Measuring Resistance, Conductance and Testing Continuity
1 Set the rotary switch to Ω  nS.
2 Connect the red and black test leads to the input 
terminals  Ω  and COM  respectively.
3 Probe the test points (by shunting the resistor) and read 
the display. 
Figure 9 Measuring resistance
Disconnect the circuit power and discharge all high-voltage capacitors 
before measuring the resistance to any prevent possible damage to the 
meter or the device under test.
