Performance The specifications that follow apply when the instrument is in the condition of
Conditions Enhanced Accuracy. Enhanced Accuracy is initiated by pushing the E A, button
on the specific host mainframe after the system has reached thermal equilibrium,
which requires 20 minutes warmup. Enhanced Accuracy is indicated on the CRT
display and remains in effect as long as the mainframe internal temperature
change is less than 5° C from the temperature at which the calibration was
performed. When the 5° C change does occur the accuracy condition becomes
Not-Enhanced. In the Not-Enhanced condition those Characteristics that are
temperature sensitive may not remain within the limits of these specifications.
The instrument specifications are valid at an ambient temperature of 0° to
+50° C, unless otherwise stated.

1For absolute DC accuracy of single-point measurements using Offset, add the DC Offset
Accuracy, DC Balance and AV DC Accuracy terms. Apply the AV DC Accuracy only to the
difference between the Vertical Position setting and the measurement point.
