Kt34400Temperature¶

Access interface members using: driver.temperature

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

class Kt34400Temperature¶

Kt34400Temperature interface.

property aperture¶

Specifies the integration time in seconds (called aperture time) for temperature measurements.

Access:: ReadWrite
Type:: datetime.timedelta

property aperture_enabled¶

Enables the setting of integration time (called aperture time) for temperature measurements.

Access:: ReadWrite
Type:: bool

property auto_zero¶

Enables or disable the autozero mode for temperature measurements.

Access:: ReadWrite
Type:: bool
Remarks:: When set to AutoZero.On, the instrument internally disconnects the input signal following each measurement and takes a zero measurement. It then subtracts the zero measurement from the preceding measurement. This prevents offset voltages present on the instrument's input circuitry from affecting measurement accuracy.

When set to AutoZero.Off, the instrument uses the last measured zero measurement and subtracts it from each measurement. It takes a new zero measurement each time you change the function, range or integration time.

configure(self: keysight_kt34400.keysight_kt34400.Kt34400Temperature) → None¶

Configures the meter for thermistor temperature measurements. Type of thermistor is fixed at 5000 and resolution setting is 3.5 digits.

Returns:: None
Remarks:: This method resets all temperature measurement parameters and trigger parameters to their default values. Then, it configures the meter for temperature measurements but does not initiate the measurement.

For thermistor measurements, the instrument auto ranges to the correct range for the transducer resistance measurement.

property f_thermistor¶

Reference to the Kt34400TemperatureFThermistor interface.

Access:: Readonly
Type:: Kt34400TemperatureFThermistor

property frtd¶

Reference to the Kt34400TemperatureFRTD interface.

Access:: Readonly
Type:: Kt34400TemperatureFRTD

measure(self: keysight_kt34400.keysight_kt34400.Kt34400Temperature) → float¶

Performs a single thermistor temperature measurement using the default values for measurement and trigger parameters. Type of thermistor is fixed at 5000 and resolution setting is 3.5 digits.

Returns:: The measured value in the current IAg34450Temperature.Units.
Return type:: float
Remarks:: This method resets all temperature measurement parameters and trigger parameters to their default values. Then, it configures the meter for temperature measurements but does not initiate the measurement.

For thermistor measurements, the instrument auto ranges to the correct range for the transducer resistance measurement.

Timeout may need to be adjusted using Kt34400.io_timeout for executing this method.

property nplc¶

Sets or gets the integration time in number of power line cycles (PLC) for temperature measurements.

Access:: ReadWrite
Type:: float
Remarks:: Only integration times of 1, 10, or 100 PLC provide normal mode (line frequency noise) rejection.

Setting the integration time also sets the resolution for the measurement.

property null_enabled¶

Enables or disables the null function for temperature measurements.

Access:: ReadWrite
Type:: bool
Remarks:: When true, automatically sets the Kt34400.null_value_auto_enabled to true.

Use Kt34400.null_value to set a fixed null value.

property null_value¶

Stores a null value for temperature measurements.

Access:: ReadWrite
Type:: float
Remarks:: Specifying this property sets the Kt34400.null_value_auto_enabled to false.

This property will be enabled when Kt34400.null_enabled is set to true.

Input range is -1.0E15 to +1.0E15.

property null_value_auto_enabled¶

Enables or disables automatic null value selection for temperature measurements.

Access:: ReadWrite
Type:: bool
Remarks:: If this property is set to true, the first measurement made will be used as the null value for all subsequent measurements. Kt34400.null_value_auto_enabled is set to false.

If this property is set to false, Kt34400.null_value specifies the null value.

The instrument sets this property to true when Kt34400.null_enabled is set to true.

property rtd¶

Reference to the Kt34400TemperatureRTD interface.

Access:: Readonly
Type:: Kt34400TemperatureRTD

set_auto_zero_once(self: keysight_kt34400.keysight_kt34400.Kt34400Temperature) → None¶

The instrument takes one zero measurement and sets autozero OFF.

Returns:: None
Remarks:: The zero measurement taken is used for all subsequent measurements until the next change to the function, range or integration time.

If the specified integration time is less than 1 PLC, the zero measurement is taken at 1 PLC to optimize noise rejection in the zero measurement.

Subsequent measurements are taken at the specified fast (less than 1 PLC) integration time.

property thermistor¶

Reference to the Kt34400TemperatureThermistor interface.
