Setting the Time
You should make sure that the system time on the porometer
is correctly set. This will make sure the timestamps on down-
loaded readings are accurate (see “How Saved Data is Orga-
nized,” Chapter 4). You can do this manually in the porometer
(see “Time” in Chapter 3), or by using the Leaf Porometer
Utility (see “Setting The Date & Time” in Chapter 5).
Calibration Number
Each sensor head comes with a default five digit calibration
number that can be found on the tag on the sensor head cable
and on the calibration certificate. This default calibration
number has been entered into the leaf porometer readout unit
and will be applied to each measurement until a user initiated
calibration is performed. When a user initiated calibration is
performed, a new calibration number is generated and stored.
This new calibration number will be applied to all subsequent
measurements instead of the default calibration until a new
user initiated calibration is performed or the user requests a
reset to the default calibration.
