## Description

USB Tester 4-28V 7A LCD USB A&C Voltage Current Tester Multimeter with Bluetooth, Fast Charge Detection Trigger Capacity Ripple Measurement, PD2.0/PD3.0,QC2.0/QC3.0

## Features

- 【Updated Designed USB Tester】FNIRSI FNB58 USB tester has a 2.0-inch full-color ultra-wide viewing angle TFT LCD display, integrated USB-A, Micro-USB, Type-C interface. It is a high-reliability, high-safety USB voltage andcurrent detection meter and a mobile communication terminal fast chargingtrigger. Gravity sensor, automatically switch the display direction.
- 【Multifunction USB Digital Tester】FNB58 uses 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. FNB58 USB tester can monitor the voltage, current, power, resistance, capacity, temperature, D+/D- voltage etc, it can be used to test the fast charging protocol of chargers.
- 【Fast Charge Protocol Trigger Detection】FNB58 supports trigger detection of various fast charging protocols, QC2.0/QC3.0 trigger, FCP/SCP trigger, AFC trigger, PD2.0/3.0 trigger, VOOC/WARP trigger, 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 Detection and Recording】The highest six-digit display of voltage, current and power, the highest resolution is 0.00001 (V/A/W). 10 sets of switchable capacity, power and time statistics. 1 set of voltage and current curve records, maximum support 9 hours. Support low-speed waveform (voltage, current, D+/D-) drawing, 2sps->100sps sampling rate. Support high-speed ripple (voltage, AC coupling)drawing, up to 4M sps sampling rate.
- 【Other detection functions】FNB58 also has many functions that other USB testers do not have. The internal 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. ☆☆In order to respond to the environmental protection policy and reduce the waste and use of paper, FNB58 does not come with paper manuals.
