Description of menu functions
PROGRAM
1. “Program>Quit” – To quit the program.
Rework/ Get UUT Info
1. “Rework > Get UUT Info > ID number”- shows the production process ID number.
2. “Rework > Get UUT Info > Manufacture date”- shows the unit’s production date.
This is created in production during the VPT calibration process.
3. “Rework > Get UUT Info > Service date”- shows the unit’s service date. This is
created whenever there is any save to the UUT’s EEPROM.
Rework/ VPT Tests
1. “Rework > VPT Tests > Download Constants”- Downloads the VPT constants.
2. “Rework > VPT Tests > Check VPT calibration”- Check on the correctness of the
VPT calibration using calculation based on the RGB characterization data. To be used
with a white pattern setting.
3. “Rework > VPT Tests > Get Checksum Data”- To check if the RGB characterization
data in the EEPROM is correct
4. “Rework > VPT Tests > Get Max RGB Ik”- Show what are the max RGB beam
currents stored in the VPT EEPROM.
5. “Rework > VPT Tests > Get Magic cookie”- Show what is the unit’s unique ID. This
unique ID must matched the unique ID stored in the EDID data.
6. “Rework > VPT Tests > Get Coulomb Counter”- Show what is the amount of aging
the CRT has gone through. This is updated at about every 35mins interval.
7. “Rework > VPT Tests > Zero Coulomb Counter”- Reset the aging counters. Used
only when set is serviced and it is also automatically zeroed during the VPT
calibration process.
8. “Rework > VPT Tests > Perform VPT characterization”- Perform VPT calibration
using a serially controlled CA100.
Rework/ White Balance
1. “Rework > White Balance > Align White Balance”- Perform the white balance
adjustment using a serially controlled CA100.
Rework/ EDID
1. “Rework > EDID> Download Default Constants”- Downloads the default EDID
constants.
2. “Rework > EDID> Copy Magic Cookie”- Copy the magic cookie number from VPT
EEPROM to EDID data EEPROM.
3. “Rework > EDID> Get EDID ID”- Shows the magic cookie number that is stored in
the EDID EEPROM. Must be the same as the number shown in the “Get Magic
Cookie”.
4. “Rework > EDID> Upload EDID To File”- Uploads the EDID data and stores the
data in simple text file format.
