4.7 Analog signal configuration (HygroFlex 1 and 3 main PCB)
On the HygroFlex 1 and HygroFlex 3, the type of analog output signal can be selected by means
of jumpers on the PCB:
HygroFlex 1: to configure the temperature range
and unit, use this 3-pin service connector and
connect to a PC with cable # AC1623.
HygroFlex 3: the transmitter can be configured
by connecting the RS232 / RS485 output to a
PC.
For both transmitters, configuration requires the
HW4 software installed on the PC.
