VERSION

version 3.900

SYNOPSIS

use Lab::Moose;

# Constructor
my $lakeshore = instrument(
    type => 'Lakeshore372',
    connection_type => 'VISA::GPIB',
    connection_options => {pad => 10},
    input_channel => 'A', # set default input channel for all method calls
);


my $temp_B = $lakeshore->get_T(channel => 'B'); # Get temperature for channel 'B'
my $resistance_B = $lakeshore->get_sensor_units_reading(channel => 'B'); # Get resistance for channel 'B'

 
# setup input channel 'A' for fixed 100kOhm range with 10nA excitation
$lakeshore->set_intype(
    channel => 'A',
    sensor_type => 3, # NTC RTD
    autorange => 0,
    range => 8, # 100kOhm
    compensation => 1, # current reversal for EMF compensation
    units => 1, # use Kelvin for setpoint control
    sensor_excitation => 0, # 1mV =>  10nA excitation current
 );

METHODS
