FNIRSI USB Tester 4-28V 7A LCD USB A&C Voltage Current Power Tester Multimeter with App Software, Fast Charge Detection Trigger Capacity Ripple

【Multi-port USB tester】FNIRSI FNB58 has a 2.0-inch TFT LCD display, integrated USB-A, Micro-USB, Type-C interface. It is a USB voltage and current detection meter with APP software, a mobile communication terminal with gravity sensor and a fast charging trigger 【Multifunction USB Digital Tester】FNB58 uses external 16-bit ADC, PD protocol physical chip. FNB58 USB tester can monitor the voltage, current, power, resistance, capacity, D+/D- voltage etc, it can be used to test the fast charging protocol of chargers 【Fast Charge Protocol Trigger Detection】FNB58 supports QC2.0/QC3.0, FCP/SCP, AFC, PD2.0/3.0, VOOC/WARP, Super VOOC 1.0/2.0 trigger. The above protocols all support automatic monitoring. MTK-PE automatic detection. Support QC2.O->PD2.0 protocol conversion 【Parameter Recording】 Six-digit display of voltage, current and power. 10 sets of switchable capacity, power etc. Support low-speed waveform drawing, 2 sps-100 sps sampling rate. Support ripple drawing, up to 4 M sps sampling rate 【USB tester detection function】The resistance measurement of the wire by the differential pressure method. E-Marker Cable chip reading. DASH Cable data reading. Record of startup time. Onboard temperature measurement. PD monitor. Analog DASH cable 【Note】To support environmental protection and reduce paper use, the FNB58 does not include a printed manual. You can access the manual, firmware updates, and app information via the QR code provided in the packaging Ensure the PD function switch is on, select the correct input port, and use a compatible protocol; if incompatible, the device defaults to 5 V output, which may limit power measurement

FNB58 USB tester is a reliability and safety USB voltage andcurrent detection meter and a mobile communication terminal fast chargingtrigger.

It has a 2.0-inch full-color ultra-wide viewing angle TFT LCD display, integrated USB-A, Micro-USB, Type-C interface.

Use external 16-bit ADC, PD protocol physical chip.

It can be used to measure the power supply or power consumption of products such as USB interfaces, mobile phone chargers, and U disks.

It can be used to measure the charging power of mobile phones and the input and output of mobile power supplies. 

It can be used to test the fast charging protocol of chargers.

This instruction manual includes relevant safety information, warningtips and solutions to common abnormal situations. 

Please read the relevantcontent carefully and strictly abide by all warnings and precautions.

Do not connect the monitoring interface to a power supply exceeding 28V.

Do not connect the PC connection port to a power source exceeding 16v.

Only one pair of monitoring interfaces (one input port,one outputport) can work at the same time. When there is a pair of monitoring interfaces working, it is forbidden to connect to the equipment onother monitoring interfaces. (Except the PC connection port, the PC port can be connected to an external power supply).

When using the fast charge trigger module,please do not connect equipment that cannot withstand high voltage to any monitoring interface.

After using the PD trigger/monitor/conversion/read E-Marker cablefunction, please turn the PD communication switch in the lower rightcorner back to the OFF position.

Do not charge the phone after the fast charge is triggered.
