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:
1.
Switch to lower display [LOWER] from Main Menu.
2.
Select RTD from the primary parameters. Select [IN] from
input/output control.
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.
3.4 Measuring Pressure
Note: The DMC1410 is compatible with BETA Calibrator Pressure
Modules. The accessory BPPA-100 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
2
O, cmH
2
O, etc. are
not valid selections. Selecting one of these units with a high
pressure module attached will cause the display to read "----".
Warning!
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.
