If this problem occurs:
Refer to:
Sensor not responding
Problem #1
Sensor reading too low
Problem #2
Sensor reading too high
Problem #3
1. PROBLEM:
Sensor not responding.
SOLUTION:
Check power to the sensor
Check sensor cable and 3.5 mm plug integrity
Check data logger wiring to ensure White is 12 V supply, Red is
digital out, and Bare is ground.
2. PROBLEM:
Sensor reading too low.
SOLUTION
Check for air gaps around sensor needles. These could be produced
below the surface of the substrate when the needle contacts a
large piece of material and pushes them out of the way.
Ensure the calibration equation you are using is appropriate for your
media type. There are significant differences between substrate
calibrations so be sure to use the one specific to your substrate.
3. PROBLEM:
Sensor reading are too high.
