The PEAK key will cycle through the types, where “Lt 1” is Actual, “Lt 2” is Average, “Lt 3” is Average
with peaks, and “Lt 4” is on demand. The UNITS key accepts the format and the display advances
to the logging interval, displayed in seconds.
The PEAK key decrements and the ZERO key increments the logging interval. The UNITS key ac-
cepts the logging interval and the display reverts to normal. Note that when in on demand log-
ging type, the logging interval will not be displayed.
UNITS: Pressing and holding this button causes the XP2i to display information
about the logging state, and to start or stop logging. Immediately after pressing the
UNITS button, the gauge will display the operating mode as one of these values:
The logging memory is clear, data is empty, and the XP2i is idle.
The XP2i is logging data.
The XP2i is logging in on demand logging type.
The XP2i is not logging data but there is room for more data.
The XP2i is not logging data and memory is full.
Authorization is required before additional logging is allowed.
If you continue to hold the UNITS button, the number of bytes remaining in logging memory is
displayed.
Holding the UNITS button even longer will then cause the operating state to change as follows:
•
If the gauge is in a CLR or OFF state, the gauge will briefly display START, begin logging data,
and change its state to ON.
•
If the gauge is in an ON state, it will stop logging, briefly display STOP, and change its state to
OFF.
•
The FULL state will not change by holding the UNITS button. In order to get out of the FULL
state, you must clear the logging memory as shown below.
UNITS + ZERO: Holding these two keys will clear the log-
ging memory of the XP2i. If the gauge is in logging type (ON),
you must first stop logging as described above. When these
buttons are pressed, the gauge will first display its current
state (OFF, CLR, etc), then the number of bytes remaining, and then CLR, indicating the clear action
was successful. Once cleared, the XP2i will be in the CLR state.
