Make sure the switch in the Accessories cable is away from the instrument. Start the DLV1210.exe program. Hold the ON switch down on the instrument while you open the CI_340V5xxx.s19 file with the DLV1210.exe program. After about 15 seconds, the instrument should display DLC.

If DLC is not displayed, run the DLV1210.exe program a second time while holding the ON button down on the instrument.
