XP2i DataLogger Gauge Operation
When in data logging mode, XP2i provides data logging capability along with the many of the
features of a standard XP2i. In order to allow operation as a data logger, some of the functionality
of the standard XP2i has been removed. However, using DataLoggerXP, it is possible to switch the
XP2i ‘s mode as needed.
Differences Between the XP2i Data Logger and XP2i
Other than the data logging functionality itself, the changes in gauge behavior while in data log-
ger mode is listed below:
•
Units (PSI, kPA, etc.) are set to the gauge’s default unit and cannot be changed*.
•
The UNITS button is used to start and stop runs
•
The PEAK button is used to store data when in on demand logging type
•
The standard mode serial commands are not supported
•
The backlight will not automatically turn o
•
“No Auto O” mode does not apply – once the gauge is turned on, it remains on until the ON
button is pressed to turn it o.
•

O reference cannot be changed.
•
The unit never fully turns o, aecting storage life – see section 2.5 below for more details.
* Note: The default unit can be changed by selecting Change Units... under the File menu, but
this can only be done when the gauge is in data logger mode.
Logging Parameters
When viewing the logging interval on the gauge, it will always be presented in seconds. Logging
type is indicated by a digit—1 through 4 correspond to actual, average, average with peaks, and
on demand types, respectively. These settings can be adjusted directly on the gauge, allowing
changes in logging congurations without the need of the computer.
Unit Operation
The following buttons and button combinations are used to control the XP2i. Where two keys are
indicated, the operation is executed by pressing and holding down the rst key indicated then
pressing and holding down the second key until the action is completed.
UNITS + ON: Used only when the gauge is turned o, this
causes the XP2i to enter logging type and logging interval
selection mode.
