7.5.4 Calibration
The CALIBRATION function is used for accessing parameters and functions
related to the 1529 calibration. It first displays the date the current calibration is
due and the date the instrument should be recalibrated. Typically, all channels
should have the same due date. However, in the case that all channels do not
have the same due date the earliest date is displayed. This function is pass-

function you must enter the correct four-digit password. When this function is
selected, the bottom portion of the display prompts the user to enter the current
password to gain access to this option.
