Documentation:
    DESCRIPTION
    This macro set provides the possibility to read electrometers with automatic gain adujustement. %PRE% Three types of electrometers are supported for the moment:
    • Type 0: ADC reading with three input lines with all bit combinations for gain adjustment. Eight posible gain values are posible.
    • Type 1: ADC reading with three input lines with exclusive values. Only three gain values are posible.
    • Type 2: Other type. The macros do not read the counter value but other macros or SPEC itself take care of that. The min/max thresholds are normalized with counting time. For the moment, in this case only three mutually exclusive input lines are used for gain adjustment. Electrometers are seen in SPEC as counters and must be defined as such in SPEC config.
    • Type 3: ID11 electrometers. Like type 1 only that the gains can vary in elmeteradd you need to supply ( not the min gain ) but the gains for the three relay positions.
    • Type 4: Like type 3 but with a vmeadc linux device server madc
    • Type 5: Novelec on a WAGO box. First trial 25.1.2005
    • Type 6: Novelec on a WAGO box. Value is read with icv150 (petitdem).
    • Type 7: gain + adc control by wago (petitdem).



      SETUP
      Use the setup command:
    • Start electrometer definition with a line containing elmeterinit Use elmeteradd to configure a new electrometer.
    • To setup several electrometers, use elmeteradd several times. Without parameters elmeteradd allows keyboard entry for setup.
