Introduction
The DFT-6600 Tester is specially designed for verification discharge testing, capacity testing, daily battery string
maintenance, engineering acceptance and other DC power supply load capacity testing of battery string:
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 efficient resistor as the discharge load, which completely avoids
the red-heat phenomenon for more safe and reliable and nonpolluting.
The whole tester is controlled by a microprocessor on LCD display & English menu.
The host design is novel, small size, light weight and portable.
The entire constant current discharge process is automatically completed after the various discharge
parameters are set,
Fully smart control to make the entire discharge process safer.
The DFT-6600 Tester is to make the discharge test work simple and easy, which is not only to greatly reduce the
labor intensity of professional maintenance personnel, but also to improve the scientific and smart control
discharge testing.
The DFT-6600 Tester combines battery testing technology, Wi-Fi communication technology, computer
information processing and other technologies, to launch a new generation of discharge tester with Wi-Fi
single-cell detection functions:
By the use of Wi-Fi transmission single-cell voltage acquisition system, it can be short distance Wi-Fi
communication transmission data, data acquisition speed, high precision, strong anti-interference ability, easy
operate, which can also record the battery discharge process of each time period of voltage changes, and effectively
avoid the error caused by the connection and connection cable damage and other safety hazards.
The single-cell bridge voltage Wi-Fi collection between the battery connection wire is to ensure that even if
individual connectors loose in the discharge process may cause large connection resistance, it can also monitor
individual voltage abnormalities, Eliminate hidden dangers in time, and prevent major accidents such as fire caused
by overheating at the joint, which enhance the stability and reliability of the system, and expand the use scope of
the DFT-6600 Tester.

There are traditional main 2 ways to monitor the voltage of a single-cell: manual and wired automatic
measurement.
Due to manual measurement inability to achieve continuous and synchronous in time with 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
detection of a string of 24 single-cells as an example, it is necessary to lead 25 single test cables from the host to
connect to the battery string, and its length is less than one tester, more than ten tester, which not only increases the
purchase cost of the users, 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 tester is used of single-cell detection & string dishing with Wi-Fi transmission single-cell voltage acquisition
system, which effectively overcomes the shortcomings of the traditional single-cell battery voltage monitoring
method. Wi-Fi transmission single-cell voltage acquisition system, each Wi-Fi transmission single-cell voltage
acquisition system can simultaneously collect multiple sections of single-cell voltage, and Wi-Fi send the detection
results to the host, convenient for the construction of the test environment and measurement control and data
distribution.
So the use of new single-cell detection & entire string discharge tester to monitor the single-cell, without the need
to connect the single-cell and the host, you can directly detect, easy use, reduce the purchase cost of users
