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 password-protected (see Section 6.5.3,
Password on page 62). In order to access the parameters within this function you must
enter the correct four-digit password. (See Figure 45 on previous page.)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.
By default the password is set to '1529' when the instrument ships from the factory.
We recommend that the user change the default password to protect the password-
protected settings.
Note: Keep your password in a secure location and do not forget it.
To enter the password, press the Enter button. Press the LR buttons to highlight
the digit to change. Use the UD buttons to scroll through the numbers 0-9. Press the
Enter button to save the new setting. Press the Exit button to cancel and to exit to the
menu.
If an incorrect password is entered, the display shows the message PASSWORD
INCORRECT and access to the password-protected parameters is denied. Press the
Enter button to return to the menu. If the correct password is entered, the bottom por-
tion of the display allows the user to select the channel to view.
Figure 46
Each channel of the 1529 is calibrated independently and therefore each channel has
its own set of calibration parameters which are displayed after the CAL CH parameter
is entered.
