__init__()

Initialize the Keithley 2000 multimeter.

Usage

Source

__init__(
    interface,
    **kwargs,
)

Parameters

interface: str

VISA resource name or interface identifier.

**kwargs: dict

configure2WireOhm()

Configure the Keithley 2000 to detect 2-wire resistance.

Usage

Source

configure2WireOhm(
    digits=None,
    count=None,
    window=None,
    NPLC=None,
    dFil=None,
    resistance_range=None,
    rangeAuto=None,
    trigBus=None,
    repeatingFilter=None,
    reset=False,
)

Parameters

digits: int = None

Number of digits to display (4-8).

count: int = None

Filter count for the digital filter.

window: float = None

Filter window for the digital filter.

NPLC: int = None

Number of power line cycles to integrate over.

dFil: bool = None

If True, turn on the digital filter. If False, window and filter count are ignored.

resistance_range: float = None

Range of the resistance detection. Selected by the instrument to include the value.

rangeAuto: bool = None

Automatic detection of the measurement range. Takes additional time during measurements.

trigBus: bool = None

Sets trigger source to BUS if True.

repeatingFilter: bool = None

If True set the filter to repeating, if False to moving.

reset: bool = False
If True, the device is reset prior to configuration. Defaults to False.

configure4WireOhm()

Configure the Keithley 2000 to detect 4-wire resistance.

Usage

Source

configure4WireOhm(
    digits=None,

Filter count for the digital filter.

window: float = None

Filter window for the digital filter.

NPLC: int = None

Number of power line cycles to integrate over.

dFil: bool = None

If True, turn on the digital filter. If False, window and filter count are ignored.

resistance_range: float = None

Range of the resistance detection. Selected by the instrument to include the value of range.

rangeAuto: bool = None

Automatic detection of the measurement range. Takes additional time during measurements.

trigBus: bool = None

Sets trigger source to BUS if True.

repeatingFilter: bool = None

If True set the filter to repeating, if False to moving.

reset: bool = False

getFunction()

Get the current measurement function of the device.

Usage

Source

getFunction()

Returns

str
The current measurement function.

getReading()

Get the latest reading from the device.

Usage

Source

getReading()
