直(zhi)流(liu)高壓測試儀產品特點：
1、精度高、測量準確。電壓、電流表均為數字顯示，電壓分辨率為0.1kV，電流分辨率為0.1uA，控制箱上電壓表直接顯示加在負載試品上的電壓值，使用時無需外加分壓器，接線簡單。儀器具有高、低壓端測量泄漏電流、
2、體積更小、重量更輕、更美觀、更可靠、操作簡便、功能齊全，便于野外使用
3、增設了高精度75%VDC-1mA的功能，做氧化鋅避雷器測量帶來極大的方便。輕輕一按無須計算。本儀器控制箱上有75%的電壓功能鍵，在做避雷器試驗時，當電流升到1000uA時、就打開0.75的按鈕，這時電壓表、電流表所顯示的值就是75%的數據，做完后應立即將升壓的旋鈕回到零位上，同時將細調電壓旋鈕回到零位上，并應立即按綠色按鈕，切斷高壓并關閉電源開關。再做其它的試驗
