PT200xHM measurement function, no voltage

[Fast]

With OA feature, I can not setup for voltage setting.

I write to:

1AAh = 426d
b6=oa1_g1 b5-3= oa_sel1 b2-1=oa1_gain b0=oa1_en
0000 000 0001 0001 0x0011
'000': output from current measurement block 1
'001': output from current measurement block 3
'010': OA_Meas1: output from measurement function, unprocessed signal
'011': OA_Meas2: output from measurement function, low-pass + high-pass filtering
'100': OA_Meas3: output from measurement function, LP + two times HP filtering
'101': 2.5 Volt
'110': OA_Meas4: output from measurement function, low-pass filtering

meas_func1 register (1ACh)
reserved b12-9= dac_fb_sel b8=cur_volt0, b7-5 =d_ls_sel b4-2=s_hs_sel b1-0 oa_cur
000 0000 0 001/.010 0.01 00 = 0044h HS2 - LS1

meas_func2 register (1ADh)
b15=offset_hp2_sel, b14=offset_hp1_sel, b13-10=fc_hp2_sel, b9-7=gain_hp1_sel b6-3=fcut_hp1_sel b2-1=volt_att
xxxx xxxx xxxx x000=0 Unfiltered div by 30

Scope shows flat line at 0V

Yes it has M in part name.

What have I missed?

Yes it does work. Nice rest over weekend.
