The screen displays the current state of charging. Press Batt
type/Stop to stop the process.
The audible beep indicates you the end of charging process.
7.2 Discharging NiCd/NiMH battery
Set discharge current on the left side and nominal voltage on
the right. The discharge current ranges from 0.1 to 1.0A, and
the nominal voltage ranges from 0.1 to 25.0V. Press Start
/Enter for 3 seconds to start the discharging process.
The screen displays the current state of discharge current.
You can press Start/Enter to change and store the discharge
current in the process.
Press Batt type/Stop to stop the process. The audible beep
indicates you the end of charging process.
7.3 NiMH /NiCd battery charge and discharge mode cycle.
Set the sequence on the left and the number of cycle on the
right. You can use this function to balance and refresh battery.
To avoid temperature rising of the battery, there will a brief
cooling process after each charge and discharge cycle.
Cooling time range: 0—60 minutes.
You press Start/Enter to change the charge or discharge
current in the process. The audible beep indicates you the
end of process.
At the end of the process, it will show you the capacities of
each cyclic process.
Press INC or DEC, the screen will show the result of each
cycle in order.
8. Pb( lead-sulphuric acid) battery program
This is designed for charging Pb( lead-sulphuric acid) battery with nominal voltage from 2 to
20V. Pb batteries are totally different from NiCd or NiMH batteries. Since the capacity of Pb
battery is lower than NiCd or NiMH batteries', they can only deliver lower current compared
with NiCd or NiMH batteries and have current limits when charging. Pb battery's current is
1/10 of its capacity. And fast charging is not allowed, you have to operate it according to the
instruction of the manufacturer.
The screen turns bright when press Start/Enter, then you can press DEC/INC to change
the parameter value, press Start/Enter to store
