Precise Impedance measurement:
1.
Insert an RED testing lead into “HI” socket and another RED testing lead into
the adjacent “RX” socket; insert a BLACK testing lead into “LO” socket and
another BLACK testing lead into the adjacent “RX” socket.
2. Select the function switch to 200 m
Ω
position.
3.
Short circuit the two testing clips, adjust “ZERO ADJUST KNOB” to a ”000”
reading value on the LCD.
4. Whenever a selected range of 200 m

5. To measure an unknown resistor RX then by following the two point type of
measurement per shown in figure 3.
