Getting Started
Installing Batteries
The AXD530 uses three (3) AA size non-recharge-
able batteries. The unit was shipped with batteries
not installed. You will find the batteries in the in-
strument package.
To install the batteries:
• Loosen the battery cover screw on the
rear of the instrument.
• 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
Attach hoses to the pressure ports at the top of the
instrument. Do not exceed maximum pressure.
Attaching the Optional
Pitot-Static Probe
To attach the probe for measuring air velocity:
• Remove the Pitot-static probe and rub-
ber tubing from their carrying case.
• Remove the protective caps from the
probe and save them for re-storing the
probe later.
