A multimeter, also known as a volt-ohm meter, is a handheld tester used to measure electrical voltage, current (amperage), resistance, and other values.
When the knob is set to 20V DC, the tester will detect DC (direct current) voltage up to 20 volts.
To measure smaller voltages, you would set the knob to the 2V or 200mV range.
