IPS sniffer at MC and a few other actions on environmental probes
We moved the 50Hz sniffer from CB UPS (Pr_power50) to the IPS of MC building (new channel name is Em_IPSMC_50Hz). This is needed temporary to investigate the noise on the IPS produced by the switching of the SCR controller of the MC air conditioner heating.
We also:
- reduced by 3.16 the amplification of MC microphone wich was a bit saturating,
- removed from DAQ the two unused channels Em_MABDMC01 and 03
which are not connected to any magnetometer (there is only one magnetometer in MC which is channel Em_MABDCE02),
- reconnected channel Em_AC_EIB to the microphone on EIB, and removed the microphone from EE room,
- verified that the two seismometers in EE room (Em_SEdiodeBOX and floorEE) are out of battery power.
