4.8 Resistance Measurement
Automatic measurement ranges: 400Ω to 40MΩ (6 ranges)
Note: When making a resistance measurement, make sure that the
power is off (dead circuit). It is also important that all capacitors in
the measured circuit be fully discharged.
• Turn the rotary switch to the range
• Insert the red lead to the red “+” input jack and the black lead to
the black "COM" input jack
• Bring the test probe tips into contact with the sample under test
Warning:
If overload “OL” is displayed, the resistance exceeds the
measurement range or the circuit is open.
