Getting Started
Installing Batteries
The AXD 550 uses three (3) AA size
nonrechargeable batteries. The unit was shipped
with batteries not installed. You will find the
batteries in the instrument package.
Figure 1: Back view of instrument
To install the batteries:
• Loosen the battery cover screw on the back of
the instrument (Figure 1).
• Slide the cover up and lift it out.
• Install the batteries over the pull strap, taking
care to observe each battery’s polarity.
• Replace the cover and tighten the screws.
Note:
When the batteries become low, the LCD
will show
[ LO BATT ]
above the reading. From
that point, you will have about one hour of normal
use left. If
[ ]
comes on continuously and
replaces the reading, the battery voltage is too low
for accurate measurements and the meter will turn
itself off.
Always keep a replacement set of new batteries
available.
Preparing the Instrument
The unit is shipped with its auto shut-off feature
enabled. This setting will automatically turn the
unit off after a twenty-minute period of keyboard
inactivity. To disable this feature, follow the
instructions in the menu selections section of this
manual.
Attach hoses to the pressure ports at the top of the
instrument. Do
not exceed maximum pressure.
If desired, attach the wrist strap to the bottom of
the instrument.
Attaching the Optional Pitot Probe
To attach the probe for measuring air velocity:
• Remove the Pitot probe and rubber tubing from
their carrying case.
• Remove the protective caps from the probe and
save them for re-storing the probe later.
• Attach one section of flexible tubing to the
probe’s static pressure port, and another to the
probe’s total pressure port.
• Identify the (+) and (-) pressure ports at the top
of the AXD 550.
• Attach the tubing from the total pressure port of
the Pitot probe to the (+) port of the
MicroManometer.
• Attach the tubing from the static pressure port of
the Pitot probe to the (-) port of the
MicroManometer.
• Check to ensure that all tubing connections are
tight (see Figure 2).

Attaching a MicroPrinter
Connect the 8521 to the AXD 550 before turning
on the instrument. The connector on the AXD 550
is a telephone-style jack.
