1. Connect the red test lead to the " V Ω
" terminal
and the other (black) test lead to the "COM" terminal.
2. Set the rotary function selector to "
" position.
3. Connect the test leads to the circuit to be measureu .
The biszzer will sound if the resistance of the circuit
measured is lower than 30g.
1. Set the rotary switch at "
" position.
2. Connect black test lead to "COM" terminal and red
lead to "
V Ω
" input terminal.
3. Connect test leads to the diode normally the forward
voltage drop of good silicon diode is shown between
400V to 900V. If the diode under test is defective .
"000" (short circuit) or "OL" (non-conductance) is
displayed. Reverse check of diode if the diode under
test is defective ''000" or other value are to be
displayed.

WARNING
1. Connect the red test lead to the " V Ω
" terminal and
the other (black) test lead to the "COM" terminal.
2. Set the rotary function selector to "Ω" position to
measure the resistance.
3. For correct reading , ensure that the device being
tested contains no voltage.
4. Connect the test leads across the resistor to be
measured. In order to ensure the best accuracy in
measurement of low resistance, short the test leads
before measurement and memory the test probe
resistance in mind. This necessary to subtract for the
resistance of the test leads themselves.
