Hey there ,
I got a transformer that is 25-25-0 plus 12-12-0, both em are dual output i need to know if i can just connect em in this same order to get more voltage ik, at the end the total watts will be the same, and if that's possible, is this safe?

We are trying to determine if the 12 V windings and the 25 V windings are galvanically isolated. What is the resistance between one of the 25 V wires and one of the 12 V wires?
Version A cannot be adapted for various voltages, version B can be added to get higher voltage. Measuring resistance from zero to zero on A will be a short, on B it will be infinite.

For the low frequency, mostly-sine-wave output of an unloaded mains transformer, this is not an issue. In fact, this probably is what the meter is calibrated for.
All multimeters are designed to read the RMS voltage of a sinewave.
Since this is a transformer sine-wave output, whether the meter is average responding, calibrated to read RMS, or a true RMS meter will have a negligible difference on the value measured.
