Test Procedures
1. Connect the active head of Fluke 9500B to CH1 of the oscilloscope, as shown in the figure above.
2. Configure the oscilloscope:
1) Press 1 in the vertical control area (Vertical) on the front panel to enable CH1.
2) Press 1  Impedance to set the input impedance of CH1 to 1 MΩ.
3) Set the vertical scale of CH1 to 100 mV/div.
3. Turn on Fluke 9500B; set its impedance to 1 MΩ and select the resistance measurement function.
Read and record the resistance measured.
4. Adjust the vertical scale of CH1 of the oscilloscope to 500 mV/div; read and record the resistance
measured.
5. Turn off CH1. Measure the resistance of CH2 using the method above and record the
measurement results.
