Setup Menu Screen
The “Setup” menu allows the setup of system functions such as Alignment,
Remote Setting and System Password. All of these menu items will direct you to
a sub-screen with the pertinent options and details, with the exception of “Non-
Align” which is simply a state toggle. The remaining functions outlined below
are explained in further detail.
Note: The “Non-Align” function enables a forced operation override of the
7520 such that the device will allow operation in a “Non-Aligned” therefore
uncalibrated state. This is intended for demonstration and training purposes
and should never be used for official measurements. If during “Non-Align”
mode voltages higher than 25 V have been used, self-alignment should not be
invoked for 6 hours to allow the resistor chain to cool to its nominal
temperature.
The “Self-Align” will invoke the Self Alignment process after the system has
reached temperature stability of the internal chamber.
The “Password” allows the changing of the system password to protect the
calibration integrity of the instruments from possible unintended change.
The “Offset Adjustment” allows a direct adjustment and view of voltage ratio
adjustments if utilized by the operator.
The “System Parameters” allows the setting of things such as GPIB address, Date,
and Time.
