dmm.threertd
Attribute
Indicates the type of three-wire RTD being used.
Usage
To read the 3-wire RTD type:
value = dmm.threertd
value
: Represents the present type for 3-wire RTD.
To write the 3-wire RTD type:
dmm.threertd = value
value
: Represents the desired type for 3-wire RTD.
Use one of the following for value:
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 three-wire RTD for PT3916:
dmm.func = "temperature"
dmm.threertd = dmm.RTD_PT3916
dmm.threshold
Attribute
Indicates the threshold range.
Usage
To read the threshold setting:
value = dmm.threshold
value
: Represents the present threshold setting.
To write the threshold setting:
dmm.threshold = value
value
: Represents the desired threshold setting. The range for continuity is from 1 to
1000
. For frequency and period, the range is from 0 to 303V.
