Specification:

Model	RFNT4
Size	201 x 99 x 35 mm
Weight	383g
Adapter	Input 100~240V Output 24V/3A
Display mode	Segment LCD with white backlight + LED in red and green
Discharge mode	Constant current discharge,system support 1000mA Max, can set by DIS.CHG. External load, Max discharge current add to 4A
Charge mode	Constant current and constant voltages are the main mode. Active charge and pre-charge are available according to different battery voltage.
Active charge	Tester may not recognize 0V-battery. Users should press the charge key to start up the active charge function. Being activated and going to normal charging status, when the battery establishes communication with the tester.
Pre-charge	Battery goes into pre-charge status when voltage of battery under setting pre-charge voltage. Constant current charge Battery goes into fast charge status when voltage of battery over setting pre-charge voltage. Fast charge time relates to the battery design capacity and fast charge current.
Constant voltage charge	Battery goes into constant voltage charge, when battery voltage up to battery saturation voltage, now current will be decreasing by battery saturation voltage
End of charge	When the current reduced to terminate current, Or e capacity reaches 100% Charge current 3000mA Max, set by CHARGE function Battery testing Testing battery charge and discharge function is good or bad,test time set by user, according to user demand, can set by BT.TEST item. Test passed will display “OK” otherwise display “NG”
