9999 Counts Multimeter and USB Tester

DMT-99 Recording ModeFNIRSI multimeter can plot measured value ripple that changes over time is drawn, and the fluctuation of voltage or current over time can be observed. 8 measured values can be recorded, and the Max and Min measurement values are displayed. DMT-99 Monitoring modeCustom thresholds can be set in multimeter monitoring mode, and a warning will be issued if the voltage exceeds or falls below the set threshold. Solving hungerBuilt-in 1500 mAh rechargeable battery allows the multimeter tester to work longer. No more manually replacing bulky, unfindable disposable batteries, the Type-c port renews energy at any time.

Updated USB TesterFNIRSI 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 TesterFNB58 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
