scope:

In addition to the scope of IEC 61326-1, this part of IEC 61326 specifies more detailed test configurations, operational conditions and performance criteria for equipment which is: - used for testing, measuring or monitoring of protective measures in low-voltage distribution systems, and; - powered by battery and/or from the circuit measured, and - portable. Examples of such EUT include, but are not limited to, voltage detectors, multimeters, insulation testers, earth continuity testers, earth resistance testers, loop impedance testers, "residual-current-device-testers" (RCD-testers) and phase sequence testers as defined in IEC 61557. The manufacturer specifies the environment for which the product is intended to be used and/or select the appropriate test level specifications of IEC 61326-1.
