Model 6517B Electrometer Reference Manual
Power-up error messages
The Model 6517B performs the following checksum tests on power-up.
Data
IEEE-488 address
Power-up default
Calibration constants
Calibration dates
Instrument setups
Reading buffer
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
Error -314
Error +510
Error +511
Error +512
Error +514
Error +515
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.

Description
Save/recall memory lost
Reading buffer data lost
GPIB address lost
Power-up state lost
Calibration lost
Calibration dates lost
Action
Instrument setup is reset to bench defaults are
stored in EEPROM.
The reading buffer controls are reset to factory
defaults, but they are not stored into NVRAM. To do
this, store readings in the buffer.
GPIB address is reset to factory default (27) and
stored into EEPROM.
Power-up defaults are reset to factory defaults
(bench) and stored into EEPROM.
Cal constants are set to factory default values, but
they are not stored into EEPROM. To do this,
perform a comprehensive calibration.
The cal dates are set to factory default values, but
they are not stored into EEPROM. To do this,
perform a comprehensive calibration.
