Note: the option for "Sensor make and model" is for reference
information only. This field is intended to store information
about the physical sensor to assist in record keeping for
identification of the attached sensor.

Channel 3: A89WS-PY1: Pyranometer

Configure the following options
Sensor Name: "Solar Radiation"
Input Mode: "Current 4-20mA"
Sensor Make and Model:
"A89WS-PY1 (Li-Cor LI-200SZ)"
Sensor Minimum Range: "0"
Sensor Maximum Range: "xxxx" *
Engineering Units: "W/m^2"
Note: the option for "Sensor make and model" is for reference
information only. This field is intended to store information
about the physical sensor to assist in record keeping for
identification of the attached sensor.
* Pyranometer max range calculation:
The Sensor Maximum Range setting for the pyranometer is based on the multiplier supplied on the calibration certificate for
the sensor. Locate the multiplier on the calibration certificate. If the calibration certificate is not available, use a web
browser to access the LI-COR website at
the page and enter the serial number on the Pyranometer. The multiplier is different for each pyranometer.
Using the multiplier from the calibration certificate, multiply the absolute (positive) value by 125. The result is the Sensor
Maximum Range. e.g. Maximum Range = 125 * LicorMultiplier.
Example:
LI-COR multiplier of -11.33
Maximum Range = 125 * 11.33
Maximum Range = 1416.25 w/m^2
