Instructions F16AD, F16ADN
4Read these instructions before using the gauge. Configuration
may be easier before installation. Contact the factory for assis-
tance.
4These products do not contain user-serviceable parts. Contact
us for repairs, service, or refurbishment.
4Gauges must be operated within specified ambient temperature
ranges.
4Outdoor or wash down applications require a NEMA 4X gauge or
installation in a NEMA 4X housing.
4Use a pressure or vacuum range appropriate for the application.
4Use fittings appropriate for the pressure range of the gauge.
4Due to the hardness of 316 stainless steel, it is recommended
that a thread sealant be used to ensure leak-free operation.
4For contaminated media use an appropriate screen or filter to
keep debris out of gauge port.
4Remove system pressures before removing or installing gauge.
4Install or remove gauge using a wrench on the hex fitting only.
Do not attempt to turn gauge by forcing the housing.
4Good 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
diaphragm may cause silicone oil inside sensor to react with
oxygen.
Bipolar ranges read positive pressure and vacuum in the same
units, and zero with the gauge port open.
1000 psi and higher sensor are a sealed reference type. They read
zero with the gauge port open are internally referenced to 14.7 psi.
Functionally similar to gauge reference sensors.
Absolute reference gauges read zero at full vacuum and
atmospheric pressure with the gauge port open. With an open
gauge port the readings will vary continuously due to the effects of
barometric pressure.
Range Codes
The range code is part of the gauge model number and indicates
the default range when the gauge is ordered.
Selectable Ranges
Engineering units may be changed to any of those listed in the same
sensor range as shown in the range table.
Conversion
Engineering units are calculated from the factory default unit to the
newly selected units. The ranges listed under the psi sensor range
are rounded off.
The AD series is powered by 8-24 VAC 50/60 Hz or 9-32 VDC.
The type and magnitude of the supply voltage have negligible
effects on the gauge calibration as long as it is within the voltage
ranges stated above. No polarity needs to be observed when con-
necting a power supply. An inexpensive unregulated low voltage AC
or DC power supply can be used.
After the gauge is installed, route the wires away from heat sources
and moving equipment and connect the low-voltage power source
to the gauge wires.
Ensure that the gauge supply voltage does not fall below 8 VACRMS
if AC power is used, or 9 VDC if DC power is used. Operation with
less than these values may cause erratic or erroneous readings.
When operating multiple gauges from the same power supply, refer
to the mA rating in the specifications to ensure adequate power.
Note that standard 24 VAC transformers with small loads often
operate at voltages well over the gauge's 24 VAC limit.
Power-Up
Press and hold the front button for approximately 1 second.
The display is tested, the default full-scale range is indicated, the
full-scale range in the selected units are indicated, the display is
tested again, then the actual pressure and units are displayed.
Power-Up With Zero
This applies to gauge reference models only. Absolute reference
gauges do not use the zero feature since they read atmospheric
pressure under normal conditions.
Be sure the gauge port is exposed to normal atmospheric pressure
and no pressure is applied. The zeroing function is only activated
at each power-up and the stored zero correction is erased when
the gauge is shut off.
Press and hold the front button. The display is tested and then oooo
is displayed. The gauge is now zeroed. Release the button and the
full-scale range in the selected units are indicated, the display is
tested again, then the actual pressure and units are displayed.
Attempting to zero the gauge with pressure greater than approxi-
mately 3% of full-scale pressure or vacuum applied will result in an
error condition, and the display will alternately indicate Err 0 and
the actual measured pressure. The gauge must be powered down
to reset the error condition.
Normal Operation
Following the start-up initialization, the display indicates the pres-
sure reading updated approximately 3 times per second. The gauge
may be left on continuously or shut off as desired.
If excessive vacuum is applied to a pressure-only gauge, the display
will indicate -Err until the vacuum is released.
Applying vacuum to a gauge designed for pressure may damage
the pressure sensor. If excessive pressure is applied (112.5% over
range), an out-of-range indication of 1 – – – or 1.–.–.– will be
displayed depending on model.
Display Backlighting (BL models only)
Display backlighting is on whenever the gauge is on.
The display backlighting will not be apparent under bright lighting
conditions.
Minimum and Maximum Readings
Gauges are normally configured with minimum and maximum
capture functions enabled. One or both can be disabled in the User
Configuration mode.
Minimum and maximum readings are continuously stored and
updated whenever the gauge is on. The stored readings can be
manually cleared if desired. The MAX and MIN memory is also
cleared whenever the gauge is off unless configured to save the
readings.
Press and hold the button for about 1 second until MAX is displayed
alternating with the units. The maximum reading will be continu-
ously updated. The gauge may be left in this mode.
After MAX is displayed, press and hold the button for about 1 sec-
ond until MIN is displayed alternating with the units. The minimum
reading will be continuously updated. The gauge may be left in this
mode. If excessive vacuum is applied to a pressure-only gauge
while in this mode, the display will indicate -Err until the MAX/MIN
readings are cleared.
After MIN is displayed, press and hold the button again for about 1
second until * * * * is displayed. The MAX and MIN memory is not
erased and the gauge returns to normal operation with the display
indicating the current reading.
Press and continue to hold the button until the display indicates clr
MX/MN (about 3 seconds total) and then release the button. Both
maximum and minimum values are cleared and the gauge returns
to the normal mode and displays the current pressure.
Shut-Down
To shut off the gauge manually at any time, press and hold the button
until the display indicates OFF (about 5 seconds) and then release.

