For CE compliance a properly grounded shielding cable is required.
1) Unscrew the strain relief and route the cable(s). Use the strain
relief on the le for power in and signal out (Tout/vout) and the
strain relief on the right for relay.
2) Connect the wires as shown in gure 2a and 2b.
3) Tighten the strain relief.
1) Select the desired measurement range (see step 3).
2) Select the desired measurement mode (see step 4).
3) Congure the relay (oponal) (see step 5).
The device is now ready to be used.
Congure the outputs:
• Temperature output (Tout)
• Velocity output (vout)
Select the output mode, current (mA) or voltage (V), by installing
jumpers as shown in Figure 4. Both outputs, temperature (T)
and velocity (v), are congured separately.

minimum straight duct approach
Round ducts:
D = duct diameter
Rectangular ducts:
If there is a horizontal curve or change in the duct size,
D = width of the duct
If there is a vercal curve or change in the duct size,
D = height of the duct
