Capacity Test Using A Fixed Resistor
In this mode the discharge current will fall as the battery voltage falls. It will discharge
the battery at the current which is calculated continuously from the fixed resistor value
entered and the battery voltage until the set time has elapsed. If the battery target
voltage has not been reached the unit will stop and report a capacity test of 100%. This
reported capacity is the minimum capacity of the battery. If the battery target voltage is
reached before the set time the unit will stop and report the capacity calculated as
follows: -
The parameters required for this mode are as follows: -
Target Volts :
This is the point at which the discharge will stop.
Fixed Resistor Value :
This is the resistance value of the emulated fixed resistor to
be used.
Test Time :
This is the maximum time at which the discharge test is to be performed.
This is usually 1 Hour.
