VERSION

version 3.920

SYNOPSIS


            

              
              
use Lab::Moose;
# Constructor
my $lakeshore = instrument(
    type => 'Lakeshore372',
    connection_type => 'Socket',
    connection_options => {host => '192.168.3.24'},
     
    input_channel => '5', # set default input channel for all method calls
);
my $temp_5 = $lakeshore->get_T(channel => 5); # Get temperature for channel 5.
my $resistance_5 = TODO

Example: Configure inputs


            

              
              
# enable channels 1..3
for my $channel (1..3) {

       channel => $channel,
       enabled => 1,
       dwell => 1,
       pause => 3,
       curve_number => 0, # no curve
       tempco => 1, # negative temp coeff
   );
}
# disable the other channels
for my $channel ('A', 4..16) {
     $lakeshore->set_inset(
