CC, CV, CR, CP, CV+CC, CR+CC
In addition to the basic test modes of CC, CV, CR, CP, the FT6800 series also has CV+CC and CR+CC compound mode to meet comprehensive test requirements. Users can set the current limit value according to their own test requirements to avoid overcurrent damage to the device under test.
Sequence
Sequence test is available in CC, CV, CR, CP mode. The user can edit a load test sequence. FT6800 series supports 20 sequence files, and each file with 50 steps. Single step time can be set to 0.1ms ~ 90,000s. Sequence files can be linked. Users can also set the number of cycles and switching mode of the sequence.
Battery test
The The FT6800 series load provides battery test functions, including battery internal resistance test and battery capacity test.
Battery internal resistance test
It uses DC discharge method (DCR).
Battery capacity test
It uses constant current for discharging.
During the process, the discharge time and AH/WH will be recorded.
Testing of super capacitor
OCP test
The FT6800 series provides OCP test within itself.
Users can utilize the PC software to perform OCP/OVP/OPP test so as to obtain V/I curve, and test the stability of the protection point.
External analog programming
Other devices can continuously control the load through an external voltage signal (DC or AC). The external voltage signal of 0～10V corresponds to 0～100% full-scale load current. This function is also suitable for various complex load waveforms test.
