8 Troubleshooting
Any problem with the SRS will most likely manifest as failed com-
munication or erroneous readings. Before contacting Decagon about
the sensor, please check these troubleshooting steps.
8.1

Data Logger

1. Check to make sure the connections to the data logger are both
correct and secure.
2. Ensure that your data logger batteries are not dead or loose.
3. Check the configuration of your data logger in ECH
or DataTrac 3 to make sure you have selected the correct SRS
version (NDVI or PRI).
4. If using Decagon loggers make sure that you are using the cor-
rect versions of logger firmware and software.
8.2 Sensors
1. Ensure that you install the sensors according to the "Installa-
tion" section of this manual.
2. Check sensor cables for nicks or cuts that could cause a mal-
function.
8.3 Calibration
Decagon Devices Inc. factory calibrates the Spectral Reflectance Sen-
sor against a NIST traceable light source. Details about your sensor
calibration are available upon request. We have a recalibration ser-
vice available and recommend that you send in your SRS sensors for
recalibration every one to two years. You will need a Return Material
Authorization (RMA) form to send your sensor in for recalibration.
Call or email Decagon at 509-332-5600 or support@decagon.com to
arrange for a RMA, or to obtain your sensor calibration information.
