basing on electrical measurement and some algorithm
saved in Qulon’s microprocessor.
Qulon-12ns is calibrated on factory. Using this
calibration, you can estimate the capacity of any 12-volt
lead acid battery. Experienced user can reduce capacity
estimation error by device recalibration basing on the
battery with known capacity.
1. Safety precautions
Unpack Qulon-12ns and check if there are any
transport damages. If any, appeal to your dealer or the
transport company.
Attention!
Lead acid battery under test is a
source of possible danger. Battery terminals shorted
with any metal detail could cause burn or fire. Please
adhere to battery maintenance and service rules.
If battery under test is a part of high voltage bat-
tery system and battery test is conducted without bat-
tery disassembly be especially careful. Do not connect
test clamps to several 12-volt batteries connected in
series. If such case, device will not switch on. If sum-
mary voltage exceeds 400 volts device could be dam-
aged.
Qulon-12ns is a complicated device. Do not try
to disassemble it. There are no parts that need service
inside. The device should be repaired only by certified
personal.
Attention!
Do not use device with back lid
opened.

Attention!
When using Qulon without discon-
nection batteries from the charger (rectifier) observe
safety rules for working with electric facilities.
2. General description
There is a LCD display in the center of Qulon’s
front panel. It is used to show ampere-hour capacity,
battery voltage and additional information: adjustment
coefficient, number of recorded measurements and cur-
rent croup of records. Qulon has memory for recording
results of battery tests. The maximum number of recor-
ded results is 200. User is free to separate recorded
results to as many as 26 groups.
If it is impossible to estimate battery capacity be-
cause of some reasons, alarms are shown at the dis-
play.
There are two control buttons on the front panel
to the left of display.
Right panel of Qulon is the place for test cable
connector. Qulon is supplied with special test cables
that use four-wire (Kelvin) connection. This type of con-
nection is used in order to diminish contact resistance
influence on the device results.
There is a lithium battery providing energy to the
internal clock under the sliding cover on the rear panel
of the device.
