A D(u)MM question

<< < (3/3)

RoGeorge:
mtx3283, too, can display dBm and W for an R value of your choice between 1-10000 ohms.

electr_peter:
Agilent/Keysight U1272A handheld DMM also has dBm (reference 1-9999 Ohm) or dBV (reference 1V) display option.

--- End quote ---

Yes, very easily.  If you just apply 2.828VAC and press SHIFT then NULL(dB) the 34401A will then read dBW/8R, or 0dB for 1W with 8R impedance and so on.  But I think the OP was looking for watts displayed directly and that is a pretty niche feature.

shakalnokturn:
Escort 97 will display in dBm, Voltcraft GDM705 in dB but neither has a Watts option.
