Measurement Ranges
Scaling the Measure Value
At the analog output of the ES430.1, the following dependencies on the output
voltage apply for the measure value output:
TIP
At the analog output, lambda measure values of max. lambda=10 can be dis
-
played; in the calibration software, lambda measure values of max.
lambda=16 can be output.
