Noyafa PoE Checker Inline PoE Voltage and Current Tester with Cable tester NF-488

• Test the information of the standard PoE device, such as af t standard, power supply voltage, power supply polarity and mode.
• Identify the supply voltage, power supply polarity and mode of non-standard PoE devices.
• Check the short circuit, crossover and open circuit status in the network cable.
• Test the current, voltage and power consumed by DC appliances.
• The loop-back test function of the switch.

Features 1. Test Criteria: Test information on standard PoE devices such as standards, supply voltage, power polarity and mode. 2. Detection voltage: Determine the power supply voltage, power polarity and mode of non-standard PoE equipment. 3. Detecting the network: Check for shorts, crossovers and open circuits in the network cable. 4. Detect current: Test the current, voltage and power consumed by the DC appliance. 5. Detection switch: Loopback test function of the switch.
