Resetting (Clearing) Recorded Peak Values
Peak values can only be cleared when displaying either a Peak High or Peak Low recorded pressure. Press the (clear) button for at least ½ second. Dashed
lines will briey appear across the display indicating that both Peak values have been cleared. Both Peak High and Peak Low values will then display the cur-
rent applied pressure. Pressing the
(clear) button while either the Peak High (
HI
) or Peak Low (
LO
) icon is displayed will not aect the zero value. If you
need to rezero the gauge, you must turn o both peak icons by pressing the
(peak) button.

If you attempt to zero the gauge while applying a pressure which exceeds the Zero Limit (set in CongXP, defaults to 20 psi),
the command will be ignored and “--HI-” will be displayed.

To Zero the XP2i
Turn o peak indication by pressing the (peak) button repeatedly until the HI and LO icons are o, then press the (zero) button for at least ½ second when
the gauge is vented to atmosphere.
The display will then briey ash all dashed lines (
), indicating that it has been re-zeroed. Absolute gauges will now indicate gauge pressure.
!
WaRninG: This gauge can display zero pressure when connected to a source of pressure! Do not rely on the display indication before disconnecting—
it may not be indicating true pressure.
Never disconnect pressure instrumentation without rst relieving system pressure!

To Clear the Zero Value on an XP2i
Turn o peak indication as described above, then press and hold the (zero) button until the display changes from (
) to ( ).
This is especially useful for absolute gauges that have been zeroed to use for gauge pressure measurement.
