Test Connection Diagram

Fluke 9500B

Test Procedures

1. Connect the active head of Fluke 9500B to CH1 of the oscilloscope, as shown in the figure above.
2. Turn on Fluke 9500B and set its impedance to 1 MΩ.
3. Output a DC signal with +3 mV
4. Configure the oscilloscope:
1) Press CH1 in the vertical control area (VERTICAL) on the front panel to turn on CH1.
Press CH1  Probe to set the probe attenuation ratio to "1X".
2)
Rotate VERTICAL
3)
4) Rotate HORIZONTAL
Press VERTICAL
5)
Press Acquire  Mode and use
6)
and use
7) Adjust the trigger level to avoid that the signals are being triggered by mistake.
Press MENU  Vavg at the left side of the screen of the oscilloscope to turn on the average

measurement function. Read and record Vavg1.
6. Adjust Fluke 9500B to make it output a DC signal with -3 mV
Press MENU  Vavg at the left side of the screen of the oscilloscope to turn on the average
7.
measurement function. Read and record Vavg2.
8. Calculate the relative error of this vertical scale: |(Vavg1 - Vavg2) - (Vout1 - Vout2)|/Full
Scale × 100%.
9. Keep the other settings of the oscilloscope unchanged:
1) Set the vertical scale to 2 mV/div, 5 mV/div, 10 mV/div, 20 mV/div, 50 mV/div, 100 mV/div,
