10. Calibration

This section covers L-Series calibration using the LSGUI program as a
support tool.

10.1 Calibration support features

L-Series instruments require regular calibration to maintain performance
specifications. As a general rule, annual calibration of the output and the
measurement system is recommended. The LSGUI program, while not
specifically designed as a calibration program, can be used to assist with the
calibration process. Specifically, it can be used to set the required outputs
automatically and also provides on screen references to the required
calibration points. For users who require historical calibration data for
statistical process control (SPC), the LSGUI allows existing calibration
constants to be saved to disk prior to each calibration procedure.

10.2 Unlocking calibration screens

Both the measurement and the output calibration screens are lock out
from the operator unless the calibration password is known. The calibration
password is printed on the original distribution disk and should be made
available only to qualified personnel.
To unlock the calibration screens, position the cursor in the "Calibration
Unlock" - "Password" field located at lower left corner of the System Settings
screen. Remove the five '*' characters and type in the calibration password
followed by the 'ENTER' key. If the 'ENTER' key is not pressed, the
password will not be accepted. A beep will sound and both the 'Output Cal'
and 'Meas Cal' buttons will be enabled.
