Boonton 92B use simple diode detector but squeeze most of it:  flat power response, literally, by shaping the diode response  (by convert knee/linear detector to square root response), as while achieve a respectful accuracy.

Come with Broken Glass

Delivery is the same all over the world,  they have always broken your favorite device, and the seller never knows what good packaging means. This beauty came with broken glasses,  and very lucky, the needle still working. 

It deserves a careful fix. I have several ruined HP-435,  that glass is almost perfect for this meter, except the glass need shaping to fit this meter face. The mini hand mill, similar to DREMEL, could cut the glass easily,  and always with a 3M mask.

The needle is slight been beend, this kind of problem need fix with a wider leg tweezer,  and gently bend it to another direction. and finally I managed to fix it, cool.
