Function
Diode
Notes for diode specifications:
1 Overload protection: 1000 V
2 Built-in buzzer beeps continuously when the voltage measured is less than 50 mV and beeps once for forward-biased
diode or semiconductor junctions measured between 0.3 V and 0.8 V (0.3 V ≤ reading ≤ 0.8 V).
3 Open voltage for diode: <+3.3 V
4 Open voltage for Auto-diode: <+2.5 V

Notes for DC current specifications:
1 Overload protection for 300 μA to 300 mA range: 0.44 A/1000 V; 10 × 35 mm fast-acting fuse
2 Overload protection for 3 A to 10 A range: 11 A/1000 V; 10 × 38 mm fast-acting fuse
3 Specification for 300 mA range: 440 mA continuous
4 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.
