6.2 Discharge
Standard Discharge Routine
The Discharge routine will discharge a battery down to the Voltage Cutoff value specified in Quick Setup or Profile Setup. The output delivered will be measured in mAH, or AH and WH. A rating of Percent Capacity will also be calculated for the battery. This rating will be based on the actual AH output delivered expressed as a percentage of the rated capacity. Be sure to specify the Rated Capacity in order for this rating to be representative. By specifying a pass threshold a Pass or Fail text message will also be calculated at the end of the discharge session. This text message will appear in the Results Data when the discharge session terminates.
Memo: Universal Discharge Function. Connect battery to begin session. Battery will discharge down to lower cut-off voltage specified. Flashing yellow LED indicates the test is proceeding. Solid green LED indicates output exceeded pass threshold. Solid yellow LED indicates battery failed to deliver the pass value.
Pulse Discharge Option
A two part discharge pulse can be specified rather than a constant current discharge.
To implement this feature set the Discharge Current = 0 and specify the pulse requirements. There are four fields used to define a two part pulse. Specify the Current and Duration for each part. The two parts of the pulse will repeat continuously for the duration of the discharge step. In the example above, the battery will discharge at 50mA with a 750mA pulse for 250mS every 10 seconds.
For a more complex pulse, a custom routine can be programmed. Custom routines can define a pulse with up to 6 parts. See Program Pulsing for more information.
When the pulsing feature is not being used, set all four pulse fields = 0 and specify a constant current discharge using Discharge Current.
