UD24 2.4"inch USB tester DC5.5 Type-C digital voltmeter ammeter power bank voltage detector volt QC PD electric meter for APP Voltage measurement range: 5V~32.0V Current measurement range: 0.00~ 5.10A Timing time: 999 hours 59 minutes 59 seconds Input interface: Type-C/Micro USB/USB Output interface: Type-C/USB Timing charging reminder setting: countdown 24 hours any set value USB D+ voltage range: 0V~2.99V USB D- voltage range: 0V~2.99V Refresh time:> 500mS/ times> 500mS/ times Measurement rate: about 0.5 times/sec Alarm mode: siren sound + display prompt double warning Display type: large screen with true color digital display with heavy cost 2.4 Chinese and English measurement interface Self-consumption current: <0.02A Working temperature: -10~+60°C -10~+60°C Working humidity: 10~80 (no doubt) 10~80 (no doubt) Working pressure: 80~106kPa UD24 line resistance measurement function Support Android/Type-C cable resistance detection According to the connection method shown below, first measure the current battery no-load voltage, and then add the output load. At this time, you can read the current battery internal resistance The internal resistance calculation formula of this table: (no-load voltage-loaded voltage) / current current = battery internal resistance Battery power percentage The meter can freely set the battery type according to the user in the background, the corresponding full voltage value and discharge voltage If there is no low value, the system calculates the percentage according to the threshold set by the user, and then changes the color of the percentage through the battery symbol Display (more than 30% green, less than 30% yellow, less than 10% red); When the display range is between 1% and 100%, the POWER red light on the panel lights up, and the relay output interface outputs at this time The level is used to control the relay to connect the current path. When it exceeds the range of 1%~100%, the red light goes out at the same time The plug electric appliance outputs a low level to disconnect the current path to ensure the safety protection of the battery for charging and discharging. People avoid the risk of damaging the battery due to overcharge and overdischarge, and it can also be used for other purposes of overvoltage and low voltage disconnect protection.
