Lp02 pyranometer 1. Introduction the lp02 is an iso-second-class pyranometer that monitors solar radiation for the full solar spectrum range. It produces a millivolt signal that can be measured directly by a campbell scientific datalogger. The lp02 can provide solar radiation measurements for many m...
Lp02 pyranometer 4. Quickstart please review section 7, operation, for wiring, crbasic programming, and edlog programming. 4.1 siting considerations the lp02 is usually installed horizontally, but can also be installed at any angle including an inverted position. In all cases, it will measure the fl...

The leveling screws should lightly touch the mounting plate (see figure 4-5). Figure 4-5. Lp02 pyranometer attached to cm225 solar sensor mounting stand 4. Starting...
Lp02 pyranometer 5. Tighten the mounting screws to secure the assembly in its final position. 6. Route the sensor cable to the instrument enclosure. 7. Use cable ties to secure the cable to cm225 bracket and to the vertical pipe or crossarm and tripod/tower (see figure 4-5). 4.3 use scwin to program...
Lp02 pyranometer 3. Select lp02 pyranometer, and select the right arrow (in center of screen) to add it to the list of sensors to be measured, and then select next. 4. Enter the sensitivity supplied on the manufacturer’s certificate of calibration; this sensitivity is unique to each sensor. The publ...

In the confirm window, click yes to download the program to the datalogger. 8. Click on wiring diagram and wire according to the wiring diagram generated by sho...
Lp02 pyranometer 5. Overview the lp02 pyranometer is designed for continuous outdoor use. Due to its flat spectral sensitivity from 280 to 3000 nm, it can be used in natural sunlight, under plant canopies, in green houses or buildings, and inverted to measure reflected solar radiation. Two lp02s can...
