Keysight 34461A Truevolt DMM.

Methods

close

Close the underlying transport.

measure_ac_current

Trigger an AC-current measurement and return the value (amperes RMS, vendor-dependent).

measure_ac_voltage

Trigger an AC-voltage measurement and return the value (volts RMS, vendor-dependent).

measure_dc_current

Trigger a DC-current measurement and return the value (amperes).

measure_dc_voltage

Trigger a DC-voltage measurement and return the value (volts).

measure_four_wire_resistance

Trigger a 4-wire-resistance measurement and return the value (ohms).

measure_resistance

Trigger a 2-wire-resistance measurement and return the value (ohms).

open

Open transport and clear status/error queue.

set_ac_current_nplc

Unsupported — AC functions integrate via filter bandwidth (CURR:AC:BAND), not NPLC.

set_ac_current_range

Set manual AC-current range to value amperes; None selects auto-range.

set_ac_voltage_nplc

Unsupported — AC functions integrate via filter bandwidth (VOLT:AC:BAND), not NPLC.

set_ac_voltage_range

Set manual AC-voltage range to value volts; None selects auto-range.

set_aperture_seconds

Set integration time directly in seconds.

set_dc_current_nplc

Set DC-current integration time to nplc power-line cycles.

set_dc_current_range

Set manual DC-current range to value amperes; None selects auto-range.

set_dc_voltage_nplc

Set DC-voltage integration time to nplc power-line cycles.

set_dc_voltage_range

Set manual DC-voltage range to value volts; None selects auto-range.

set_digits

Unsupported — Truevolt SCPI has no digits command; use set_aperture_nplc for resolution.

set_four_wire_resistance_nplc

Set 4-wire-resistance integration time to nplc power-line cycles.

set_four_wire_resistance_range

Set manual 4-wire-resistance range to value ohms; None selects auto-range.

set_measurement_function

Select the function with FUNC; per-function range/NPLC settings are retained across switches.

set_two_wire_resistance_nplc

Set 2-wire-resistance integration time to nplc power-line cycles.

set_two_wire_resistance_range

Set manual 2-wire-resistance range to value ohms; None selects auto-range.
