9.1 Example Programs using Single-Ended Measurement
Instructions
The example programs for the CR1000 and CR10X use the SW12V terminal to
switch power to the probe, delay for 3 seconds and measure the output voltages
using single-ended measurement instructions.
Relative humidity and temperature (deg C) are measured on single-ended input
channels 1 and 2 respectively. The program sets relative humidity = 100 if the
measured value is > 100 but less than 103%. Values > 103% are not set = 100,
and indicate a problem with the sensor or its calibration.
