Trying to upgrade the firmware of EM3500 meters. It seems I can use DLF-3000 (after verify the meter can be upgraded at field). The only version I can find for DLF-3000 is V3.3.2. It doesn't list EM3500 meters. Not sure if I need a newer version of DLF or I need driver for EM3500 for DLF. Please let me know. And where I can download them.
Also if you can kindly point me to the location of newer version of firmware for EM3500, that'll be great.
