b) Charging Batteries ("CHARGE")

The charging current to be set depends on the battery capacity and is usually 0.1C (also see chapter 7). High-quality

lead batteries also can stand a charging current up to 0.4C. However, you should always observe the battery manu-

facturer's instructions.

The value "0.1C" means that the charging current is equivalent to one-tenth of the rechargeable battery's

capacity. For a lead battery with a capacity of 5000 mAh (= 5 Ah) the charging current at 0.1C must be set

to 0.5 A.

Proceed as follows to charge a lead battery:

• First select the rechargeable battery type in the main menu, as described in chapter 12. a) ("Pb").

• Select the cell number in "CELLS" with the buttons "-" and "+".

• Push the button ">" in "MODE" repeatedly until the mode

"CHARGE" is displayed.

• For "CURRENT", use the buttons "-" and "+" to set the charge

current. Keep the respective button pressed for quick adjust-

ment.

• Another input window appears when you push the button

"MORE".

For "CHARGE", a maximum cell voltage can be set when charg-

ing.

For "DISCHARGE", you can set the minimum cell voltage when

discharging.

• If you push the button "START" for the duration of 3 seconds,

the charger will review the connected rechargeable battery (the

display will show "CHECK BATTERY.....").

Charging starts when everything is OK.

If errors are found (e.g. if no rechargeable battery is connect-

ed), the corresponding message will be displayed. The button

"BACK" will return you to the previous menu in that case.

• When charging is complete, the charger will emit a sound and a corresponding message will be displayed. The

button "STOP" will take you back to the setting menu.
