Overload protection: 1000 Vrms. For millivolt measurements, 1000 Vrms for short circuits with <0.3 A current.
Input impedance: 10 MΩ (nominal) in parallel with <100 pF.
For 20 to 100 kHz accuracy: Three counts of the LSD per kHz of additional error is to be added for frequencies >20 kHz and signal inputs <10%
of range.
Overload protection for 300 μA to 300 mA range: 0.44 A/1000 V; 10 × 35 mm 30 kA fast-acting fuse
Overload protection for 3 A to 10 A range: 11 A/1000 V; 10 × 38 mm 30 kA fast-acting fuse
Specification for 300 mA range: 440 mA continuous.
Specification for 10 A range: 10 A continuous. Add 0.3% to the specified accuracy when measuring signals >10 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.
