Fig. 5-12 Power On
The following start up sequence will begin:
1. The PASS and FAIL test LEDs will illuminate. The LCD back
light will be on but no messages are present.
2. After approximately 30 seconds the buzzer will sound and
the 6 test LEDs will illuminate in sequence.
3. For the keypad version of the GDU net , the display will show
‘Enter ID then #’, enter the user ID to continue.
4. The ‘INSERT INSTRUMENT’ test LED will be illuminated and
the LCD only now will display the message ‘GDUnet #010001
INSERT GMI’.
(#010001 - example serial number of a GDU
net .)
5. The GDU net is now ready to test / calibrate instruments.
Keypad users have 10 seconds to test / calibrate an instrument
before the GDU net reverts back to ‘Enter ID then #’.
Note: The start-up sequence gives the opportunity to
observe the test LEDs and buzzer are functioning
correctly.
