Fieldpiece AMN2 - Manometer Accessory Head - Manual (Page 2)

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 counter-
clockwise one revolution to open.
4. Connect the AMN2 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 pres-

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 measure-
ment, 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.
Stick Meter
This is the heart of modular expandability. In addi-
tion to being a full functioning multimeter, any acces-
sory head can be used with it.

Accessory Heads
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 whatev-
er the head is measuring. Instead of having to pur-
chase and carry a separate instrument for each
parameter, a technician can use multiple heads and
a single multimeter to do the job.
