If SD card just the first time use into the meter, it recommend to make the «SD card Format» at first.

c. Time setting

If the meter is used at first time, it should to adjust the clock time exactly.

d. Decimal format setting

The numerical data structure of SD card is default used the «.» as the decimal, for example «20.6» «1000.53». But

in certain countries (Europe ...) is used the «,» as the decimal point, for example «20, 6» «1000,53». Under such

situation, it should change the Decimal character at first, details of setting the Decimal point.
