Hi there,

I'm using two loggers, one DT80M Series 3 and one Series 4.

I know that I can switch the isolated 5V power output on using the command:

PWR5V=1

However, this setting is not persistent and vanishes after a logger looses power (and the backup battery is down). Is there a way to switch 5V power on using one of the profile parameter settings, making it thus persistent?

I know this case will not often occur, but we install loggers that cannot be maintained for up to 12 months, and thus it's always possible that the backup battery fails and we have intermittent power outages.

As far as I understand the manual, P21 only controls the 12V power output, but not the isolated 5V output.

Any help/advice is greatly appreciated

Best regards

HI Maximilian,

Please enable continuous power to analog circuit, P21=1 in addition to PWR5V=1.
