try to connect PC GND and LV GND, PC GND and HV GND, but the problem did not resolved.

9:00 maybe the promble was due to Single Chip Card?

(1) module connect with only HV -> stable, 10(?)nA@-80V

(2) module connect with HV and DiplayPort -> unstable:often drop to 0 A

(3) module connect with HV and DisplayPort and LV power supply (ON) -> unstable

(4) module connect with HV and DisplayPort and LV (ON). LV GND and YARR GND short -> unstable

(5) module connect with HV and DisplayPort and LV (ON). HV GND and YARR GND short -> stable 20nA@-80V

jumper connecter whom name HV and GND added which (maybe) select short with HV and sensor, HV and LV. short sensor GND - HV GND - LV GND, and short YARR - LV GND.

--> stable current !!

re-setup

##run plan##

(1) full depletion voltage is different with vendor and ITk.

(2) tune different way:

1.target threshold:1500, include ToT tuning

2.target threshold:1500, NOT including ToT tuning for disappearing living analog core pattern.

3. target threshold:1000, ???
