Section 3 – Electrical Connection and Temperature Measuring
Range Selection
All electrical connections and wiring should be performed by a
suitably trained professional only.
3.1 Electrical Connection
Follow the electrical connection diagram shown in figure 3-1 below to set up
your Temperature/Relative Humidity Transmitter.
Figure 3-1 Electrical Connection Diagram
3.2 Temperature Measuring Range Selection:
The temperature measuring range of the HX93B can be modified by making
a minor change to a connector J4. The standard temperature measuring range
is -30 to 75°C (-22 to 167°F) without adding any jumper on connector J4. If
you would like to change the range to -20 to 75°C (-4 to 167°F), add a jumper
on connector J4 pin 1 to pin 2. See the diagram below for the location of the
connector and its pins.
