直接測量或HV-SMARTPROBE™，您的選擇
Vitrek的4700型可直接精密測量峰值高達15KV的電壓，開箱即用，無外部探頭。對于90%的耐壓測試器和其他高壓源而言，已經足夠；但是，如需擴大高壓測量范圍，只需增加一個或多個可選用的35KV、70KV和100KV HV-SmartProbes™。Vitrek HV-SmartProbes™可在插入4700型后下載得到的自身校準數據并存儲，從而得到高精準的校準后讀數，而且使任何Vitrek HV-SmartProbe™都能與任何4700型高壓計配合使用。
HV-SmartProbe’s™*的超低TC衰減器設計移除了電壓系數加法器的使用，同時，其降低電容結構技術提高了AC性能。除直接輸入端子外，4700型還有兩個探頭輸入 - 一個用于擴大測量范圍的探頭或兩個進行高壓差分測量的探頭。
性能，設計體現
測量完整性是我們的要求 - 無論是制造高壓醫療成像設備的生產線、進行突破性研究的實驗室，或是認證測試設備的校準實驗室，都必須仔細挑選工具。為確保的測量精度，4700型每秒抽取40,000多個樣點，然后對這些樣點進行過濾、再抽樣、縮放和偏移校正，以提供高達每秒60個強化讀數 - 以上所有過程都采用了“*”數學算法。True RMS交流電讀數能被正確讀出，而DC測量則提供非常穩定的超快速處理。除此以外，4700型可提供低至0.01 Hz的VLF AC讀數，以及波動、峰間、波峰因數和基頻測量。
高壓測試自動化
憑借4700型內置的以太網端口、高速串行通信端口或可用的GPIB，可實現高壓測試要求的自動化。4700型可*編程，因此可以自行選擇測量模式和頻寬，然后根據需要的頻率讀取讀數。4700型標配有USB打印機端口，以獲取讀數和打印高壓圖，從而可以記錄下標準耐壓測試中的驟降或過沖。
