4.2.60 Set the external power supply to + 10.0 VDC ± 0.02 volts as the display
structs, press
enter.
Set the supply to +11.8 VDC ± 0.02 volts when the
play instructs, press
enter.
Verify that the test passes. Turn the monitor off.

POWER
button on the front panel. Verify that the monitor powen
and passes the self test, then resumes normal operation. Plug the TB5(
Sensor Simulator into the front panel sensor socket.

Production Test Software
This section describes the special "Production Test Software" used in c
brating and troubleshooting the monitor. To access this software refer to ;
tion 4.5.
MONITOR TEST 01- "Automatic Test", monitor tests 02 thru 06,
and 10 are automatically ran in sequence. If any failures are encountered
monitor will stop at the particular test number that failed. For example, if
03 failed then the monitor will stop at "M0NITOR TEST 03".
MONIT0R TEST 02- "RAM Test", test RAM from A000H to 0H
by writing 55H and then AAh to each RAM location and reading it back,
tests each data bit.
MONIT0R TEST 03 - "ROM Checksum test", checks the calcuh
checksum of the EPROM against that value stored in EEPROM, if the val
are different the monitor must perform an auto calibration before it can run i
mally. This will occur if the system software has been changed to ensure
front end is calibrated with each revision level change in software.
