IEC 61243-3:20 09适用于手持式两极电压检测仪及其附件（鳄鱼夹和可拆卸引线），用于与电气系统部件接触: -用于交流。额定频率在16 2/3赫兹至500赫兹之间时，电压不超过1 000伏，和/或 -为了华盛顿。电压不超过1 500 V。 本标准涵盖的电压检测器旨在室内和室外的干燥和潮湿条件下使用。它们不打算在下雨的情况下使用。本标准涵盖的电压检测器不打算用于连续操作。本标准涵盖的电压探测器旨在用于海拔2 000 m以上的地方。本标准涵盖的电压检测器不被视为测量设备。测量装置的相关安全要求包含在IEC 61010系列中。这第二版取消并取代了1998年出版的第一版。这是一次技术修订。

IEC 61243-3:2009 is applicable to hand-held two-pole voltage detectors with its accessories (crocodile clips and detachable leads) to be used in contact with parts of electrical systems:
- for a.c. voltages not exceeding 1 000 V at nominal frequencies between 16 2/3 Hz and up to 500 Hz, and/or
- for d.c. voltages not exceeding 1 500 V.
Voltage detectors covered by this standard are intended to be used under dry and humid conditions, both indoor and outdoor. They are not intended to be used under rain conditions. Voltage detectors covered by this standard are not intended to be used for continuous operation. Voltage detectors covered by this standard are intended to be used up to 2 000 m above sea level. Voltage detectors covered by this standard are not considered as measuring devices. Relevant safety requirements for measuring devices are included in IEC 61010 series. This second edition cancels and replaces the first edition published in 1998. It is a technical revision.
