Configuration Settings Screen (Config)
Use navigation keys to scroll through different set-
tings. Press OK to select the setting and keys to edit
it.
Once edited again press OK to set the value for the config-
uration setting. If the value is set correctly the device will
beep once to confirm change in the setting.
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.
