3.Besuretokeepthetestleadsoffthetestedpointwhenconvertingthefunctionand
range.
4. Selectthecorrectfunctionandrangetoavoidfaultoperation.Eventhoughtthis
instrumenthasthefullfunctionprotection, pleasepayyourcloseattention when measuring
foryoursafety.
5.Donotusethisinstrumenttomeasurebeforefixingthebatteryandtighteningthe
bottomcase.
6.DonotinputthevoltageattheCapacitanceandCurrentRange.
