PLUS Safety and operational considerations Notes a The charger in the instrument is a pack cell charger This means that the battery cells are connected in series during the charging The battery cells have to be equivalent same charge condition same type and age a One different battery cell can cause an improper charging and incorrect discharging during normal usage of the entire battery pack it results in heating of the battery pack significantly decreased operation time reversed polarity of defective cell a If no improvement is achieved after several charge discharge cycles then each battery cell should be checked by comparing battery voltages testing them in a cell charger etc It is very likely that only some of the battery cells are deteriorated a The effects described above should not be mixed with normal decrease of battery capacity over time Battery also loses some capacity when it is repeatedly charged discharged Actual decreasing of capacity versus number of charging cycles depends on battery type It is provided in the technical specification from battery manufacturer 2 3 Standards applied The PolarityPLUS instrument is manufactured and tested in accordance with the following regulations Electromagnetic compatibility EMC IEC 61326 Electrical equipment for measurement control and laboratory use EMC requirements Class B Hand held equipment used in controlled EM environments Safety LVD
