by cursor.
To exit menu – disconnect test clumps from the
battery terminals.
6.2. Save mode
When you enter this menu item you are offered
to choose one of two save modes: save by default or
save by command. Move cursor to the desired line.
Your adjustment is saved automatically. Now you can
go to the main menu by pressing top button or discon-
nect Qulon from the battery.
6.2.1. Save by default
If you choose this save mode Qulon will save the
test result automatically, right after the result is re-
ceived. Screen view for this save mode is shown in fig-
ure 2. If you do want to hold just saved result press
lower button – you will have 3 possibilities:
a) to delete the just made estimation from the
memory and repeat the test automatically;
b) to delete the just made estimation from the
memory without repetition;
c) to return to the last screen (fig. 2).
6.2.3. Save by command
If you choose this save mode Qulon will not save the
test result automatically. Screen view for this save
mode is shown in figure 3. If you need to save just

received result – press the lower button. You will be
asked for confirmation to save the result to a designated
group and battery number inside group. You will have 3
possibilities:
a) to save the just made estimation to the
memory (group name and the battery number is
shown);
b) to return to the last screen (fig. 3);
c) to initiate the test repetition.
6.3. Calibrate (coefficient adjustment)
Warning! Lead acid battery capacity indicator
Qulon-12ns is a complicated device. Therefore, its re-
calibration should be made by the qualified user who
studied the present manual and who distinctly under-
stands the sequence and probable results of the action.
Qulon-12ns is calibrated at the factory with the
use of average characteristics of 12-volt lead acid bat-
teries. Some specific battery may need some other cal-
ibration. To diminish capacity estimation error user can
recalibrate device for testing of some specific battery
type or confirm the validity of factory calibration.
User can do Qulon-12ns recalibration by chan-
ging the calibration coefficient.
Qulon-12ns calculates the estimated battery ca-
pacity according the following formula:
Е = Е
о
* К,
where: Е
о
– estimated capacity without user’s correc-
tions, К – calibration coefficient.
