Is there any software to help me get started

Yes. Keithley provides Keithley KickStart and Keithley TestScript Builder to help you get started with
the DMM6500.

Keithley KickStart is a software program that allows you to set up your instrument and run a test
without using any programming languages.

Keithley TestScript Builder (TSB) is a software tool that simplifies building test scripts if you are using
the Test Scrip Processor (TSP

) scripting engine.

Both software options are available on

How do I upgrade the firmware?

Do not turn off power or remove the USB flash drive until the upgrade process is complete.

The firmware file must be in the root subdirectory of the flash drive and must be the only firmware file
in that location. You can upgrade or downgrade the firmware from the front panel or from the virtual
front panel.

From the front panel:

1. Copy the firmware file (

.upg

file) to a USB flash drive.

2. Verify that the firmware file is in the root subdirectory of the flash drive and that it is the only

firmware file in that location.

3. Disconnect any terminals that are attached to the instrument.

4. Turn on instrument power.

5. Insert the flash drive into the USB port on the front panel of the instrument.

6. From the instrument front panel, press the

MENU

key.

7. Under System, select

Info/Manage

8. Choose an upgrade option:



To upgrade to a newer version of firmware, select

Upgrade to New



To return to a previous version of firmware, select

Downgrade to Older

9. If the instrument is controlled remotely, a message is displayed. Select

Yes

to continue.

10. When the upgrade is complete, reboot the instrument.

A message is displayed while the upgrade is in progress.

Upgrade files are available on
