to those in force in the used electric circuit.
