16-bit D/A resolution for Out1 allows
0.1 resolution with a span of more
than 200 units.
1)
Any of the 3 analog outputs of the HygroFlex 3 can be set to correspond to humidity [probe
1 or 2] or temperature [probe 1 or 2] or calculated parameter [probe 1 or 2] or user defined
calculation or optional analog probe signal (such as pressure). The HygroFlex is set at the
factory as specified when ordering. These settings can be changed at any time with the
optional HW4 software.
2)
The output signals are set at the factory according to the type and range specified when ordering. A
label located on the transmitter housing shows the type of output signal for each unit.
The analog output signals are linear and are consistent with the requirements of most data/signal
processing instrumentation (panel meter, controller, computer card, etc.).
2.4 Optional display and keypad
The LC display shows which probe input is being displayed (small indicator on top of the display)
and up to 2 parameters measured by the probe, with the associated engineering unit. When
relevant, the message line provides additional information.
