PWR/TEST LED
When test is started, PWR/TEST LED is blinking orange
When test is finished, PWR/TEST LED keeps orange
When test is finished ready for next test, PWR/TEST LED
keeps green
WATT/VDC LED
When LED is in
green
, the 3-digit LED display shows the
PoE power in unit of Watt.
When LED is in
orange
, the 3-digit LED display shows the
PoE DC voltage.
When LED is off and Normal/Alarm LED is
green
, the
3-digit LED display shows the value of temperature.
OK/NG LED
When LED is in
green
, it indicates the power from PSE is
able to provide the desire maximum power to PD.
When LED is in
orange
, it indicates the power is not
enough to support the desire maximum power to PD.
When LED is in
blinking orange
, the measurement is
failed and the Current is too high (over 2A).
When LED is off and Normal/Alarm LED is in
orange
, the
measurement is failed and the device is over-temperature
(over 100℃).
Normal/Alarm LED
When LED is in
green
, the LED digits display shows the
value of temperature
When LED is in
orange
, the device is over-temperature
(over 100℃).
Measurement Procedures
Hardware connection
Screw tightly the battery pack and connect the cable
as the illustration. Switch power on at the bottom.
For cable bare wires, these can be clamped into
Power Probing Terminal directly for Mode A (Power via
Pin 1, 2, 3, 6) or Mode B (Power via Pin 4, 5, 7, 8) of
IEEE802.3af standard.
Note: Network cable can not be connected to UTP port
and Power Probing Terminal simultaneously.
Operation Procedure
1. To set desire maximum power from PSE to PD for test.
Push and hold Start/Set(-) Button for 3 seconds to enter for configuration of maximum power limit. It confirms with a beep
sound and the 3-digit LED display start blinking. Press the Start/Set(-) or Start/Set(-) buttons to set the desired power limit
Then, push and hold Start/Set(-) button for 3 seconds to exit the configuration stage.
2. Press Start/Set(-) Button to start power measurement test.
The PWR/TEST LED will start
orange blinking
, and the 3-digit LED display will show the changing power measurement. After
the test is done, if the OK/NG LED is
green ON
, it indicates that the power from PSE could support the desire maximum power.
If the OK/NG LED is
orange ON
, it indicates that the power from PSE could NOT support the desire maximum power.
Note that if PPM-1000 is over 50°C, the test will be prohibited. Wait till it cools down for normal start. Once it starts testing, the
tolerated temperature will be up to 100°C.
3. Press Display/Set(+) Button to show the real-time value or measurement results.
Show value of measurement results while the PWR/TEST LED is
orange
after test.
Press once Display/Set(+) Button to show the value of power measurement when the WATT/VDC LED is
green
.
Press again Display/Set(+) Button to show the value of DC voltage when the WATT/VDC LED is
orange
.
Press again Display/Set(+) Button to show the device temperature when the Normal/Alarm LED is
green
.
Show real-time value (by pressing Start/Set(-) Button) while the PWR/TEST LED is green.
Press once Display/Set(+) Button to show the value of power measurement when the WATT/VDC LED is
green
.
Press again Display/Set(+) Button to show the value of DC voltage when the WATT/VDC LED is
orange
.
Press again Display/Set(+) Button to show the device temperature when the Normal/Alarm LED is
green
.
4. Alarm notification
When Normal/Alarm LED is
orange ON
, it indicates that PPM-1000 is over-temperature (over 100℃). Please stop the
measurement until the device is cool down below 50°C.
