FUNCTIONAL SPECIFICATION
FUNCTIONAL SPECIFICATION
Measuring AC & DC Voltage
Voltage is the difference in electrical potential between two points.
The polarity of an AC voltage varies with time, while DC polarity is constant.
The meter displays AC voltage as RMS values (Root Mean Square readings).
The RMS value is the equivalent DC voltage measured in a time varying
sinusoidal signal.

Measuring Resistance
The unit of resistance is the Ω . The meter sends a low current into the circuit so that
the resistance can be measured. This current runs along all paths between the two
probes and enables the total resistance to be calculated.
Continuity Testing
Continuity means the presence of a complete path for current to flow. The
continuity test features a beep that sounds when a circuit is complete. The beep
allows users to quickly test continuity without having to watch the display.
The beeper is activated when the resistance between the red and black probes is
less than 80
Ω .
