Accupar lp-80 manual

3 DEFINITIONS AccuPAR LP Definitions The AccuPAR LP uses several variables to calculate Leaf Area Index, and displays values for these variables on the screen as mea- surements are taken. This chapter will discuss these variables and their definitions. Each LP light bar should come with the following: AccuPAR model LP light bar - RS Cable (for data transfer) - Operator’s manual - External PAR sensor attached to a 25 ft cable with 3 pin lock - LP utility software (for data transfer) You will also need: . AccuPAR LP 1 INTRODUCTION 1 Introduction Welcome to Decagon’s AccuPAR model LP PAR/LAI Ceptome-ter. The AccuPAR measures Photosynthetically Active Radiation (PAR) and can invert these readings to give Leaf Area Index (LAI) for your plant canopy. This manual is .

Leaf area index (LAI) (based on Photosynthetically Active Radiation (PAR) measurements) at the two ICP-IM intensive plots (station codes and ) at the 90 ha study site LTER Zöbelboden, Austria. 2 ABOUT THE LP AccuPAR LP ON/OFF Key: Located in the upper left corner, it turns the in-strument on or o. The AccuPAR turns itself o automatically after 10 minutes of inactivity. MENU Key: Cycles between the four menus. UP and DOWN ARROW KEYS: In PAR Sampling menu, they initiate above (up arrow) and below (down arrow) canopy PAR readings.

The LP’s simplicity of use has a lot to do with its automation. Rather than the painstaking 4- to 5-hour destructive method of running leaves through a conveyor belt, the LP instead measures the photosynthetically active radiation that is impinging on the measurement wand. accupar lp Measuring canopy density can be problematic There are several methods to measure how much light is intercepted by a canopy in order to determine if water loss is from evaporation or transpiration. AccuPAR LP Appendix B: Troubleshooting 79 Appendix B: Troubleshooting The AccuPAR LP is a high performance, low maintenance instrument, designed to have few problems if used with care. Unfortunately, sometimes even the best operators using the best instruments encounter technical difficulties.
