Warning: This instrument is only allowed to be used in the specified measurement class. Measurement class definitionSafety requirement CN ⚫ Class I refers to measurements taken on a circuit not directly connected to the main power supply. For example, measurements made on circuits that are not exported from a main power supply, especially from a protected (internal) main power supply. In the latter case, the instantaneous stress will change. Therefore, the user should understand the instantaneous capacity of the instrument. ⚫ Class II refers to measurements taken on a circuit directly connected to lowvoltage instruments. For example, measurements made on household appliances, portable tools, and similar equipment.
