Familiarizing Yourself with the Measurement Display
CIRAS-2 is an advanced measurement system incorporating several high precision sensors for
measurement and subsequent calculation of gas exchange. The measurement display features a
Numeric Display, which contains measured data from various sensors, calculated data and Environmental
Control Settings. In addition, there is a large graphic display which can be tailored to meet your viewing
and operational requirements.
LED Tuning
If using the LED light unit, the system will go through an LED tuning procedure when first entering into the
Measurement mode. This process takes approximately 30 seconds and cannot be interrupted. During
this time, CIRAS-2 drives the light unit to a range of different levels in order to establish precise control of
light intensity, accounting for sensor changes over time and small differences between different light units
that may be used with the CIRAS-2. LED tuning may also be performed manually by selecting
Utilities -
LED Tuning - Start
from the menu bar.
Please note
:
1. Ensure that the cuvette and light unit are properly powered and connected prior to starting the
software.
2. Ensure that the light unit is correctly seated above the cuvette window and secure.
3. The cuvette must be closed during this process.
For customers that have our Chlorophyll Fluorescence Module (CFM), LED tuning will be followed by CFM
tuning.
