Notes for DC current specifications:

1 Overload protection for 60 μA to 600 μA range: 600 Vrms for short circuits with <0.3 A current.

2 Overload protection for 6 A to 10 A range: 11 A/1000 V; 10 × 38 mm fast-acting fuse.

3 Specification for 10 A range: 10 A continuous. Add 0.3% to the specified accuracy when measuring signals >10 A to 20 A

for 30 seconds maximum. After measuring currents >10 A, cool down the multimeter for twice the duration of the

measured time before proceeding with low current measurements.

4 DC current range of 0.6 mA to 1 mA is not measureable on the U1232A and U1233A models.
