Support PD Fast Charge

The UD24 Tester supports PD (Power Delivery) fast charging. An illustration shows the tester connected between a power adapter and a smartphone displaying 72% charge.

UD24 Line Resistance Measurement Function

Support Android/Type-C Cable Resistance Detection:

To measure line resistance, first measure the battery's no-load voltage, then add an output load. The current battery internal resistance can then be read.

The internal resistance calculation formula is: (no-load voltage - loaded voltage) / current = battery internal resistance.

Illustrations show the UD24 tester connected for line resistance measurement, with displays showing Vol:004.918V, Cur:000.000A (no-load) and Vol:004.918V, Cur:001.585A (loaded), with C-RES readings like 3.1mΩ and 0177mΩ.

USB and Type-C Test Application Range

The UD24 Tester can connect and test various USB and Type-C interfaces and battery devices. It supports multi-port design, multi-use, and multi-play scenarios.

Application Examples: Type-C power bank, Type-C computer, Type-C smart socket, Type-C charger, Ordinary USB charger, Notebook, Desktop PC, Power Bank etc., Type-C phone, Type-C load, Type-C tablet, Type-C notebook, Mobile/iPad, USB adjustable load, USB fan, USB keyboard, USB light/mouse/mobile hard disk, etc.

UD24 DC Voltmeter Use Function

The UD24 functions as a DC voltmeter, displaying parameters like Voltage, Current, Power, Resistance, Energy, and Capacity.

DC Meter Display: Shows Battery capacity/DC power detector readings: Vol:15.023V, Cur:00.999A, Pwr:15.007W, Res:12.434Ω, Ene:1006.0KWh, Cap:83657Ah. Also shows Price, Cost, Co2, Kg, and Timing.

DC Percentage Display: Shows Battery capacity/DC power detector readings: Vol:019.850V, Cur:003.630A, Pwr:072.050W, Res:00003.5Ω, Ene:0006.60KWh, Cap:0062.05Ah, with an 80% indicator. Timing:021:39:39, BAT-R:005.8mΩ.

Battery Power Percentage

The meter allows users to set battery type, full voltage, and discharge voltage. It calculates the percentage based on user-defined thresholds and changes the color of the percentage indicator accordingly.

Display Colors: More than 30% is green, less than 30% is yellow, and less than 10% is red.

When the display range is between 1% and 100%, the POWER red light on the panel lights up, and the relay output interface activates. When it exceeds the 1%~100% range, the red light turns off.

The device uses a low-level output to disconnect the current path, ensuring safety during charging and discharging. It helps prevent battery damage from overcharge and overdischarge and can be used for overvoltage and low voltage disconnect protection.

An illustration shows the "Battery Power Percentage" display with color zones: Green (More than 30%), Yellow (Less than 30%), Red (Less than 10%).

Battery Internal Resistance Detection Function

To detect battery internal resistance, first measure the battery's no-load voltage, then add an output load. The current battery internal resistance can then be read.

The internal resistance calculation formula is: (no-load voltage - loaded voltage) / current = battery internal resistance.

Illustrations show the UD24 tester connected to a battery and a load resistor for internal resistance measurement. Displays show Vol:019.850V, Cur:000.000A (no-load) and Vol:019.850V, Cur:003.630A (loaded), with BAT-R readings like ----mΩ and 0016mΩ.
