You can change the humidity parameter that
is output on the RH channel of HMD65 with the DIP switches on the component board. Select
the parameter you want the transmitter to output by sliding the parameter's DIP switch to
the right (ON). In the example in Figure 1, the selected output parameter is dew point/frost point temperature
(Tdf). Keep the other DIP switches in the OFF position
(left).
The selected parameter uses the default
scaling shown in Table 1.
Table 1. HMD65 Default Parameter
Scaling
Parameter
Default Scaling for 0 … 10 V Output Range
RH
0 … 100 %RH
Td
-40 ... +80 °C (-40 ... +176 °F)
Tdf
-40 ... +80 °C (-40 ... +176 °F)
A
0 … 300 g/m3 (0 … 131.1 gr/ft3)
X
0 … 600 g/kg (0 … 4200 gr/lb)
Tw
-40 ... +80 °C (-40 ... +176 °F)
H
-40 … 1600 kJ/kg (-9.5 ... 695.6 Btu/lb)
CAUTION Note that the humidity
output parameter selected with the DIP switches on the transmitter component board will be
used instead of the parameter selected with Insight. When using Insight to configure the
output, set all humidity parameter selection DIP switches on the transmitter component
board to the OFF position (left) to ensure they do not cause a
conflict with the Insight settings.
If you use Insight to set both analog output channels to output T measurement, the humidity
parameter DIP switches do not have an effect on the output.
