3. Choose 2, 3, or 4-wire connection [2W, 3W, 4W]. (4-wire allows for the most precise
measurement)
4. Select RTD type from the sensor types.
5. Attach RTD leads as shown in Figure 8.
Figure 8. Measuring Temperature with RTD Connection
Resistance can also be measured using this function. To do so, use the above procedure
and choose OHMS from the sensor types. This option can be used along with a table to
measure an RTD which is not programmed into the calibrator.
4. Using Source Modes
The calibrator can generate calibrated signals for testing and calibrating process instruments.
It can source resistances and the electrical output of RTD and thermocouple temperature
sensors.
4.1 Setting 0% and 100% Output Parameters
To set the 0% and 100% points, use the following steps:
1. Select the [CONFIG] option from the main menu, and choose the desired primary
parameter.
2. Select output [OUT] from the input/output control, and enter the desired value. For
example select [RTD OUT].
3. Enter 0°C with the keypad and press Enter.
4. Press any one of the four cursor control arrows to display the setpoint control menu.
5. Hold down the Function Key that corresponds to 0% [F1]. 0% will flash and the setpoint is
stored.
6. Repeat these steps, entering 100°C and holding the Function Key that corresponds to
100% [F3].
7. Use the [F2] key to step in either 25% or 10% increments.
