Installation Precautions, Ranges and Engineering Units, Basic Operation
Types of Gauges
Gauge reference sensors always read zero with an open gauge port.
Ranges 1000 psi and higher use a 14.7 psi sealed reference sensor.
They are functionally similar to gauge reference sensors.

Installation Precautions
4 Read these instructions before using the gauge. Configuration may
be easier before installation. Contact the factory for assistance.
4 These products do not contain user-serviceable parts, except
batteries. Contact us for repairs, service, or refurbishment.
4 Gauges must be operated within specified ambient temperature
ranges.
4 Permanent installations must be indoors only. Outdoor or wash
down applications require installation in a NEMA 4X housing.
4 Use a pressure or vacuum range appropriate for the application.
4 Use fittings appropriate for the pressure range of the gauge.
4 Due to the hardness of 316 stainless steel, it is recommended
that a thread sealant be used to ensure leak-free operation.
4 For contaminated media use an appropriate screen or filter to
keep debris out of gauge port.
4 Remove system pressures before removing or installing gauge.
4 Install or remove gauge using a wrench on the hex fitting only.
Do not attempt to turn gauge by forcing the housing.
4 Good design practice dictates that positive displacement liquid
pumps include protection devices to prevent sensor damage
from pressure spikes, acceleration head, and vacuum extremes.
p Avoid permanent sensor damage! Do not apply vacuum to non-
vacuum gauges or hydraulic vacuum to any gauges.
p Avoid permanent sensor damage! NEVER insert objects into
gauge port or blow out with compressed air.
Gauges are not for oxygen service. Accidental rupture of sensor dia-
phragm may cause silicone oil inside sensor to react with oxygen.

Power-Up and Normal Operation
Your gauge is ready to use. It was factory
calibrated just prior to shipment with bat-
teries installed.
Press and hold the center power button
for approximately 1 second. The display
is tested.
The full-scale range in the factory default
units is shown first. If the units were
changed by the user, then the full scale
range in the selected engineering units is
displayed next.
The display test is briefly shown again.
The actual pressure and units are displayed.
The gauge is ready for use with readings
updated approx. 3 times per second.
For gauge reference models occasional
flashing of the minus sign is normal and indi-
cates the gauge is at zero pressure. Absolute
gauges only display zero at full vacuum.
Display Backlighting (BL Models Only)
Display backlighting can be turned on by momentarily pressing
a button whenever the gauge is on. This also restarts the auto
shutoff timer.
F20BBL: The backlighting will turn on for 1 minute and then auto-
matically shut off.
F22BBL: The factory default on-time is 1 minute, but setup allows
setting it to 1 to 255 minutes, or to 0 to disable backlighting.
The red LED display backlighting will not be apparent under bright
lighting conditions.

Zero the Display (Gauge Reference Only)
Absolute reference gauges do not use the zero feature since they
read atmospheric pressure under normal conditions.
Be sure the gauge is in the normal operating
mode. The gauge port must be exposed to
normal atmospheric pressure with no pres-
sure or vacuum applied.
Press and hold the Zero/Clear button.
Continue to press the Zero/Clear button until
oooo is displayed then release the button.
The gauge in now zeroed.
Occasional flashing of the minus sign with
zero pressure/vacuum is normal.
The stored zero correction is erased when
the gauge is shut off.
Shutoff
t
The auto shutoff timer starts at power up and resets whenever any
button is pressed. The default time is 5 minutes, but can be set for
a variety of times. If on/off operation is selected, the gauge will stay
on until manually shut off or the batteries are depleted. Turn gauge
off when not in use to conserve battery life.
When an auto shutoff time is used, the
OFF
display indicates
five seconds prior
to shutoff. Press the power button to keep
the gauge on.
To shut the gauge off manually, press and
hold (about 5 seconds) the center power
OFF
button until
is displayed.
Error or Out-of-Range Indications
Attempting to zero the gauge with pressure
greater than approximately 3% of full-scale
pressure or vacuum will result in an error
condition. The display will alternately indi-
cate Err 0 and the actual pressure. The
gauge must be powered down to reset the
error condition.
If excessive vacuum is applied to a pres-
sure-only gauge, the display will indicate
-Err until the vacuum is released. Applying
vacuum to a pressure-only gauge can dam-
age the pressure sensor.
If 112.5% over range pressure is applied
, an out-of-range indication of 1 – – – or
1.–.–.– will be displayed depending on model.
