Protection
Fuse protection for 500uA, 5mA, 50mA, 500mA and 2A
ranges. To obtain accurate measurement results, please
refrain from using the 20A terminal for more than 15
seconds when measuring high current.
When the input exceeds the full scale of the selected range, the display will
indicate over-range: “—OL—“.
TRUE RMS AC OR AC+DC CURRENT
Accuracy
Between 2% of range and full range.
