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” |
| Working temperature | 0-40°C,20%-90% RH(Non Condensing) |
| Storage temperature | -20°C-65°C,10%-95% RH(Non Condensing) |
| Acessories | 1 x loader,1 x adapter ,1 x battery holder 1 x connecting wire of battery holder,1 x resistance testing wire, 1 x load connecting wire |
