To perform a reset on temperature only:
dmm.func = "temperature"
dmm.reset("active")
To perform a reset on all DMM functions:
dmm.reset("all")
Indicates the user type RTD alpha value.
To read the user type RTD alpha value:
value = dmm.rtdalpha
value: Represents the present useralpha value.
To write user type RTD alpha value:
dmm.rtdalpha = value
value: Represents the desired useralpha value.
This attribute is only valid when dmm.func = "temperature". All other
configurations generate an error and return nil when queried. Errors are also
generated if the parameter value is out of range. The valid range for user alpha is 0 to
0.01.
NOTE The following attributes share common settings and apply to both 3 and 4-wire
RTDs: dmm.rtdalpha, dmm.rtdbeta, dmm.rtddelta, and dmm.rtdzero.
Therefore, when both 3 and 4-wire RTDs are set to USER type for RTD,
switching transducers between 3 and 4 will cause both to use the same
settings (for example, dmm.rtdalpha, dmm.rtdbeta). If unique settings are
desired, they must be changed, or if they are the same, use two different DMM
configurations.

The factory default and dmm.reset
dmm.rtdbeta (on page 9-113)
dmm.rtddelta (on page 9-114)
dmm.rtdzero (on page 9-115)
To set user alpha constant for RTD to 0.005:
dmm.func = "temperature"
dmm.rtdalpha = 0.005
Section 9: Instrument Control Library (ICL)
(on page 9-91) has no effect on this setting.
(on page 9-112) function value is 0.00385055.
