If you are using SPRTD(Standard Platinum RTD), select SPRTD and specify the seven
coefficients under SPRTD submenu.
The ITS (International Temperature Scale) -90 standard provides two reference
equations for Standard Platinum Thermometers covering temperature range from
18.8033K to 1234.93K. However, one SPRTD usually cannot cover the entire range,
so the temperature range is broken up into a few subranges. These subranges depend
on the calibration point of temperature scale and are based on the melting or triple
points of various pure substances. For an exact list of the elements needed and details
on RTD calibration, refer to NIST Technical Note 1265 “Guidelines For Realizing the
International Temperature Scale of 1990”. In each subrange, the calibration constants
required for that subrange are listed.
Default
The default sensor type in DL-1060 is PT100.
How to set up RTD
You can set up the RTD configuration either through the front panel operation or
through the remote interface operation as shown in
Figure 3-10
or through the
remote interface operation.
