Pre-Test
This is used to test the link between the Range Finder
handheld unit and the satellites IHD and GAS.
The results are shown in the following screen and include:
· Serial number of the IHD or GAS unit.
· Battery capacity at IHD and GAS units.
· RSSI level measure during the Pre-Test.
· Overall result of ‘OK’or ‘NOK’for Pre-Test Pass or
Fail.
The bottom row shows:
· The Zigbee RF channel used for Pre-Test.
· The transmit power used for Pre-Test.
· The battery status of handheld unit.
Pre-Test transfers all the test settings from HHT to the IHD
and GAS units for current session, so it is important to get
an OK from this test in order to perform any further tests.
Press ESC key to exit the test and go back to menu
screen.
Main Menu Screen 1
Use navigation keys to scroll through various menu
options. Use keys to scroll between ‘IG’and ‘I’option.

The battery symbol indicates the capacity or charging
status of the battery of the handheld. Further details of

Data Logging Configuration (Data Logger)
The HHT will record the results from Test-A/B and Energy
Scan into built-in storage. After exiting the welcome screen
the data logging config screen will appear which enables
the operator to enter the SITE ID for the current session.
The SITE ID will be stored with the test results of the cur-
rent session (more details in the user manual).
At every new site, change the SITE ID by navigating to
EDIT option on screen using keys and press
OK. The SITE ID is an alphanumeric field of 16 characters
and can be edited by using keys.
Once the SITE ID is changed press OK key on keypad to
hear a beep from device as confirmation.
Please enter a unique SITE ID for each location as this is

The ‘CDT’option has a valid range of 10 to 120 seconds.
This value is the countdown time used during Test A and
Test B. if this setting is changed here, the change will be
volatile (i.e. CDT will be reset to the default value after
power up) The PIN protected configuration settings are
described in detail in the user manual.
The RangeFinder has 10 built-in profiles of all the settings
which are required to perform tests which could be as-
signed to each device (HHT/IHD/GAS) individually. To
assign the setting to any device navigate to the device
name using keys and press OK. Scroll through the
profiles and using keys. Press OK to set that profile
to the device. Details can be found in the user manual.
One profile can be shared by two or all the devices.
Test B
Test B is similar to Test A except it tests the link between
the HHT and the IHD and GAS units on channels 20,24 and
25. The result screen is as shown:
Energy Scan
An energy scan across all channels specified by the 2.4GHz
802.15.4 standard is performed and the result is shown. The
Energy Scan results for each channel are painted on the
screen as the scan progresses.
The channel number ‘0’corresponds to channel 11 of the
ZigBee 2.4GHz RF spectrum. The channels which are
tested in Test A and B are highlighted.
Test A
Test A checks the link between HHT and the IHD and GAS
units on channels 11,14,15 and 19. At the start of test a
countdown timer gives the operator a chance to place the
HHT unit in the test location and move away. Count down
time can be changed in the Configuration Settings Screen.
A link PASS or FAIL is indicated by a or cross
respectively in the right hand column and the link which
failed is highlighted. The red backlight turns ON if link
failure occurs on two or more channels.
