STEP Button: During inline testing (tester connects to both PSE and PD), by default the tester’s display
shows voltage, amperage, and then wattage in sequence repeatedly. Pressing the STEP button once
allows you to manually go through these readings one at a time starting from the voltage. This is useful
for monitoring a desired reading in real-time.

PSE: Connection from PSE
PD: Connection to PD

Testing Mode Selector
I - Mode: For inline testing over a long period of time. In this mode, the tester measures PD’s power
consumption (Watts) by connecting the PSE’s port to the tester’s PSE port and then connect the tester’s
PD port to a compatible PD. The tester’s display shows the voltage, current, and power consumption in
sequence. Press the “STEP” button at the front panel to stop the cycle and select the desired reading to
monitor in real-time.
T - Mode: The tester acts like a PD and detects PSE’s PoE standard, PoE mode, and measures the voltage
(no reading for current and power). In this mode, you can also perform inline test by connecting tester’s
PD port to a PD that matches PSE’s specification, but limit the testing time to less than 20 minutes to
avoid overheating the tester. For inline testing over a long period of time, please use “I-Mode”.
