- Check battery or battery
- Enjoy the power of a socket
- Check the condition of the equipment
- Test an electrical device
The multimeter measures the voltage (continuous or alternating) in volts, amperage current, and resistance in ohms. This handy diagnostic tool consists of a housing (with a switch) and two cords (one red and one black). The switch is used to set the type of measurement to be made and the sensitivity of the device. The test is performed by touching the circuit concerned with the pins that extend the cords.
Check battery or battery
To check the charge status of a battery (car or cordless), touch the contact terminals: red on "+", black on "-". The value is displayed on the meter display.
Enjoy the power of a socket
The control of electrical outlets makes it possible to appreciate the presence of the current, the quality of the circuit and its continuity.
Press the spikes into the socket, then observe the reactions on the screen.
Check the condition of the equipment
The multimeter tests a wide range of low voltage electrical currents.
It can be used to check the condition of the equipment: if a fuse has blown or if a bulb is blown.
Test an electrical device
To find out if a device is down, first test the socket then the device, the switch in the "on" position.
If the resistance is "infinite" or if the display shows "OL" (as here), the unit has a fault.
