• The entire LCD (buttons and digital display) will be turned momentarily ON
and OFF.
• The number "88888" will be displayed.
• The display will show either EPASS or EFAIL, following a checksum per-
formed on the EEPROM where program parameters are stored. If EFAIL
appears, it means that there is a difference between the calculated checksum
and the stored checksum. IN THE EVENT OF AN "EFAIL" MESSAGE, CON-
TACT THE FACTORY CUSTOMER SERVICE DEPARTMENT FOR INSTRUC-
TIONS.
• The display will show either rPASS or rFAIL, following a modified "walking bit"
test performed on the RAM chip. If rFAIL appears, it probably means either
that a RAM write did not take or that a write to one location affected another
byte of the RAM. IN THE EVENT OF AN "rFAIL" MESSAGE, CONTACT THE
FACTORY CUSTOMER SERVICE DEPARTMENT FOR INSTRUCTIONS.
• The display will show either cPASS or cFAIL, following a checksum per-
formed on the code PROM. If cFAIL appears, it means that the calculated
checksum was different from the stored checksum. IN THE EVENT OF A
"cFAIL" MESSAGE, CONTACT THE FACTORY CUSTOMER SERVICE DEPART-
MENT FOR INSTRUCTIONS.
• The instrument model number will be displayed.
• The instrument software version will be displayed.
• "Live" numeric data will be displayed.