Accessing the Internal Buttons
Remove the 6 Phillips screws on the back of the unit.
The two internal buttons are located near the lower right and left
corners of the circuit board.
Engineering Unit Selection
Engineering unit selection (except compound ranges) is done
via internal buttons to help prevent accidental or unauthorized
changes. The selected engineering unit is stored in non-volatile
memory and will be retained even with the gauge off or batteries
removed. The available engineering units depend on the sensor
range and display resolution.
Compound (inHg/PSIG) gauges must be changed to display single-
unit vacuum/pressure readings in the Advanced Configuration mode
before different engineering units can be selected.
The default engineering units are mathematically converted to the
newly selected engineering unit. When the gauge is powered up,
the originally configured range is displayed and then the conversion
with the selected engineering unit is displayed.
Powered the gauge up by holding the front button for 1 second.
Press and hold the internal UP button.
Release the button when the engineering units begin to flash.
Use the UP and DOWN buttons to scroll through the list of engineer-
ing units available for the pressure range of the sensor.
When the desired units are displayed, press and release the front
button to save the selection and return to normal operation.
Note: The gauge will automatically revert to normal operation if no
buttons are operated for approximately 15 seconds.
Replace the rear cover taking care not to pinch the power wires
between the cover and the case.
Instructions F16AD, F16ADN

Advanced ConfigurationBasic Configuration
All gauges are factory calibrated using NIST traceable calibration
equipment. Calibration is not required before using the gauge.
Calibration intervals depend on your quality standards, but annual
re-calibration is customary.
Calibration equipment is not required to zero gauge reference
ranges. Absolute reference ranges may be zeroed with application
of full vacuum.
Span calibration should only be performed using appropriate cali-
bration procedures with calibration standards that are at least four
times more accurate than the gauge being calibrated.
The calibration system must be able to generate and measure pres-
sure/vacuum over the full range of the gauge. A vacuum pump able
to produce a vacuum of 100 microns (0.1 torr or 100 millitorr) or
lower is required for vacuum and absolute gauges.
Connect gauge to a 8-24 VAC 50/60 Hz or 9-32 VDC power supply.
Allow the gauge to equalize to normal room temperature for
approximately 20 minutes before calibration.
Remove the rear cover to gain access to the UP and DOWN buttons
located near the lower right and left corners of the circuit board.

ing units as well as percent (PCT). For greatest accuracy, use the UP
and DOWN buttons to select engineering units for calibration with
highest resolution (highest number of display counts). Press and
release the front button when the appropriate engineering units are
displayed. Suggested units are listed below.

The display will then indicate the currently applied pressure in the
engineering units selected for calibration.
UP and DOWN Button Operation
Each time one of the calibration buttons is pressed and released
quickly, a small change is made to the digitized pressure signal. It
may take more than one of these small changes to result in a single
digit change on the display.
To make larger changes, press and hold the appropriate calibration
button. After about one second, the display will begin to change
continuously. Release the button to stop. Then make fine adjust-
ments by pressing and quickly releasing the calibration buttons as
previously described.
Gauge Reference Pressure Gauges
Apply zero pressure by venting the gauge port to atmosphere. The
character display will alternate between ZERO and CAL. Adjust for
a display indication of zero using the UP and the DOWN buttons.
Apply full-scale pressure. The character display will alternate
between +SPAN and CAL. Adjust for a display indication of full-
scale pressure using the UP and the DOWN buttons.
Apply 50% full-scale pressure. The character display will alternate
between +MID and CAL. Adjust for a display indication equal to
50% of full-scale pressure using the UP and the DOWN buttons.
Gauge Reference Vacuum Gauges
Apply zero pressure by venting the gauge port to atmosphere. The
character display will alternate between ZERO and CAL. Adjust for
a display indication of zero using the UP and the DOWN buttons.
Apply full-scale vacuum. The character display will alternate
between +SPAN and CAL. Adjust for a display indication of full-
scale vacuum using the UP and the DOWN buttons.
Apply 50% full-scale vacuum. The character display will alternate
between +MID and CAL. Adjust for a display indication equal to
50% of full-scale vacuum using the UP and the DOWN buttons.
Absolute Reference Gauges
Apply full vacuum to the gauge. The character display will alternate
between ZERO and CAL. Press the UP and DOWN buttons to obtain
a display indication of zero.
Apply full-scale pressure. The character display will alternate
between +SPAN and CAL. Press the UP and DOWN buttons to obtain
a display indication equal to full-scale pressure.
Apply 50% of full-scale pressure. The lower display will alternate
between +MID and CAL. Press the UP and DOWN buttons to obtain
an indication equal to 50% of full-scale pressure.
Compound and Bipolar Gauges
In addition to the steps described above for pressure gauges, apply
full-scale vacuum. The character display will alternate between
-SPAN and CAL. Adjust for a display indication of actual applied
vacuum using the UP and the DOWN buttons.
For bipolar and –30.00inHg/+15.00psig compound range models
only, apply 50% full-scale vacuum. The character display will alter-
nate between -MID and CAL. Adjust for a display indication equal
to 50% of full-scale vacuum using the UP and the DOWN buttons.
Save Calibration
Once the adjustments are complete, press and hold the front button
until the display indicates - - - - then release the button to store
the calibration parameters in non-volatile memory and restart the
gauge.
Verify the pressure indications at 0%, 25%, 50%, 75% and 100%
of full scale.
Replace the rear cover taking care not to pinch the wires between
the cover and the case.
Remove the rear cover to access the buttons located near the lower
right and left corners of the circuit board.
