6.8 Sourcing Ohms/RTDs
To source an RTD, follow the principle of navigating through the functions described in
the guidelines in section 4.2 and proceed as follows
:
1. Select “RTD” or “Resistance” from the Lower Mode list.
2. Select the desired RTD type from the RTD Type list (only when selecting “RTD” from
the Lower Mode list).
3. Select the desired temperature unit from the Units list (only when selecting “RTD”
from the Lower Mode list).
4. Select “Out” from the Test Mode list.
5. Connect the calibrator to the instrument being tested, as shown in Figure 11.
6. Enter the temperature or the resistance using either the ARROW keys or the
numeric keys.
Note…
The ASC-400 calibrator simulates a 2-wire RTD. To connect 3- or 4-wire
transmitter, use stacked test leads, as shown in Figure 12.
