How good is your coax?  Maybe you have some problem connections when 
used at 6m if you are not getting even relative readings.  My TT 1225 
was well agreeing with Bird instruments at even 2 meters.  A near 
electrical length of coax as a jumper may be the problem at 6 or 2 meters.

For Field Day with a brand new cross needle meter, we were having SWR 
dip problems, the tuner seemed too touchy.  Adding 10 feet of coax to 
the feed line cured the apparent unusual current or voltage condition 
and moved the metering point out of a critical peak point on the total line.
