Kt34400FResistance¶

Access interface members using: driver.f_resistance

Where driver is a reference to the driver’s root interface returned by the constructor.

class Kt34400FResistance¶

Kt34400FResistance interface.

property aperture¶

Specifies the integration time in seconds (called aperture time) for 4-wire resistance measurements.

Access:: ReadWrite
Type:: datetime.timedelta

property aperture_enabled¶

Enables the setting of integration time (called aperture time) for 4-wire resistance measurements.

Access:: ReadWrite
Type:: bool

property auto_range¶

Disables or enables autoranging for 4-wire resistance measurements.

Access:: ReadWrite
Type:: AutoZero
Remarks:: Autoranging goes down a range at less than 10% of range and up a range at greater than 120% of range.
When this property is set to Ag3446xAutoRangeOn, instrument selects the range based on the input signal.
Selecting a fixed range with Range property disables AutoRange property to Ag3446xAutoRangeOff.
Querying this property when set to Ag3446xAutoRangeOnce, returns Ag3446xAutoRangeOff but it never returns Ag3446xAutoRangeOnce.
Default value is Ag3446xAutoRangeOn.

property auto_range_enabled¶

Enables or disables auto ranging for 4-wire resistance measurements.

Access:: ReadWrite
Type:: bool

configure(*args, **kwargs)¶

Overloaded function.

configure(self: keysight_kt34400.keysight_kt34400.Kt34400FResistance, range: float, resolution: keysight_kt34400.keysight_kt34400.Resolution) -> None
Configures the meter for 4-wire resistance measurements. Minimum Range is 100 ohms.
Parameters:
range (float) - Desired range in Ohms. Valid values are from 1 kOhm to 100MOhm. Positive values only.

resolution (Resolution) - Measurement resolution. Select from Least (4.5 digits), Default (5.5 digits) and Best (5.5 digits). Higher resolutions (5.5 digits) result in slower measurement speeds.
Returns:

None

remarks:

This method resets all resistance measurement parameters and trigger parameters to their default values. Then, it configures the meter for 4-wire resistance measurements but does not initiate the measurement.

Desired range is 100 Ω(MIN), 1 kΩ, 10 kΩ, 100 kΩ, 1 MΩ, 10 MΩ, 100 MΩ(MAX) or Auto range(AUTO).

Instrument can automatically select the measurement range using Kt34400.range.

If input value is greater than that can be measured on the selected range , "+9.9E+37" is returned.
