Firmware Update
Use the following procedure to update instrument firmware:
Do not turn off the instrument during the update.
1. Press [Help] > About to determine what instrument firmware version is currently installed.
2. Go to www.agilent.com/find/truevolt and use the links there to find the latest firmware version. If this matches
the version installed on your instrument, there is no need to continue with this procedure. Otherwise, download
the firmware update utility and a ZIP file of the firmware.
3. Unzip the ZIP file and use the firmware update utility to prepare a USB drive with the updated firmware.
4. Attach the USB drive to the instrument front panel and press [Utility] > Test / Admin > Firmware Update to
update the firmware. If the security option is installed, unlock the instrument with the security code before
installing firmware.
