STEP 2: WIRING DIAGRAMS
SELECTING THE MEASUREMENT RANGE
CONTINUED
For CE compliance, a properly grounded shielding cable is required.
1) Unscrew the strain relief and route the cable.
2) Connect the wires as shown in figure 2.
3) Tighten the strain relief.
Figure 2 - Wiring diagram 4–20 mA
1) Select the desired measurement range. (see step 4)
2) Select the desired response time. (see step 5)
3) Zero the device. (see step 6)
4) Connect the pressure tubes. Connect positive pressure to
port labeled “+” and negative pressure to port “-”.
7) Close the lid. The device is now ready to be used.
STEP 3: CONFIGURATION
STEP 4: SELECTING THE MEASUREMENT RANGE
A. For R8 models
1) Find the required measurement range and determine the range
number in the header of Chart 1.
2) Install jumpers on J1, J2 and J3 in device, as shown in Chart 2.
