Lab::Instrument::HP34401A - HP/Agilent 34401A digital multimeter
use Lab::Instrument::HP34401A; my $Agi = new Lab::Instrument::HP34401A({ connection => new Lab::Connection::GPIB( gpib_board => 0, gpib_address => 14, ), }
The Lab::Instrument::HP34401A class implements an interface to the 34401A digital multimeter by Agilent (formerly HP). This module can also be used to address the newer 34410A and 34411A multimeters, but doesn't include new functions. Use the Lab::Instrument::HP34411A class for full functionality (not ported yet).
my $Agi=new(\%options);
$hp->autozero($setting);
$setting can be 1/'ON', 0/'OFF' or 'ONCE'.
When set to "ON", the device takes a zero reading after every measurement. "ONCE" perform one zero reading and disables the automatic zero reading. "OFF" does... you get it.
$hp->configure_voltage_dc($range, $integration_time);
Configures all the details of the device's DC voltage measurement function.
$range is a positive numeric value (the largest expected value to be measured) or one of 'MIN', 'MAX', 'AUTO'. It specifies the largest value to be measured. You can set any value, but the HP/Agilent 34401A effectively uses one of the values 0.1, 1, 10, 100 and 1000V.
$integration_time is the integration time in seconds. This implicitly sets the provided resolution.
$hp->pl_freq($new_freq); $npl_freq = $hp->pl_freq();
Get/set the power line frequency at your location (50 Hz for most countries, which is the default). This is the basis of the integration time setting (which is internally specified as a count of power line cycles, or PLCs). The integration time will be set incorrectly if this parameter is set incorrectly.
$Agi->display_text($text); print $Agi->display_text();
Display a message on the front panel. The multimeter will display up to 12 characters in a message; any additional characters are truncated. Without parameter the displayed message is returned. Inherited from Lab::Instrument::Multimeter
$Agi->display_on();
Turn the front-panel display on. Inherited from Lab::Instrument::Multimeter
$Agi->display_off();
Turn the front-panel display off. Inherited from Lab::Instrument::Multimeter
$Agi->display_clear();
Clear the message displayed on the front panel. Inherited from Lab::Instrument::Multimeter
$id=$Agi->id();
Returns the instrument ID string. Inherited from Lab::Instrument::Multimeter
Inherited from Lab::Instrument::Multimeter
$resistance=$Agi->get_resistance($range,$resolution);
Preset and measure resistance with specified range and resolution.
$datum=$Agi->get_voltage_dc($range,$resolution);
Preset and make a dc voltage measurement with the specified range and resolution.
Range is given in terms of volts and can be [0.1|1|10|100|1000|MIN|MAX|DEF]. DEF is default.
[0.1|1|10|100|1000|MIN|MAX|DEF]
DEF
Resolution is given in terms of $range or [MIN|MAX|DEF]. $resolution=0.0001 means 4 1/2 digits for example. The best resolution is 100nV: $range=0.1; $resolution=0.000001.
$range
[MIN|MAX|DEF]
$resolution=0.0001
$range=0.1
$resolution=0.000001
$datum=$Agi->get_voltage_ac($range,$resolution);
Preset and make an ac voltage measurement with the specified range and resolution. For ac measurements, resolution is actually fixed at 6 1/2 digits. The resolution parameter only affects the front-panel display.
$datum=$Agi->get_current_dc($range,$resolution);
Preset and make a dc current measurement with the specified range and resolution.
$datum=$Agi->get_current_ac($range,$resolution);
Preset and make an ac current measurement with the specified range and resolution. For ac measurements, resolution is actually fixed at 6 1/2 digits. The resolution parameter only affects the front-panel display.
$inttime=$Agi->config_voltage($digits,$range,$count);
Configures device for measurement with specified number of digits (4 to 6), voltage range and number of data points. Afterwards, data can be taken by triggering the multimeter, resulting in faster measurements than using read_voltage_xx. Returns string with integration time resulting from number of digits.
@array = $Agi->get_with_trigger_voltage_dc()
Take data points as configured with config_voltage(). returns an array.
$Agi->scroll_message($message);
Scrolls the message $message on the display of the HP.
$message
$Agi->beep();
Issue a single beep immediately.
($err_num,$err_msg)=$Agi->get_error();
Query the multimeter's error queue. Up to 20 errors can be stored in the queue. Errors are retrieved in first-in-first out (FIFO) order.
$Agi->reset();
Reset the multimeter to its power-on configuration.
