NAME

Lab::Instrument::ILM - Oxford Instruments ILM Intelligent level meter

SYNOPSIS

    use Lab::Instrument::ILM;
    
    my $ilm=new Lab::Instrument::ILM($isobus,3);
    print $ilm->get_level();

DESCRIPTION

The Lab::Instrument::ILM class implements an interface to the Oxford Instruments ILM helium level meter (tested with the ILM210).

CONSTRUCTOR

    my $ilm=new Lab::Instrument::ILM($isobus,$addr);

Instantiates a new ILM object, for example attached to the IsoBus device (of type Lab::Instrument::IsoBus) $IsoBus, with IsoBus address $addr. All constructor forms of Lab::Instrument are available.

METHODS

get_level

    $perc=$ilm->get_level();
    $perc=$ilm->get_level(1);

Reads out the current helium level in percent. Note that this command does NOT trigger a measurement, but only reads out the last value measured by the ILM. This means that in slow mode values may remain constant for several minutes.

As optional parameter a channel number can be provided. This defaults to 1.

CAVEATS/BUGS

probably many
