2.8.2.2 3-Wire RTD Measurements
How to measure temperature with 3-Wire RTD
The following
Figure 2-11
shows theory diagram of 3-Wire RTD measurement.
1.
Insert a specified adapter into the front terminals, and connect the low thermal
patch leads to the adapter.
2.
Press TEMP button.
3.
Configure sensor type as you would be with 4-wire RTD and unit by using the
CONFIG button (refer to 3.1.8
) or skip this step to use the
default settings.
4.
Observe and take readings on the display.
※
Note: When users do the 3-wire RTD measurement the input LO and sense LO
have to be connected in short condition.
