Telegesis ZigBee RangeFinder
Test A / Test B:
Telegesis Range Finder tests are designed to evaluate the suitability of deployment of a
Smart Energy device which is why they focus on the ZigBee Smart Energy recommended RF
channels in the 2.4GHz spectrum. Tests A and B are performed on ZigBee SE channels 11, 14, 15
and 19 during Test-A, while the remaining of SE channels 20, 24 and 25 are tested in Test-B.
Although the Rangefinder is designed to assist with ZSE installations, the
Continuous test
and
Energy scan
can be used to analyse the entire ZigBee 2.4GHz spectrum.
At the start of each test-A/B, countdown is activated to give a chance for the operator to
put the HHT in place of simulated test device such as electricity meter and move away from the
meter housing if necessary. This timer is configurable in the Configuration Menu.
To perform tests A or B, navigate to the menu item on
Menu Screen 1
using

keys and press
button for the test start screen to appear. Continuous and

Once the countdown has elapsed, the test starts and the test results are displayed for each
channel for the test as the test progresses. The completion of the test is indicated by a short beep
from the built-in buzzer. The display backlight changes to Red for test failure and to Blue colour if
the test is a pass. Also the failed values will be inverted. For details of the Pass/Fail criteria please
see section
“Interpreting Test Results”.
