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.

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 CL310 is compatible with OMEGA Pressure Modules. The
accessory PCL-PMA is required for pressure measurement.
Note: Pressure is not read from modules with frequency or pulse
train mode enabled.
Note: On high pressure modules engineering units normally
associated with low pressure ranges such as, inH
not valid selections. Selecting one of these units with a high
pressure module attached will cause the display to read "----".
To avoid a violent release of pressure in a pressurized system, shut
off the valve and slowly bleed off the pressure before you attach the
pressure module to the pressure line.
