Preface
The DFT-6300 Tester is specially designed for verification discharge testing of battery string, capacity testing ,
daily battery string maintenance, engineering acceptance and other DC power supply load capacity testing .
Using the latest Wi-fi communication technology, the battery discharge process can be monitored in real time
through the PC monitoring software, and the discharge process of each battery can be monitored.
The power consumption part adopts the new PTC ceramic resistor as the discharge load, which completely avoids
the phenomenon of red heat, and is safe and reliable without pollution.
The whole Tester is controlled by a microprocessor with LCD touch-screen display & English menu, which is
novel design of small size, light weight and portable.
After the various discharge parameters are set, the entire constant current discharge process is automatically
completed., and make the entire discharge process safer.
The DFT-6300 Tester is easy to carry, smart professional design to make the discharge test work simple and easy,
greatly reducing the labor intensity of professional maintenance personnel, but also improve the scientific and
smart discharge testing.
On the basis of the original products, the DFT-6300 Tester combines battery testing technology, Wi-fi
communication technology, computer information processing and other technologies to launch a new generation
of single-cell testing & String discharge tester with Wi-fi single-cell testing functions. The use of Wi-fi
transmission cell voltage acquisition system, can be short distance Wi-fi communication transmission data, data
acquisition speed, high precision, strong anti-interference ability, easy to operate, can record the battery discharge
process of each time period of voltage changes, effectively avoid the error caused by the connection and
connection cable damage and other safety hazards, Wi-fi collection of cell voltage between the battery connection
wire generated by the "bridge voltage", to ensure that there may be individual connectors in the discharge process
loose, etc. and there is a large connection resistance, so as to monitor individual voltage abnormalities, Eliminate
hidden dangers in time, prevent major accidents such as fire caused by overheating at the joint, enhance the
stability and reliability of the system, and expand the scope of use of the product.
There are two main ways to monitor the voltage of a traditional single-cell cell: manual measurement and wired
automatic measurement. Due to the inability to achieve continuous and synchronous manual measurement in time,
more human error and low precision, it is impossible to make a more accurate and objective judgment on the
performance of the battery, and the workload is large. Although the wired automatic measurement improves the
speed and accuracy of data acquisition and reduces the workload relative to manual measurement, but there are
more connections and complex operations, taking the testing of a string of 24 single-cell cells as an example, it is
necessary to lead 25 single-cell test cables from the host to connect to the battery string , and its length is less than
1M, more than 10M, which not only increases the purchase cost of the enterprise, but also because the connection

cable is more and longer, it is easy to cause connection errors, and it is impossible to avoid the safety hazards
such as connection cable damage.
The discharge tester used the Wi-fi transmission cell voltage acquisition system which effectively overcomes the
shortcomings of the traditional cell battery voltage monitoring method. Wi-fi transmission cell voltage acquisition
system, each Wi-fi transmission cell voltage acquisition system can simultaneously collect multiple sections of
cell voltage, and Wi-fi send the testing results to the main device, convenient for the construction of the test
environment and measurement control and data distribution.
The discharge tester can monitor the single-cell battery, without the need to connect the single-cell battery and the
host, you can directly detect, easy to use, reduce the purchase cost of users.

This manual is intended to guide the user in operating the DFT-6300 Tester.
The operator must have the qualification of electrician or above.
The operator should pay special attention to the safety of personnel and equipment during use.
The DFT-6300 Tester belongs to the precision test equipment, in the process of use should be lightly handled,
do not throw and throw, the result of the light will lead to the deformation of the shell, the heavy will lead to
the failure of internal components, affecting normal use.
Avoid splashing liquids onto the surface of the smart control discharge monitoring DFT-6300 Tester to avoid
permanent damage caused by entering the system, and flammable gases may cause explosions.
For your safety, please read the entire contents of this manual before operating the DFT-6300 Tester. The
surveyor should be familiar with the characteristics of the system under test. It is important to take the correct
testing steps to avoid injury to yourself and others in the work area and to detect damage to your equipment.
Ensure that the operator has a comprehensive understanding of the battery, charging system and relative device
starting before using this tester. Before using this tester, be sure to refer to and follow the relevant safety
precautions and test procedures provided by the THOMSON of the equipment under test.
Safety Information: Security information is used to avoid casualties and damage to equipment.
Reading & understanding and comply with the safety information and instructions in this instruction manual,
including follows:
