Measurement status notes
Whenever a fault occurs, run the Confidence Check utility before performing any other
troubleshooting actions (see
Measurement timeout: Indicates that the measurement was not received after a set time (total
aperture). This timeout error may indicate that there is an issue with the 4210-CVU card. Try resetting
the hardware and running the project test again. If this error reoccurs, contact Keithley Instruments.
To reset the hardware:
1. Select Start.
2. Type resethw.
3. Select the instruments that need reset.
4. Click Reset.
I measurement overflow: Try a higher I measure range (or Auto) or try a lower AC drive voltage.
V measurement overflow: Try a lower DC bias voltage.
ABB not locked: Auto Balance Bridge was not locked when the measurement was made. The
readings and calculation results may not be accurate.
