The DVI emit an audible alarm when voltage above 100VAC is detected. They are very easy to use as there are no range selector switches or settings to be made – just contact the conductor and read the display
The DVI-500 is designed to be used on both transmission and distribution systems in overhead and underground applications. The DVI-500 indicates voltage from 0.1kV – 500kV and is auto-ranging with no range selector switch or settings required.Voltage is displayed on a large 1.45”LED display with a 3-digit readout. In addition, an audible alarm alerts the user to the presence of voltage above 100VAC. The DVI is auto shut-off and will turn off after 4 minutes of inactivity.
Two overhead probes are supplied with the DVI-500 - a large 6”overhead hook probe for transmission system use (HP-DVI-6) and a smaller 2”overhead hook probe for distribution system use (HP-DVI-2). Simply attach the correct probe for the proper overhead application. Use of a hotstick isrequired for all overhead and underground applications.

HD Electric DVI-500/K01 数字电压指示器套件 (500kV)
当检测到电压高于 100VAC 时，DVI 会发出声音警报。它们非常易于使用，因为无需进行范围选择器开关或设置——只需接触导体并读取显示
DVI-500 设计用于架空和地下应用中的传输和分配系统。 DVI-500 可指示 0.1kV – 500kV 的电压，并且无需量程选择器开关或设置即可自动调整量程。电压显示在 1.45 英寸 LED 显示屏上，带有 3 位读数。此外，当电压高于 100VAC 时，会发出声音警报提醒用户。 DVI 是自动关闭的，将在 4 分钟不活动后关闭。
DVI-500 随附两个架空探头 - 一个用于传输系统的大型 6" 架空钩形探头 (HP-DVI-6) 和一个用于分配系统的较小的 2" 架空钩形探头 (HP-DVI-2)。只需为适当的高架应用连接正确的探头。所有架空和地下应用都需要使用热棒。
