MEASURING RESISTANCE
The unit of resistance is
Ω
. The meter sends low current into the circuit so
that resistance can be measured. This current runs all the paths between
probes, and the measured resistance value is all values added among
them.

Description
DC Voltage test
AC Voltage test
Resistance test
(Measuring unit :
Ω
)
Voltage test
(Measuring unit : V)
Current test
(Measuring unit : mA, A)
Continuity test
(Starting to beep at below 80
Ω
)
How to measure : Connect the red
lead to and the black lead to ,
as shown in the figure above at left.
and measure the resistance directly
at the resistance measuring mode,
by pressing on the key pad.

TESTING CONTINUITY
Continuity means the presence of a complete path for current to flow. And
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.
How to test :The resistance mode returns to the continuity mode, when
is pressed. The beeper is activated when the resistance between the
red probe and black probe is below 80
Ω
.
