23. Calculate the attenuation twice, using the formulas from the previous test. Refer to step 14.
24. Verify that the attenuation is in the range of 4.9 to 5.1. Record the results in the test record.
25. S lide the DC Reject switch on the probe to turn DC reject on.
26. Verify that the output returns to approximately 0 volts. (This is a functional check; there is no specified performance limit.)
27. S lide the DC Reject switch on the probe to turn DC reject off.
28. K eep the output connections for the next procedure.
