battery tests;
B) "main sounds" - audio signals will accompany only in 
case if some message arrives;
C) "no sounds" - the buzzer is completely disabled.

Exit this menu by pressing the top button or un-

plugging the device from the battery.

6.5. Language

Qulon can issue messages using two languages: 

(e.g. Russian or English). Consult your dealer concern-
ing your particular version.

To change message language enter main menu, 

choose item options, choose item language. Now you 
see the current language. Choose desired language by 
pressing lower button.

To exit menu disconnect Qulon from the battery.

7. Replacing clock battery

The   internal   clock   is  powered   by   a   lithium 

battery, fixed in a holder under a sliding cover on the 
rear panel. Estimated battery life - at least one year.  If 
date or time information is correct – it may be because 
of the discharged battery. In this case the battery must 
be replaced. 

Do not  leave empty battery in the device.  The 

absence of  a  battery  in a device affects only the clock 
malfunction, all other functions work as usual.

To replace the internal battery unplug Qulon 

-32-

from the battery under test,  open the sliding cover on 
the rear panel and remove the battery from the holder. 
After this, insert the new battery into the holder with plus 
terminal up and close the rear lid.

Observe polarity when replacing battery.

Operation   of   the   device   with   the   open   rear 

cover is not allowed.

Connect the device to  a  battery  or adapter  and 

set the time and date in accordance with section 6.4 of 
this manual.

Please use only the correct size lithium batteries 

CR2032 (diameter 20 mm, thickness 3.2 mm). Do not 
attempt   to   charge   the   empty   battery   (they   are   not 
designed for this purpose).

Do   not   replace   the   lithium   battery   with   other 

sources of power!

8. Calibrating Qulon (how to 

determine right coefficient value)

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  perform  the  recalibration by changing 

the calibration coefficient.

Qulon-12ns   calculates   the   estimated  battery
