Power-up error messages
The Model 6517B performs the following checksum tests on power-up.
Data Type of storage
IEEE-488 address Electrically-erasable PROM
Power-up default Electrically-erasable PROM
Calibration constants Electrically-erasable PROM
Calibration dates Electrically-erasable PROM
Instrument setups 10 in electrically-erasable PROM
Reading buffer Non-volatile RAM
The error messages that may be displayed during the power-up sequence are summarized in
the following table. These are shown when one of the checksum tests fails.
Message Description Action
Error -314 Save/recall memory lost
Instrument setup is reset to bench defaults are
stored in EEPROM.
Error +510 Reading buffer data lost
The reading buffer controls are reset to factory
defaults, but they are not stored into NVRAM. To do
this, store readings in the buffer.
Error +511 GPIB address lost
GPIB address is reset to factory default (27) and
stored into EEPROM.
Error +512 Power-up state lost
Power-up defaults are reset to factory defaults
(bench) and stored into EEPROM.
Error +514 Calibration lost
Cal constants are set to factory default values, but
they are not stored into EEPROM. To do this,
perform a comprehensive calibration.
Error +515 Calibration dates lost
The cal dates are set to factory default values, but
they are not stored into EEPROM. To do this,
perform a comprehensive calibration.
Any of these error conditions may occur the first time a unit is turned on or after replacing the
firmware.
Power-up default conditions
Power-up default conditions are those conditions the instrument assumes when it is first turned on.
You can change these power-up default conditions (except the primary address) by using the save
setup feature that is available with the MENU key.
Warmup period
You can use the Model 6517B within one minute after it is turned on. However, the instrument should
be turned on and allowed to warm up for at least one hour before use to achieve rated accuracy.
