1. Notes for voltage specifications:
• 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_LOW measurements, autoranging is disabled and the multimeter’s range is set to 1000 volts in the manual ranging mode.
2. Notes for resistance specifications:
• 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)
