[Elecraft] Calibrating K3 Wattmeter

[Doug Person]

On page 49 of the K3 Owners there is a procedure for calibrating the 
K3's watt meter.  The 6th step reads "Hold TUNE; adjust menu parameter 
for a reading of 5.0 on the external watt meter".

My question is adjust WHAT to adjust the menu parameter.  Certainly not 
the main tuning like how every other parameter is adjusted.  This has no 
affect on power output.
