L'humidite est a 45 %, run 738779 avec Vth > 487 la plupart du temps
Les HV sont a 6900
>>> hv.status(0) Polarity: - Status: 00001 Vset: 6900.0 Iset: 0005.00 Vmon: 6899.2 Imon: 0000.45 RampUp: 005 RampDown: 050 >>> hv.status(1) Polarity: - Status: 00001 Vset: 6900.0 Iset: 0005.00 Vmon: 6899.0 Imon: 0000.40 RampUp: 005 RampDown: 050
A 7000 V le courant est de 0.5 micro par chambre
la HV eff est de l'ordre de 6900 V (P ~ 1000 hPa, T ~ 23 C)

| 738781 | 7000 | 6858 | 2132 | 764 | 482 | 35.83 | 1.04 | 22.61 | 0.91 | 0.02 | 1.277 |

P ( 0 m) = 1037 hPa
P( Villeurbanne 170 m) = 1016 mbar
⇒ HV eff = 6858 V
Donc equivalent a 6600 au CERN
