The Diagnostic Charger, with a View
 
Diagnosing
l    Each charge cycle starts with diagnosing cells for a possible short / deep discharge condition, for bad contact
      
and leaking /dry cells
l     "Forming" attempts to restore deep discharged cells
l     Stained cells with bad or no contact are indicated as such
l     Dry cells are marked for disposal

Failed "Forming, "Dry Cell" and "Bad Contact" detection disable cells for further charging, rescue attempts
and results are shown in LCD

Charging
l    Slide switch permits to select from 3 different charge currents, for 4 cells AA/AAA: 1200/600mA, 900/400mA,
     700/250mA

l
     Batt.bars in LCD climb upwards, charged-in "Ah" values increase
l    Charge End: tot.AmpHours & charge time stay in LCD (toggling)

Discharging/Charging
l    Pressing "Discharge" key initiates discharge of cells
l    Batt.bars in LCD descend, discharged "Ah" values increase
l    End of Discharge: cells change into charge mode, discharged capacity stays in memory, ready
       to be recalled, at any time
l    End of Charge: the "Energy Index" concludes a completed charge/discharge cycle by assigning
       the healthiest cell the index "1.00" the reference for rating all other cells in decreasing order. Cells
       with index figures close to each other are matching in strength, those outside a narrow cluster
       should be discarded of

Cycling/Conditioning
Pressing "Discharge" key for several seconds triggers a continuous charge/discharge cycle which comes to
a halt only if no further increase of capacity is registered. New cells are mostly weak, cycling with small
charge current builds considerable strength

Capacity Recall
Pressing "Capacity recall" calls up last discharged AmpHours shown in LCD as "Ah" values.

Select-a-Cell
Repeated pressing of the "Cell select" button assigns temporary, independent control to one or more
charge bays. Any one of the targeted bays can be assigned a discharge or cycling job, regardless of the
status all other cell are in.

General
l     4 NiCd/NiMH batteries (AA or AAA)
l     Battery-full criteria: negative Delta-U detection with safety timer
l     4 indiv.temp.sensors prevent possible heating of cells
l
     Detachable universal mains adaptor and car plug for 12VDC
