The electrical tester can be used for measuring the current, voltage, and resistance of an electrical circuit, as well as to check the continuity of a circuit and testing diodes.
The following measurements can be performed by operating the function selector switch:
Alternating current voltage measurement
For measuring the voltage of household or factory power supply lines, alternating current voltage circuits, and the tap voltages of a power transformer.
Set the function selector switch to the alternating current voltage measurement range and connect the test leads. The polarities of the probes are interchangeable.
