Use notice & Reading tips
Use notice
This manual is intended to guide the user in operating the DFT-6700 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-6700 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 charge monitoring DFT-6700 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-6700 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:
Dangerous! Indicates a very urgent and dangerous situation that could result in serious casualties if not avoided.
Warning! Indicates a potentially dangerous situation that could result in serious casualties if not avoided.
Note! Indicates a potentially dangerous situation that may result in general personal injury if not avoided.
Significant! Indicates a potentially hazardous situation that could result in damage to the test equipment if not
avoided.
Prompt! Do not operate the Air (Control) Switch during charge

Important safety guidelines
Warning
Explosion hazard! The gas produced by the battery is extremely explosive.
Reading & understanding and follow all guidelines with the tester, battery, and any other equipment near the
battery.
No Smoking & No lighting matches, and placing metal tools near or creating sparks near the battery are
prohibited.
The terminals should be cleaned before using the tester. Take care to protect your eyes, nose and mouth when
cleaning. Soda and water can be used to neutralize acidity to reduce the corrosiveness of the air.
Do not place the tester in rain or snow or in a humid environment.
Do not allow battery gas or sulfuric acid to touch the tester's housing.
Never charging, testing, or loading to a frozen battery. The battery should be thawed and warmed to room
temperature before performing the above operations. Charging or testing a frozen battery can cause the battery
to explode and injure people.
Before performing the test, confirm that all test connectors are connected according to the guidelines.
Make sure that the two battery clips are securely connected to the battery.
Battery explosions can cause casualties.
Warning!
Prevent burns
The current generated by the battery short circuit is enough to melt down various ornaments and make them weld
to metal. So please remove various ornaments while working near the battery.
Any short circuit will result in injuries!!!
