I got a 300E+ (firmware 4.52) a couple weeks ago and just noticed that the clock seems to get ahead of itself after a little time. From when I first set it (synced manually while looking at computer's clock, to make sure it was down to the second) until today, it was running about a minute ahead of actual time. Reset it with the same method, after less than an hour it was running about 15 seconds ahead of real time.
I don't use data logging so it's not the end of the world, but I'm curious about whether or not it's a firmware bug?
Hi PKIDelirium, the 300E+ has an external clock. Its accuracy is not exactly 100% that's why sometimes it's either late or advance for few seconds every hour or day. It is not a firmware bug.
