OPERATION

Battery diagnosis procedure
Refer to the instruction manual of the Portable Battery
Checker for detail. Connect the battery cartridge / porta-
ble power pack to this adapter instead.

nosing does not start.
How to interpret the diagnosis
results
► Fig.11
The diagnosis results are displayed on 6 separate
screens. Select the screen by operating the forward and
backward buttons.
► Fig.12
1) Number of charging times
The number of times a battery has been charged to
date is displayed on this screen.
2) Remaining capacity
The remaining capacity of the battery is indicated using
a bar graph display. When the bar extends up to the far
right end, it means that the battery is fully charged.
NOTE: This is not an indication of the service life of
the battery itself.
NOTE: The display may not be the same as the
remaining capacity indicator on the battery.
► Fig.13
1) Battery service life
The remaining service life of the battery is displayed
on this screen. When the battery is new, the bar graph
units are filled in up to the far right end, but they dimin-
ish in range as the battery deteriorates.
2) Battery temperature
The battery temperature is displayed in Celsius and
Fahrenheit temperature scale.
► Fig.14
1) Battery voltage
The voltage value of the battery is displayed on this
screen.
2) Voltage of each battery block (cell)
The voltage of each block inside the battery is displayed
using a graph. The number of block varies depending
on the battery to be diagnosed. A low voltage of a par-
ticular block or variations of three or more scale units
between blocks may indicate a problem in the cells
concerned or in the circuitry.
