Page 5: Introduction
Therefore, the dependence between test pulse form and value and battery answer form and value could be slightly different. That is why Qulon-12m is not a high precision device for capacity measurement. It estimates battery capacity basing on electrical measurement and... -
Page 6: Safety Precautions
If summary voltage exceeds 400 volts device could be damaged. Qulon-12m is a complicated device. Do not try to dis- assemble it. There are parts that need service inside. The device should be repaired only by certified personal. -
Page 7: General Description
Attention! Do not use device with back lid opened. 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 volt- age and additional information: adjustment coefficient, num- ber of recorded measurements and current croup of records. -
Page 8: Battery Capacity Estimation
3. Battery capacity estimation 3.1. What is battery capacity Battery capacity is an electrical charge (quantity of electricity) that battery can deliver under specified conditions. Usually battery capacity is expressed in ampere-hours (A*h or Ah). Capacity equals to discharge current (in amperes) multi- plied by discharge time (in hours). -

If battery terminals are dirty or oxidized – clean them. 3.2.3. Connection to a battery Battery capacity indicator Qulon-12m is supplied with special test cables that use four-wire (Kelvin) connection to a battery. Two halves of one (red or black) clamps are insulated from each other. -
Page 12: Battery State Of Charge
3.2.4. Battery state of charge Qulon-12m estimates capacity for fully charged bat- teries only. The battery under test should have voltage not less then 12.6 V. If a battery is deeply discharged (voltage less the 9 V) -

-12- If a battery is not fully charged (voltage is more then 9 V and less then 12.6 V), device shows a message “Voltage low” and battery voltage at the screen. In this case, discon- nect clamps from the battery and charge the battery in full according to the battery manual. -
Page 14: Qulon's Screen During Battery Capacity Estimation13
If battery capacity estimation was successful, the ca- pacity value is shown on the screen. This result can be saved in memory. Qulon-12m has two saving regimes (save modes): saving by default (result is saved immediately after it appears) and saving by command (one needs to push button for saving). - Page 15 -14- Battery capacity – measured in ampere-hours.

-17- 5. Memory 5.1. Memory organisation Battery capacity indicator Qulon-12m has memory for 200 test results. For user’s convenience, test results can be split to groups. Maximum number of groups is 26, each group is identified with a letter of Latin alphabet – from A to Z. A user arbitrarily manages the quantity of results inside group. -
Page 19: Two Save Modes
All memory operations are made with the help of main menu. 5.2. Two save modes Qulon-12m has two save modes: “save by default” and “save by command”. Under “save by default” mode just received test result is saved automatically. It can be erased by pressing lower button. -

-19- In “A” case (see above), the following information is saved: estimated capacity, calibration coefficient (for current test), battery voltage, group name and number inside group. In “B” case, the appropriate message is saved instead of estimated capacity. If there are 200 test results saved in memory, a mes- sage “memory full”... -
