Overload protection:

For UT51:

2A, 250V fast acting fuse, φ5x20mm(below 2A

range)

10A, 250V fast acting fuse,φ5x20mm(at 10A range) .

For UT52/53/54/55:

315mA, 250V fast acting fuse,φ5x20mm (No fuse

at 20A range).

Max current input :

For UT51: 10A (The measurement time for high

current should be less than 10 seconds maximum,

and the interval time between two measurements

should be greater than 15 minutes.

For UT52/53/54/55: 20A (The measurement time

for high current should be less than 15 seconds

maximum, and the interval time between two

measurements should be greater than 15 minutes.

Measuring voltage drop: Full range is 200mV.

Display: Average Value (RMS of Sine Wave ) .
