UD24 - Multifunction USB-C & DC Digital Tester 5-32V

The Atorch UD24 is a high-precision power analyzer that goes beyond standard USB testers. Thanks to its wide compatibility (USB-C, USB-A, and DC terminals), it allows you to measure voltage, current, and capacity for a vast range of devices, from simple smartphones to battery packs up to 32V.

The standout feature of the UD24 is the integrated Bluetooth module, which allows you to view real-time data and record discharge graphs directly on your smartphone (Android/iOS) or PC, making long-term diagnostics simple and accurate.

🔬 Main Features:

  • Multi-Interface: USB-A, Type-C, and DC Inputs/Outputs (5.5mm/Screw Terminals).
  • Wireless Monitoring: Bluetooth connection for remote analysis via dedicated App.
  • HD Color Display: 360° rotatable for easy reading in any position.
  • 6-Digit Measurement: High resolution to detect even the smallest variations in consumption.
  • Intelligent Protection: Programmable alarms for overvoltage, undervoltage, and overcurrent.

Manual

Characteristics:

1) Voltage measurement range: 5V ~ 32.0V; Current measurement range: 0.00 ~ 5.10A
2) Timing time: 999 hours 59 minutes 59 seconds
3) Input interface: Type-C/Micro USB/USB; Output interface: Type-C/USB
4) Timed charging reminder setting: 24 hours countdown any value set
5) USB D+ voltage range: 0V~2.99V; USB D- voltage range: 0V~2.99V
6) Refresh time: > 500mS/times; Measuring rate: about 0.5 times/sec
7) Alarm mode: siren sound + prompt display dual warning
7) 2.4 inch color digital display
8) Self-consumption current: <0.02A; Operating temperature: -10~+60°C

Battery charge percentage:

1) The instrument can freely set the battery type according to the user in the background, the corresponding full voltage value and discharge voltage
2) 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
3) Display (more than 30% green, less than 30% yellow, less than 10% red);
4) When the display range is between 1% and 100%, the red POWER light on the panel lights up, and the relay output interface exits at this time
5) 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
6) Refresh time: > 500mS/times; Measuring rate: about 0.5 times/sec
7) The plug-in electrical appliance outputs a low level to disconnect the current path to ensure the safety protection of the battery for charging and discharging.

How the buttons work:

Battery data:

1) Long press the "M" key, the OFF on the screen will flash, click the "-" button or
2) Press this operation to set other parameters, wait a few seconds, the screen will appear: "OK!", the setting is complete!
3) Or long press the "M" key, the numbers on the screen will flash, you can freely choose to set the parameters!

How to connect Bluetooth:

1) According to the connection method shown on the left, first measure the current no-load voltage of the battery, and then add the output load. At this time, you can read the current internal resistance of the battery
2) The internal resistance calculation formula of this table: (loaded voltage with no-load voltage) / current current = internal resistance of the battery

1) Compatible with Android and ios phones
2) Use the Bluetooth function of your mobile phone to wirelessly connect the product, with the included mobile APP software, Get more measurement and control details.
3) Compatible with Android and ios phones
4) Please download the mobile APP software, only support Android 5.0 and above. Download related links
5) Then install the E-meter APP software on your phone
