# CAUTION
Make the zero ohm adjustment after every change of the
measuring range to obtain a more accurate reading.
Application:
Checking a resistance value of resistors, circuit continuity, short and
open circuits, etc.
⑴ Insert the red test lead into the +terminal and the black test lead into
the −COM terminal.
⑵ Set the range selector switch to the desired range position.
⑶ With the test lead tips shorted together turn the zero ohm adjust
knob so that the meter pointer lines up with the zero mark at the right
end of the ohm scale.
⑷ Turn off power to the circuit under test.
⑸ Connect the test leads to both ends of the circuit under test and take
the reading (Fig. 2).
