To reload or update firmware, first contact Technical Support to obtain the applicable

file(s): [email protected] /+1 800-324-5190.

1. Follow Technical Support’s instructions for copying the firmware files to a

flash drive.

2. Go to the Utilities>USB Utilities>General menu.

Figure 5-3. Manual Update Page (and other utilities)

3. Insert a flash drive into a front panel USB port and wait for the Status field to

indicate that the drive has been detected.

4. In the Update Firmware field, press the Check button for the instrument to

determine whether the firmware on the flash drive is more recent than what is

currently installed. Once it’s been determined that the firmware is new, the

Install button will be enabled; if the firmware version on the flash drive is the

same as or older than the current firmware of the instrument, the Install

button will not be enabled.

5. Press the Install button, and note the messages in the Status field at the

bottom of the page. Use the Cancel button if necessary.

6. When complete, as indicated in the Status field, press the Done button,

which replaces the Cancel button, and remove the flash drive.

7. Power off and restart the instrument to complete the new firmware

installation.
