dmm.fourrtd
Attribute
Indicates the type of four-wire RTD being used.
Usage
To read the 4-wire RTD type:
value = dmm.fourrtd
value
: Represents the present type for 4-wire RTD
To write the 4-wire RTD type:
dmm.fourrtd = value
value
: Represents the desired type for 4-wire RTD. Use one of the following for values:
dmm.RTD_PT100 or 0 for type PT100
dmm.RTD_D100 or 1 for type D100
dmm.RTD_F100 or 2 for type F100
dmm.RTD_PT385 or 3 for type PT385
dmm.RTD_PT3916 or 4 for type PT3916
dmm.RTD_USER or 5 for user specified type
Remarks
This attribute is only valid when dmm.func = ―temperature‖. All other configurations
generate an error and return nil when queried.
Changing functions with
dmm.func
(on page 9-91) has no effect on this setting.
The
dmm.reset
(on page 9-112) function will set this attribute to dmm.RTD_PT100.
Example
To set the type of four-wire RTD for PT3916:
dmm.func = "temperature"
dmm.fourrtd = dmm.RTD_PT3916
