ELT Testing Instructions
Using the Reader
Prior to use, install battery pack into test set. To close, place the battery pack
with the top end in first. Now push down on the bottom end of the battery pack
ensuring that it is firmly in place. Now push the clip firmly towards the bottom of
the test set until it clicks into place. Charge the ELT Test Set battery using the
supplied USB cable connection and wall charger. Charge overnight or for at least
8 hours. Upon power-up, follow on screen directions for initialization and setting
the time. The initialization routine is very important to ensure proper function of
the stylus on the test set screen.
The supplied Sarcalc program version 1.30 or higher (sarcalc.prc) is pre-installed
on the Meazura unit in Flash memory. In the event that the program is lost or
needs to be re-installed, it may be installed using the Palm Desktop application
and the Meazura serial or USB cable. The Sarcalc program software and any
future upgrades will be available for download at www.artex.net.
Select the Sarcalc program by tapping the “Sarcalc” icon shown in Figure 2.
(Note: The exact location of your Sarcalc icon may vary depending on what
other programs or applications are loaded on your Test Set). Select “Measure”
from the initial screen. Connect the reader to the ELT directly with a coax cable
(no attenuator required for test set) or connect the whip antenna.
IMPORTANT NOTE:
PERFORM ALL ELT TESTING IN ACCORDANCE WITH LOCAL OR
NATIONAL REGULATIONS. IF REQUIRED, TERMINATE ELT INTO
A 50-OHM LOAD OR PERFORM TESTING IN AN RF SHIELDED
