Description
Analog Output Scaling
Allows the user to select the full-scale PPM value
that represents maximum analog output (e.g., 20
mA) for scaling the analog output. Adjustment range
is from 100 PPM to 3500 PPM. Default = 3500
PPM. (The setting cannot be adjusted above 3500.)
Use the Up and DOWN buttons to set the desired
full scale value. All outputs will be scaled to the
indicated full scale value.
NOTE:
Alarm values are not scaled, but are
absolute values. Setting a smaller full scale does
not correspondingly scale the alarm setting.
NOTE:
When the ppm level is greater than the
programmed analog output Full Scale ppm (P.-16),
the analog output will go to a 10% over range state
(indicating that the concentration is too high for the
analog output to achieve). For example, for a 1-5 V
setting the analog output would go to 5.5 V, for
4-20 mA it would go to 22 mA and so on.
NOTE:
The analog output signal range is from 100 ppm to
the default value of 3500 ppm, which is scaled across the
actual output range selected by the analog output type
parameter P.-03. The upper PPM limit is programmable using
analog output scaling parameter P.-16. This parameter sets
the full scale PPM value creating a PPM range across which
the analog output is scaled. See Figure 15 for more details.
