Hey I tried to send you a PM but was unable to. This pertains to the UM24C I've run into an issue that may have been there since day 1 but i am unsure. When i have it in data slowt 1-8 9 times out of ten it will not retain the data upon power cycle. And when it does (rarely) it only retains the Capacity and not Energy data. I have tried to see if there was a way to make it fail or work consistently and I've had no luck. I try to stop the recording before disconnecting, I've tried to unplug the load before powering off, etc. I also notice that many times even the data slot 0 won't retain the data upon reboot. I do know it overwrites the second recording is started but it rarely even saves that. Any input? Thanks Dave |
