## Description

Multifunctional load tester for checking DC sources and testing battery capacity, also useful for measuring internal resistance using the 4-wire method. Supports 1-200V, up to 25A and 150W with multiple protections and active cooling. Clearly displays parameters on a 2.4 inch color TFT screen, controllable from buttons, via PC via USB-C or wirelessly via included WiFi and Bluetooth.
CL24R electronic load tester, for testing battery capacity, checking power supplies and evaluating the performance of various electrical devices. It can also be used to determine the internal resistance of batteries, using the 4-wire method.
It supports a wide range of voltages (1V-200V) and currents (up to 25A), with a total power of 150W, offering multiple protections and an advanced heat dissipation system through a radiator and fan.
The 2.4-inch color TFT screen ensures a clear view of the test parameters, and its operation can be achieved through the integrated buttons or through the dedicated application.
This module supports connection to a PC via the USB-C port, being recognized by the PC as a HID device. For use on a PC you will need to use the dedicated application (which we provide in the Download section) which allows not only reading information but also complete control of the module. Alternatively, there is the possibility of using a WiFi or Bluetooth module, which can be purchased separately.
The tester comes with two additional modules: A Bluetooth module and a WIFi module from Tuya.
These allow full control of the device via the SmartLife app. Connecting the modules to the tester is quick and easy using the USB-C port.
Features:
Supports voltages from 1V to 200V and currents up to 25A depending on voltage.
Maximum charging power: 150W (with automatic limitation for high voltage protection).
Advanced protections: Overvoltage, overcurrent, overtemperature and reverse polarity protection.
Capacity and energy measurement: Records up to 999999mAh and 999999mWh.
Active heat dissipation: Fan that runs continuously during use.
Multiple test modes: Constant Current (CC), Constant Resistance (CR), Constant Power (CP), Constant Voltage (CV), internal resistance test, power test, cable test.
Testing 1.5V AA/AAA batteries and 1V batteries as well as Lithium batteries: Allows discharging and checking capacity.
Supports cyclic testing (up to 90 cycles): Requires charge control module.
Precise control via 4 buttons and 2.4 inch TFT color display.
Four-wire wiring mode for more accurate measurements.

Constant power (CP) mode – maintains a constant power during testing.
Constant Voltage (CV) Mode – sets a fixed test voltage.
Battery internal resistance test (BRT) – determines the internal resistance of the battery.
Power Test (PT) – measures and records power consumption.
Cable resistance test (CT) – checks voltage losses on cables.
Optional: Adding a charge control module allows for cyclic testing of batteries (up to 90 cycles).
Use:
Connect the tester to the DC12V 1A/PD12V power supply included in the package.
Selecting the test mode: Use the buttons to navigate through the TFT screen menu.
Connecting the device under test: Follow the four-wire wiring diagram for accurate measurements.
Parameter setting: Configure the desired voltage, current or power.
Monitoring results: The tested values will be displayed in real time on the screen or on the PC if connected to the application.
Automatic protection: In the event of an overload, the device will automatically shut down for safety.
Reset to factory settings:
Turn on the device.
Press and hold the Start button to enter the settings menu.
Select Factory Reset and confirm.
