1. Using the Range Down function, decrement the
amplitude of the 3314A to the values shown in
Table 4-4. each time recording and comparing the
measured Offset to its corresponding limits.
J. Set the amplitude on the 3314A to 10V and adjust
the DC offset to O.887V.
K. Record and compare the DC Offset measured on
the Digital Voltmeter to the limits given in the ap-
propriate section of Table 4-4.
L. Repeat step I for the offset of O.887V.
M. Set the amplitude of the 3314A to lOV and adjust
the DC offset to -O.887V.
