6. Make a linear regression with these 5 data points:
Offseterror1~Offseterror5, Offsetout1~Offsetout5. Check to verify that
the slope is within the limits specified in Table 4 .
7. Check to verify that abs(Vzero) in step 4 is within the limits specified
in Table 4 .
8. Set the oscilloscope Volts/Div to the other settings in Table 4 , and
repeat the steps 4 to 6.
9. Turn the 9500B output off.
10. Disconnect the connections to all the channels.
