Lab::Instrument::HP34401A Description

Lab::Instrument::HP34401A is a HP/Agilent 34401A digital multimeter. Lab::Instrument::HP34401A is a HP/Agilent 34401A digital multimeter.SYNOPSIS use Lab::Instrument::HP34401A; my $hp=new Lab::Instrument::HP34401A(0,22); print $hp->read_voltage_dc(10,0.00001);The Lab::Instrument::HP34401A class implements an interface to the 34401A digital multimeter by Agilent (formerly HP).CONSTRUCTOR my $hp=new(%options);METHODSread_voltage_dc $datum=$hp->read_voltage_dc($range,$resolution);Preset and make a dc voltage measurement with the specified range and resolution.$rangeRange is given in terms of volts and can be . DEF is default.$resolutionResolution is given in terms of $range or . $resolution=0.0001 means 4 1/2 digits for example. The best resolution is 100nV: $range=0.1; $resolution=0.000001.read_voltage_ac $datum=$hp->read_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 digits. The resolution parameter only affects the front-panel display.read_current_dc $datum=$hp->read_current_dc($range,$resolution);Preset and make a dc current measurement with the specified range and resolution.read_current_ac $datum=$hp->read_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 digits. The resolution parameter only affects the front-panel display.display_on $hp->display_on();Turn the front-panel display on.display_off $hp->display_off();Turn the front-panel display off.display_text $hp->display_text($text); print $hp->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.display_clear $hp->display_clear();Clear the message displayed on the front panel.scroll_message $hp->scroll_message($message);Scrolls the message $message on the display of the HP.beep $hp->beep();Issue a single beep immediately.get_error ($err_num,$err_msg)=$hp->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.reset $hp->reset();Reset the multimeter to its power-on configuration.id $id=$hp->id();Returns the instruments ID string. Requirements: · Perl
