If the previously set duration time is too long for the current battery charge, the longest calculated duration time possible for this battery charge appears instead. This is also indicated with the text 'MAX'. The duration of the measurement can be set from 15 minutes to 7 days. The batteries last for 7 days during data collecting provided that they are of the same type as those delivered with the indicator. The duration time can be selected in steps according to the following: · · · · 15 min; 30 min 1 - 6 h: each pressing = 1 h 12 h 1 - 7 d: each pressing = 1 d If the duration selected is too long for the current battery charge, the text 'BAT' appears.
