How to use the nidmm.visatype.ViInt32 function in nidmm

cal_type (int): Specifies the type of calibration performed (external or
                self-calibration).

                Note: The NI 4065 does not support self-calibration.

        Returns:
            temperature (float): Returns the **temperature** during the last calibration.

On the NI 4060, the **sample_interval** value is used as the settling
                time. When sample interval is set to 0, the DMM does not settle between
                measurement cycles. The NI 4065 and NI 4070/4071/4072 use the value
                specified in **sample_interval** as additional delay. The default value
                (-1) ensures that the DMM settles for a recommended time. This is the
                same as using an Immediate trigger.

                Note: This attribute is not used on the NI 4080/4081/4082 and the NI 4050.
