Measuring Pressure - Omega PCL1200 User Manual

3.3-2 Using Resistance-Temperature-Detectors (RTDs)
The supported types of RTDs are shown in Section 8.
Specifications. RTDs are characterized by their 0°C resistance,
R0. The calibrator accepts two, three, and four wire inputs, with
four wire input being the most accurate.
To use the RTD option, apply the following steps:

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.

3.4 Measuring Pressure

Note: The Omega Pressure Module connector 700mA needs to be
purchased to connect pressure module to calibrator.

Switch to lower display [LOWER] from Main Menu.
Select RTD from the primary parameters. Select [IN] from
input/output control.
Choose 2, 3, or 4-wire connection [2W, 3W, 4W]. (4-wire
allows for the most precise measurement)
Select RTD type from the sensor types.
Attach RTD leads as shown in Figure 8.
