Just checked my 238 tuner. With 10 watts applied, FWD/REF switch released,
2KW/200W switch released, POWER/SWR switch depressed, SWR set control max
clockwise, I get 1/2 scale on the meter.
Looks like it takes about 50 watts to get full scale under these conditions.

Obvious question - has he tried adjusting the "SWR Set" control to at
least 3/4 scale? Also, which scale is he looking at? If he's got it set
for SWR, and the antenna is alerady low SWR, obviously the meter is not
going to move up scale.
And what kind of transmitter is he using? Is it a QRP rig? With my 238
ten watts of RF from the transmitter will not get the SWR FWD reading to
half scale with the SWR SET at maximum sensitivity.
