）

1. Turn the function/range selection knob to Ω, insert

the red and black test lead separately to VΩHz and

COM input terminal.

2. Connect the test

lead to the tested

resistance

in

parallel, the tested

resistance

value

will be displayed

on LCD

3. Auto Range mode

is preset when turning on, press “RANGE” button to

switch to Manual Range mode.

4. If “OL” is displayed on LCD, it indicates the tested

resistance value has exceeded the present range limit,
