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 briefl y appear across the display indicating that both Peak values have been cleared. Both Peak High and Peak Low values will then display the
current applied pressure. Pressing the
(
clear
)
button while either the Peak High icon ( HI ) or the Peak Low icon ( LO ) is displayed will not aff ect the zero
value. If you need to rezero the gauge, you must turn off both peak icons by pressing the
(
peak
)
button.
Zero
If you attempt to zero the gauge while applying a pressure which exceeds the Zero Limit (set in Confi gXP, defaults to 20 PSI),
the command will be ignored and - - HI - will be displayed.
 To Zero the WT Series
Turn off peak indication by pressing the
(
peak
)
button repeatedly until the Peak High icon ( HI ) and Peak Low icon ( LO ) are off . Then press the
(
zero
)
button for at least ½ second when the gauge is vented to atmosphere.
The display will then briefl y fl 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 fi rst relieving system pressure!
 To Clear the Zero Value on the WT Series
Turn off 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.
