EGM-5 Operation Manual V. 1.04 54 support@ppsystems.com
Ship Mode
Yes
Sets the EGM-5 into ship mode. We recommend putting the EGM-5 into ship
mode when transporting/shipping the instrument to avoid accidental power up.
No
Cancels out and the EGM-5 does not go into ship mode. Display returns to
Setting 4 Menu.
Important Note
In order to get the EGM-5 out of “Ship Mode” you must first connect the power supply/charger to the EXT
POWER jack before turning the instrument on. If you do not have the power supply/charger connected
you will not be able to power up the instrument.
Processes
This menu handles the various processes of the EGM-5.
Processes Menu
SRC
Starts the Soil Respiration Chamber (SRC) process.
CPY
Starts the Canopy Assimilation Chamber (CPY) process.
Custom
Starts the Custom process (for use with customer’s own chambers).
Injection
Starts the Injection process using the “Sample Injection Kit” from PP Systems.
Static
Starts the Static process.
Main
Returns to the Main Menu.
Status Box
Any information or error messages are displayed here.
SRC (Soil Respiration Chamber) Process
This process is used in conjunction with our SRC-2 Soil Respiration Chamber for measurement of closed-
system soil CO
2
efflux. In the SRC process, the respiration rate (g m
-2
hr
-1
) is calculated by measuring the
rate of change (increase) in the chamber CO
2
concentration over a period of time. The EGM-5 calculates
both a linear fit and a quadratic fit to the measured data. The data is checked in the quadratic fit to
determine if the data is linear.
While the EGM-5 is in the SRC measuring mode, additional data is added to the output data string:
change in CO
2
(dC), process time (dT), Linear respiration rate (L), and Quadratic respiration rate (Q).
