NAME

Lab::Moose::Instrument::Lakeshore340 - Lakeshore Model 340 Temperature Controller

VERSION

version 3.701

SYNOPSIS

 use Lab::Moose;

 # Constructor
 my $lakeshore = instrument(
     type => 'Lakeshore340',
     connection_type => 'LinuxGPIB',
     connection_options => {pad => 22},
     
     input_channel => 'B', # set default input channel for all method calls
 );

 my $temp_B = $lakeshore->get_T(); # Get temp for input 'B' set as default in constructor.

 my $temp_A = $lakeshore->get_T(channel => 'A'); # Get temp for input 'A'.

METHODS

get_T

my $temp = $lakeshore->get_T(channel => $channel);

$channel can be 'A' or 'B'. The default can be set in the constructor.

get_value

alias for get_T.

get_sensor_units_reading

 my $reading = $lakeshore->get_sensor_units_reading(channel => $channel);

Get sensor units reading (like resistance) of an input channel.

set_setpoint/get_setpoint # set/get SP for loop 1 in whatever units the setpoint is using $lakeshore->set_setpoint(value => 10, loop => 1); my $setpoint1 = $lakeshore->get_setpoint(loop => 1);

set_T

alias for set_setpoint

set_heater_range/get_heater_range

 $lakeshore->set_heater_range(value => 1);
 my $range = $lakeshore->get_heater_range();

Value is one of 0 (OFF),1,...,5 (MAX)

set_control_mode/get_control_mode

Specifies the control mode. Valid entries: 1 = Manual PID, 2 = Zone, 3 = Open Loop 4 = AutoTune PID, 5 = AutoTune PI, 6 = AutoTune P.

 # Set loop 1 to manual PID
 $lakeshore->set_control_mode(value => 1, loop => 1);
 my $cmode = $lakeshore->get_control_mode(loop => 1);

set_control_parameters/get_control_parameters

 $lakeshore->set_control_parameters(
    loop => 1,
    input => 'A',
    units => 1, # 1 = Kelvin, 2 = Celsius, 3 = sensor units
    state => 1, # 0 = off, 1 = on
    powerup_enable => 1, # 0 = off, 1 = on, optional with default = off
 );
 my %args = $lakeshore->get_control_parameters(loop => 1);

set_input_curve/get_input_curve

 # Set channel 'B' to use curve 25
 $lakeshore->set_input_curve(channel => 'B', value => 25);
 my $curve = $lakeshore->get_input_curve(channel => 'B');

set_remote_mode/get_remote_mode

 $lakeshore->set_remote_mode(value => 1);
 my $mode = $lakeshore->get_remote_mode();

Valid entries: 1 = local, 2 = remote, 3 = remote with local lockout.

set_pid/get_pid

 $lakeshore->set_pid(loop => 1, P => 1, I => 50, D => 50)
 my %PID = $lakeshore->get_pid(loop => 1);
 # %PID = (P => $P, I => $I, D => $D);

set_zone/get_zone

 $lakeshore->set_zone(
     loop => 1,
     zone => 1,
     top  => 10,
     P    => 25,
     I    => 10,
     D    => 20,
     range => 1
 );

 my %zone = $lakeshore->get_zone(loop => 1, zone => 1);
