MISCELLANEOUS
Miscellaneous is accessed by pressing the MISC button on the Select Menu display.
NOTE: All Miscellaneous changes are recorded when you exit Miscellaneous.
ZERO BAND refers to Display Zero Deadband. Zero deadband is a value below
which the display jumps to zero. This deadband is often desired to prevent electrical
noise from showing up on the display as minor flows or pressures that do not exist.
Display Zero Deadband does not affect the analog or digital signal outputs.
ZERO BAND can be adjusted between 0 and
3.2% of the sensor’s Full Scale (FS).
Press ZERO BAND. Then use SELECT to
choose the decimal with the arrow and the
UP and DOWN buttons to change the value.
Press SET to record your value. Press CLEAR
to return to zero.
Pressure Averaging may be useful to make
it easier to read and interpret rapidly
fluctuating pressures and flows. Pressure
and flow averaging can be adjusted between
1 (no averaging) and 256 (maximum
averaging). These are geometric running
averages where the number between 1 and
256 can be considered roughly equivalent to
the response time constant in milliseconds.
This can be effective at “smoothing” high
frequency process oscillations such as those
caused by diaphragm pumps.
Press PRESS AVG. Then use SELECT to
choose the decimal with the arrow and the
UP and DOWN buttons to change the value.
Press SET to record your value. Press CLEAR
to return to zero.
Setting a higher number will equal a
smoother display.
Flow Averaging: While FLOW AVG appears
on the display, this adjustment has no
application in pressure devices. Changing
it will have no effect on the operation of a
pressure device.
LCD CONTRAST: The display contrast can be
adjusted between 0 and 30, with zero being
the lightest and 30 being the darkest.
Use the UP and DOWN buttons to adjust the
contrast. Press SET when you are satisfied.
Press CANCEL to return to the MISC display.
