2.6 Resistance Measurement
WARNING
Never try to make measurement on a circuit that is not de-energized.
(1) Set the Function Selector switch to the "
" position. The "Ω" should
be shown on the upper right corner of the display.
(2) Slide the terminal cover to the left. Plug the red test lead into the Hi
terminal and the black test lead into the Lo terminal.
(3) Check that the display reads "OL". Then, short the tip of the test leads
together and check that the display reads "0".
(4) Connect the tip of the test leads to the circuit under test and take the
reading on the display.
NOTE
● When the tip of the test leads is shorted together, the display may read a
very small resistance instead of "0". This is the resistance of the test leads,
not fault.
●If one of the test leads has a break, the display reads "OL".
2.7 Continuity Check (400Ω range fixed)
