This tester fully meets my expectations. Throughout the budget there are which can all be read with the examiner a lot of batteries. There is almost no battery type (Battery) which is not detected by the auditor. Especially my AAA and AA batteries for my flash units will always be OK now. This was also the main reason for the investment in the device. I especially appreciate that you can also check button cells of any kind so ... on the one forgets so often (Power for date, time, storing the basic settings) usually pasiert the then on vacation and that's annoying. The auditor is to verify these Knopzellen 1x year no problem. I am very satisfied with the device and would recommend it unreservedly.
