Formal operation of the meter before you read the description of this process:
1.The instrument mainly divided into "execution parameters browse screen" and
"factory-set parameters" of two parts。
2.Please do not suggest any non-engineering personnel to enter and modify the
"factory-set parameters" inside the content, so as to avoid system anomalies
caused by improperly set or damaged.。
3.After the new meter purchase process engineers Please read this note, based
on their needs, set the appropriate parameters to fully understand these
processes can contribute to the later of the operating
