9500B
Calibration Manual

When you select target 2 by pressing its soft key, the Target Amplitude and Frequency
will be displayed below the current Output Amplitude as shown in the following
Adjustment screen illustration:
erw228
If you now wish to change the calibration point frequency, this must be done by editing
the Frequency setting.
To do this, first transfer cursor control to the Frequency setting via the Tab
Δ
key. Then
alter the frequency setting using the same digit edit (cursor controls/spinwheel) method or
direct edit (numeric keypad) method used to change Output and Target Amplitude.
Note
Limits are placed on the extent to which the Frequency value can be
changed. In our example at 1.0000 kHz, the frequency cannot be set above
1.0500 kHz, nor below 0.9500 kHz. Beyond these limits the error message
'Outside frequency range' is given.
Once the target has been saved, the new saved Frequency will be shown as well as any
new saved Target Amplitude on the Target Selection screen, when the 'DEFAULT
TARGETS' soft key label is not highlighted. Calibration can now continue as detailed in
Calibrating the Model 9500B at Target Values.
Exit from Base Calibration - Cal Date and Cal Due Date
Once all calibration has been completed, you will wish to return to normal operation,
which requires a short 'exit' process. The normal means of exit from Calibration mode is
to press the Mode key on the right of the front panel. When you do this, the 9500B will
present a Warning screen to indicate that the 9500B calibration may have changed, and to
offer you the following options:
•
Altering the date-stamp on any directly printed results certificate (or not)
•
Entering or altering the calibration due date
•
Indicate the advance warning period required before the cal due date
The following paragraphs show the screens, required actions and consequences.
