Product model: CC1. Product type: USB-C voltage and current meter. Product features: Direct meter, black screen when plugged into PD charging , must be connected to a useful device to work Current measurement: bidirectional current measurement function (reverse plugging will measure and display its own working current) Product screen: Color IPS screen with a resolution of 160*80. Input interface: USB-C (TYPE-C 24P). Output interface: USB-C (TYPE-C 24P) Working voltage: DC 4-28V ( 36V). Working current: 0-6A (short-term 10A) Voltage resolution: 0.001V. Current resolution: 0.001A. Capacity record: 0-9999Wh Measurement accuracy: 1% of the range Core sampling ADC chip: INA226 ( 16bit high precision) storage chip: EEPROM (With wear-leveling algorithm, can record offline, save after power failure) USB-C male connector: Customized extended high-conductivity copper interface (can penetrate most mobile phone cases) USB-C female connector: low contact resistance female connector Four-wire Kelvin line resistance measurement function: Need to be used with Weijian UL004 measurement kit (need to be purchased separately) PD monitoring function: realized through software simulation, only for monitoring public version PD, some devices with fast broadcast speed are not compatible Fast charging protocol display: inferred by D+D- voltage and working voltage and current, for reference only and not accurate Product size: about 31.8x16.1x8.1mm (excluding USB-C male connector) Note: This product uses an integrated aluminum alloy CNC shell, not aluminum tube processing. The temperature of the aluminum alloy shell is about 40, and the human body will feel very hot when touched Color: gray Material: ABS Package Contents: 1 * Type C Tester (Different batches have different printed labels) Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
