forced to negotiate to 100Base-T half-duplex mode, and the final result
displayed by the tester is 100Base-T half-duplex.
POE Test
If the POE is provided by a switch that supports POE, when the power
pairs are on 1, 2 and 3, 6, this power supply method is called "POE
endspan". At this time, use a tester to test, the POE LED will be green, when
the power supply For 4,5 and 7,8, this power supply method is called "POE
midspan". At this time, use a tester to test, and the POE LED is displayed in
red.
Cable test
When the remote probe is not used, and only the main device is used
for cable testing, insert the cable into the cable test port to test whether there
is a LAN device at the other end of the cable. If the LED is on, it means that
the corresponding wire pair is connected to the device. (for example: LED "1
,2" and "4,5" are lit, indicating that the pair "1, 2" and "4, 5" are connected to
the device.)
If you connect the cable to the cable test port of the main tester and the
remote probe, you can observe the LED display to determine whether the
cable pair is connected, whether there is a wrong connection, the cable is a
straight-through cable or a crossover cable.
Cable Tracing
Connect one end of the cable to the cable test port of the main tester,
and use the remote probe to approach the cable will make a tone. If all four
pairs of the cable are wired, the tone will be more stable. The fewer pairs of
cables, The shorter the tone response time. Use this function to detect the
location of the required cable when the cable is bundled or the cable cannot
be determined.
Low Battery Indication
• If the power supply voltage is between 7.3v and 6.8v, the power LED will
flash continuously and slowly, and the instrument will enter the low voltage
mode.
• when the battery power of the tester is lower than 6.8v and cannot work
reliably, the power LED of the tester will flash ten times quickly and then turn
off. All LEDs are off and the tester cannot perform the test.
• Replace the battery to resume operation.
