3.2.7 Example procedure: Measure or simulate an RTD (or Resistance)
These examples (A and B) show Channel 1 (CH1) set-up to
measure or simulate an RTD. A 4-Wire configuration gives the
best accuracy; a 2-Wire configuration has the lowest accuracy
(4-Wire RTD shown).
Note: To measure or simulate resistance (
Ω), set the
Resistance function.
Example A 1. Set the applicable software options; see Section 3.2.1
(Procedure overview).
2. Complete the electrical connections.
3. If necessary change the Settings and continue with the
measure operation.
Values to set:
RTD Type (Set the applicable RTD); see Tabl e A1 (front
cover) for the available options.
Example B 1. Set the applicable software options; see Section 3.2.1
(Procedure overview).
2. Complete the electrical connections.
