  6. Copy or "click and drag" all 6 folders to an EMPTY USB flash drive (The smaller the flash drive the better - 2GB is preferable.
  7. Once the 6 files are transferred to the flash drive, safely eject the USB from your computer.
The Update files are now on the USB upgrade drive.

Proceed with updating the meter with the software on the USB upgrade drive with the instructions below:
  1. Make sure the meter is turned off. Disconnect any probes from the meter.
  2. Connect the USB/DC power adapter to the meter and to the AC-DC power supply. Connect the AC-DC power supply to the power cord.

  4. Plug the AC power cord into an electrical outlet.
  5. Turn on the meter. The software upgrade will automatically begin. The meter will display “Updating to HQd_xx.mot” and then display the logo. Wait for the meter to beep (approximately 15 seconds).
  6. After the meter beeps, remove the USB flash drive from the USB/DC power adapter. The meter will power off.
  7. Turn on the meter. Verify that the software version (HQd_xx.mot) that is displayed on the meter matches the software version that is displayed on the upgrade drive.
Note: The software version is displayed when there are no probes connected to the meter. The software version can also be displayed by pressing OPTIONS and selecting Meter Information.

If the meter does not recognize the software in step 5, please try a different brand or size of USB flash drive.
