Summary of change:
Connect '''pump(-)''' and '''nernst''' with 100Ohm, connect '''nernst''' and '''pump(+)''' with 100Ohm too. Connect a LED's anode with serial 500Ohm to 12V, cathode to Heater(-). *First Measure the voltage between the GND and Pump(-). It shold allround +4V (3.85 - 5.15 on older boards) *Measure the voltage between '''pump(-)''' and '''pump(+)''' (Pump(-) shold be the DVM's COM) it should between -4mv and +4mV, when wbo2 is off. If the voltage not in the specified range, set to fit, by the pump_pw_zero variable *After finished setting pump pw zero, turn on the wbo2 (mde02 in the terminal) The LED should start lighting. Switch to the display's 7th page (Terminal: mlp07). Check Ri(Top left corner), it should between 90 and E0. Change the DVM's (+) from '''pump(+)''' to '''nernst''' after a while, the voltage should rise to +450mV, if not, you can set by wbo2_nernst_dc_target variable
