Scaled C-code
Due to the power limitations on the analyzer, if a C-code requires a higher charge
or discharge rate than the analyzer is capable, it automatically scales the C-code.
An inverse S on the top-right hand corner of LCD screen when the basic C-code is
displayed will indicate a scaled C-code.
C-code Matrix
When a C-code matrix has been stored to perform a QuickTest, an inverse T in the
top-right-hand corner of the LCD screen will display along with the basic C-code.
Locked C-code
Cadex locks some C-codes at the request of the battery manufacturer. An inverse
L on the top-right hand corner of the basic C-code display indicates a locked C-
code. These C-codes cannot be edited but they can be deleted.
Extended C-code Parameters
In general, extended C-code parameters can be left on their default settings. For
servicing intrinsically safe (I/S) batteries or Hawker SLA batteries, pay close
attention to the extended C-code parameter settings (see
Extended C-code
Settings for Special cases
, page 57).
Charge Rate
A battery with 1000mAh capacity that is charged at 500mA has a charge rate of
0.50C (where C stands for capacity). A lower charge rate reduces the charge
current and increases service time. Maximum current is 4000mA (6000mA for the
C700ER) for batteries with a stated cell voltage of up to 7.2 V. Maximum current is
reduced for batteries with higher nominal voltage. For example, on the C7200, the
charge rate for a 14.4V battery will be automatically scaled to 2000mA. An inverse
S (Scaled) will be displayed on the basic C-code screen.
