MULTIMETER
-
A multimeter is used to measure voltage, current, resistance, and for testing continuity, diodes, and sometimes capacitance or frequency.
-
There are two main types — Analog Multimeter and Digital Multimeter (DMM).
-
The symbol V⎓ means DC Voltage, and V~ means AC Voltage.
-
“OL” means Over Limit — the resistance or voltage is beyond the selected range, or the circuit is open.
