Continuity 600.0  0.1  0.8% + 5 0.8% + 5 0.8% + 5 0.8% + 5 95 A 1.4 V
Notes for continuity specifications:
1 Overload protection: 600 Vrms for short circuits with <0.1 A current
2 Built-in buzzer beeps continuously when the resistance measured is less than 30 . Resistance measurements above 
200  are considered open. For resistance measured between 30  and 200  (30   reading  200 ), the built-in
buzzer may beep depending on the device-under-test.
3 Continuity indicator: 2.7 kHz tone buzzer
Diode 1.500 V 0.001 V 1.0% + 3 1.0% + 3 1.0% + 3 1.0% + 3 0.3 mA 1.8 V
Notes for diode specifications:
1 Overload protection: 600 Vrms for short circuits with <0.4 mA current
2 Built-in buzzer beeps continuously when the voltage measured is less than 100 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).

Notes for DC current specifications:
1 60 A to 600 A ranges are for current clamp measurements.
2 60 µA to 600 µA ranges are for digital multimeter measurements.
3 Overload protection for 60 A to 600 A range: 600 Arms
4 Input impedance for 60 µA to 600 µA range: 4.2 k
5 Position error: 1% from reading
6 The accuracy is specified after the Null function is used to subtract the test lead resistance and thermal effect (by shorting
the test leads).
