Hi Folks,

I've had this on my shelf longer than I can recall, so it's time to pass it on.  The meter is a Simpson rectifier type, unknown model number.  It says zero power level is 6mw into 500 ohms.  Zero on the scale is also marked 1.732 V.  I tested it with a 600 ohm source and it took 13.3dBm to reach zero.  Since the scale goes to +6, that is nearly +20dB full scale!

Outside dimensions are 4 5/8" x 4".  The meter is in very nice condition with just one tiny scuff on the lower left of the clear plastic.  It comes in a Simpson box (from another meter) with a mounting template on the bottom.  I will short the terminals to protect the movement during shipping.

$30 plus shipping from Brooklyn, NY 11222
