3. Select “RTD” from the RTD Type list.
4. Set the 0%, the 100% span points and the time using either the ARROW keys or the
numeric keys
5. Select the upper display and select either “Current” or “Voltage” from the Upper
Mode list.
6. Select power mode, internal or external power. (Current only)
7. Select “%Error” from the Units list.
