Notes for resistance specifications:
1 Overload protection: 1000 Vrms for short circuits with <0.3 A current.
2 Maximum open voltage is <+3.3 V
3 Built-in buzzer beeps when the resistance measured is less than 25 Ω ± 10 Ω. The multimeter can capture intermittent
measurements longer than 1 ms.
4 The accuracy of the 30 Ω to 3 kΩ range is specified after the Null function is used to subtract the test lead resistance and
thermal effect (by shorting the test leads).
5 For the ranges of 30 MΩ and 100 MΩ, the RH is specified for <60%.
6 The temperature coefficient of the 100 MΩ and 300 MΩ range is 0.1 × (specified accuracy)/°C (from –20 °C to 18 °C or
28 °C to 55 °C)
7 The accuracy for ranges <50 nS is specified after the Null function is used on an open test lead.
