Temperature Compensation
As the ambient temperature of a battery drops (or rises) the voltage required to maintain full
charge increases (or decreases). Temperature Compensation automatically varies the float
voltage to cancel the effects of changing temperature.
Enable Temperature Compensation for optimum battery life and battery capacity over a wider
temperature range.
Temperature Compensation does
NOT
function during a Battery Test.
► To enable Temperature Compensation
Use the SC100 keypad to go to:
Menu > Configuration > Temp Compensation > Edit
.
Or, in DCTools go to:
Control Processes >
Temperature Compensation
.
