Well, I've tried very, very many variations...
Either it has no change to te pic above in position or there is no meter at all...
My actual try: (with and without TB_right no difference)
set tcp.meter [282 8 12 83 2 0 1 1] + TB_right [0 0 0 0 1 0 1 1]
set tcp.meter.vu.div [1]
set tcp.meter.readout.color [0 0 0 0]
