12. Explanation of the CC / CV charge process for Li batteries
The CC-CV charge process can be divided into three phases:
1. In the CC (Constant
Current) phase the
current is maintained
at a constant level
until the battery rea-
ches the final charge
voltage of 4.2 V / cell.
2. The next part of the
process is the CV
phase, in which the
voltage is maintained
at a constant level; at
this point the battery
is alreadsy about 85 -
90% full, and the
charge current is allo-
wed to decline.
3. At around 98% (=
0.05 of Charge current remaining) the cut-off melody sounds, and the termination dis-
play appears on the screen. At this point the battery is virtually fully charged, and can
be disconnected from the charger. However, if the battery is left connected to the
charger, the charge process continues with a minimal trickle current. Final termination
occurs when the residual current falls to around 30 - 40 mA.

13. EXPLANATION AND USE OF THE ZOOM FUNCTION

00:06:37 0.01A
6.939Vc 0.50Vr=A x1
The meaning of the numbers: x 1 = maximum overall display; x 5 = reduced to 1/5 size.
00:06:37 0.01A
6.939Vc 0.20Vr=A x3
The amplification of the vertical display Vr = M (zoom) can also be adjusted manually in
order to obtain a more accurate display when you wish to read off the values. If the reso-
lution is too high, the curve will extend beyond the screen window. The curve can now be
brought back to the centre of the screen by adjusting the centre voltage Vc; Vc is the cen-
tre voltage for the display window.

vertical axis, but the hori-
zontal axis can be scaled
manually by x 1 ... x 5.
