EXTENDED RANGE PUSHBUTTON (+10 dB PAD)
------
This pushbutton is used to store the calibration data in the
EEPROM. After the calibration data is stored the EEPROM checksum
will be updated. If the calibration data can not be stored
properly after attempts, the word "CAL" will be flashed on the
HL and then the previously displayed value restored. If this
error occurs the calibration may still be continued for other
stimuli.
SWITCH RESPONSE
- - -
This switch is not used during the attenuator maximum output
level calibration and all operations will be ignored.
HL DISPLAY
- - - - -
This display is used to display the attenuator position in the
range of 0 to 255 as selected by the HL selector. It will be
displayed in a right justified,
integer format on digits 1, 2 and
3.
LED RESPONSE
This LED is used to indicate the correct storage of calibration
data in the EEPROM when the Extended Range Pushbutton is
operated. This LED is normally OFF and will be turned ON for 2
seconds after the calibration data has been stored and verified.
If the data is not stored correctly, the LED will remain OFF and
the word "CAL" will be flashed on the HL display and then the
previously displayed value will be restored.
STIMULUS ON LED
This LED is used to indicate stimulus presentation. The LED is
OFF when the stimulus is not being presented and on when it is
being presented.
LOW
SEGMENT
This LCD segment indicates a low battery voltage condition.
SEGMENT
This LCD segment will be OFF to indicate that the position of the
+10 dB pad is out.
