The ADMN2 is a portable dual port manometer
accessory head. The ADMN2 is capable of taking
gas pressure as well as static pressure. The
ADMN2 also has a zero adjust. The auto-power-off
function conserves battery life, but can be disabled
for data logging if desired.
The ADMN2 will allow you to take gas pressure
between -60inWC and 60inWC. The ADMN2 can
measure P1 or P2 pressure readings or the difference between P1 and P2. The ADMN2 also has two
different measurement scales: inWC (inches of
water column) and mBar. Static pressure is possible
with the resolution of 0.01inWC or 0.01mBar.

including battery
1. Connect to COM and Volts jacks using any
Fieldpiece test leads with removable probe tips.
For Fieldpiece “stick-style” meters, EHDL1, or
DL3, slide the head directly over the meter.
2. Select the mVDC range.
3. Zero the ADMN2 by pressing the ZERO button
just before taking the pressure readings, while
at ambient pressure. This will zero both P1 and
P2.
4. Connect a single hose to get the gauge pressure relative to the ambient or ZERO pressure.
5. Connect both hoses if you want to see relative
pressure, P1 minus P2.
Resolution Modes (0.1 and 0.01)
There are two modes of resolution on the
ADMN2. For most applications, 0.1 mode will be
fine to use. When measuring low pressures, 0.01
will likely be the best mode for meaningful testing.
The most common circumstance for 0.01 mode is
measuring static pressure across a blower.
6. Select P1, P2, or P1 - P2.
7. Select English (inches of water column) or
Metric (mBar) units.
8. To disable the auto-power-off, remove the rubber covering and flip the switch below. Autopower-off is helpful for conserving the battery;
but if you are data logging with Fieldpiece model
DL3, you will want to disable this feature.
9. If you are in an environment where the temperature is noticeably changing while you are taking
your reading, disconnect the meter from the
hoses and ZERO it relative to ambient pressure
before each reading.
Checking Gas Pressure on a Regulator
1. Screw the brass fitting into the pressure port on
the regulator.
2. Put unit into operation (i.e. turn on the furnace
and have furnace ignite, as if running it in normal operation.)
3. This will give you the pressure coming out of the
regulator.
4. If you suspect high or low inlet pressure into the
regulator, the manometer can hook into the inlet
port in the same manner it can connect into the
outlet port. If you have a dual-port manometer,
you can check both the inlet and the outlet
simultaneously and see the pressure drop
across the regulator.
5. See manufacturer's specification for the specifiOnly when using 0.01 mode, the display of your
meter will show the true measurement X 10. So if
the true measurement is 0.08, your meter will show
0.8. This is done to optimize resolution.

Remove the rubber covering the ZERO button.
By pressing the ZERO button, both the P1 and P2
are zeroed to the ambient pressure. For this reason
the calibration should be done when both P1 and
P2 are disconnected from the hoses in order to
properly calibrate to ambient pressure.

RMA316 Manometer Adapter
Used for 5/16" pressure outlet ports.
1. Shut off main gas supply to furnace.
2. Move the gas valve switch to "OFF" position.
3. Use a 3/32" hex wrench to loosen the outlet
pressure tap screw. Rotate screw counterclockwise one revolution to open.
4. Connect the ADMN2 tubing to the smaller
(3/16") end of the adapter and the other (5/16")
end of the adapter into the of the adapter tube.
5. Slide the 5/16" adapter tube over the outlet
pressure boss (port) to seal. Overlap the pressure boss by at least 3/8" to prevent leakage.
Smaller end (3/16”) of the adapter
connects to ADMN2 tubing. Remove
the installed brass fitting from tube
so the adapter can be inserted.

Accessory heads are the sensors of multiple
parameters measured by technicians every day.
They plug into a mV range (depending on the head)
of a multimeter. The multimeter will display whatever the head is measuring. Instead of having to purchase and carry a separate instrument for each
parameter, a technician can use multiple heads and
a single multimeter to do the job.

Accessory Heads
Modular Expandability
Modular expandability is ability for accessory
heads and meters to change configurations to
match the various needs of an HVAC/R technician.
Accessory heads (the sensors) send out a mV
signal, which represents the value of the measurement, to whatever meter is attached to it. Heads can
attach directly to the top of a Stick meter, DL3 data
logger, or EHDL1. They can also plug into any meter
with mV ranges using ASLS2 leads.

2. Insert ASP2 into drilled or pre-existing 1/4” hole.
3. Use allignment arrow on the ASP2 to direct
probe into the air stream.
4. Read static pressure measurements from “stickmeter”, EHDL1 or record with DL3.
5. Remove probe and patch hole.
