How can ETo be calculated using an NR-LITE2-L?

The net radiation measurement must be scaled to give total megajoules per square meter (MJ/m2) received during the period between calling the output table with the ETsz() instruction in it. (This is normally the scan interval.) If the sensor is scaled to output flux, the value needs to be converted to megajoules. For example, if the output flux unit is W/m2, multiply the flux value by the scan interval (in seconds) and by 10-6 to convert the value to megajoules (that is, MJ = W x scan x 10-6).
