v1.0 CALIBRATION: MultispeQ LiCOR to LiCOR PAR

Overview

Description

This is only used when recalibrating the Light Box. This calibrates the red light (at 6 intensity settings) on the box itself. To work it must be preceeded by the "v1.0 CALIBRATION: LiCOR PAR (1)" and "...(2)" to work correctly.

Directions

  1. Using a LiCOR, calibrate the Light Box itself using the "v1.0 CALIBRATION: Light box to LiCOR PAR" project. Follow the directions associated with that project.
  2. Now, plug the USB-C cable into the Light Box, and make sure both MultispeQ LiCOR sensors are attached to the Box. Place the MultispeQ LiCOR 1 in the light box.
  3. Start the measurement. Enter the

Protocols

v1.0 CALIBRATION: MultispeQ PAR to LiCOR PAR (1)

Description

This is a 3 part protocol, and is designed for all 3 to be run in order in the Desktop App.

The MultispeQ measures ambient PAR (Photosynthetically Active Radiation, which is light in the 400nm (deep visible blue) to 700nm (deep visible red) range. While the MultispeQ uses some optical filtration, it is still necessary to calibrate each device against a known PAR sensor to ensure comparability and consistency across devices. We choose to use the LiCOR 190R Quantum Sensor to calibrate against as a long term and well respected PAR sensor.

A light box with 5 LEDs (red, green, blue, orange, and 940nm) is set up with a location to place the MultispeQ or LiCOR PAR sensor. The MultispeQ is then connected to the light box via the USB-C port. This protocol can initiate the light box sequence by sending a digital HIGH/LOW/HIGH signal over USB-C. Once initiated, the light box and the MultispeQ progress through 6 different light regimes (even light, full sun, cloudy day, fluorescent lighting, under a dense canopy, and white LED). While these regimes are not exactly like their namesake (there's no full sun in the box :) ) the combination of LEDs attempts to mimic the spectra of each of these conditions. So - for each light regime, 4 different intensities are measured, resulting in 24 separate measurements (6 regimes x 4 intensities).

Once the LiCOR and MultispeQ data have been collected for the 24 light conditions, they are fed into a model (multiple linea...
