Precision Temperature Measurement with 4-Wire
RTD Probe

Figure 30 - Precision Temperature Measurement with 

4-Wire RTD Probe

1.

With the RTD probe and the corresponding custom coefficients,
the total system error is 0.03°C.

2.

Disconnect any test leads from external devices.

3.

Select RTD input on the primary display as described in section
4.3.  Select the user defined curve containing the custom
coefficients for the Probe.  If custom coefficients have not yet
been entered for the Probe, follow the instructions in section 4.5
to do so.

4.

Connect the probe as shown in figure 30.
