Function
The accuracy of the 30 to 300 mV range is specified after the Null function is used to subtract the thermal effect (by shorting the test leads).
For Z
Overload protection: 1000 Vrms for short circuits with <0.3 A current.
Maximum open voltage is <+3.3 V
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.
The accuracy of the 300 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).
For the ranges of 30 MΩ and 100 MΩ, the RH is specified for <60%.
The accuracy for ranges <50 nS is specified after the Null function is used on an open test lead.
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)
