Power-up error messages
Message Action
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.
Error +514,
DC calibration data lost
DC cal constants are set to factory default values, but they are not stored into
EEPROM. To do this, perform a comprehensive calibration.
Error +513,
AC calibration data lost
AC cal constants are set to factory default values, but they are not stored into
EEPROM. To do this, perform a comprehensive calibration.
Error +512,
Power-on state lost
Power-on defaults are reset to factory defaults (bench) and stored into EEPROM.
Error +511,
GPIB address lost
GPIB address is reset to factory default (16) and stored into 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 -314,
Save/recall memory lost
Instrument setup is reset to bench defaults and stored into EEPROM.
Notes:
1. Any of these error conditions may occur the first time a unit is turned on or after replacing the firmware.
2. Error +510, Reading buffer data lost, applies to units with optional memory.
3. Error +512, Power-on state lost, may occur the first time the unit is powered-up after replacing the MEM2 memory option with MEM1.
