消除低位準量測的不確定性

Keysight 34420A 奈伏/微歐姆錶是專為執行低位準量測而最佳化的高靈敏度萬用電錶。 數位歐姆錶結合了低雜訊電壓、電阻與溫度量測功能。 它已成為新的低位準量測靈活性和效能標準,為您提供可信賴、準確,且可重複的量測結果。

  • 在 100 pico-volt 和 100 nano-ohm 下進行高靈敏度的直流電壓和電阻量測
  • 使用標準的鉑阻溫度計(SPRT)探棒,以 0.003 ˚C 的準確度進行準確的溫度量測
  • 內建低雜訊雙通道掃描器,可簡化電壓比較
  • 隨附 BenchVue 軟體授權,讓您能更輕鬆地連接、控制儀器,並自動建立測試序列

Built-In Resistance and Temperature

The 34420A 7.5-digit multimeter combines low-noise, nano-Volt input circuits with a high-stability current source for precise low-level resistance measurements. This reduces the cost and complexity of using an external current source. It includes three resistance modes:

  • standard
  • low-power
  • voltage-limited for dry-circuit testing

Offset compensation minimizes thermal electromotive forces (EMFs) and associated errors.
