A look at the Uni-T UT210E

Does anyone know (or could measure) the value of the resistor R7 (where we get the current signal to the analog output)? I think I damaged the resistor and it does not pick up solder.  |O |O :palm:

Got a pic?  I can but I'm not sure where R7 is.

470 ohm

Thanks BiOzZ.

looking at some pictures, I think I found the value. The resistor is marked as 471 (470ohms).

Hi,

I did the modification and worked fine. In the future, I will try to add an active filter to limit the bandwidth and noise on small signals.

Maybe using one OPA2344 and one additional switch (I don't know where) would be possible to select between two cutoff frequencies.
