EN 61010-2-032
CAT III 600V
Pollution Degree 2
Overvoltage Category I (CAT I):
Equipment for connection to circuits in which measures are
taken to limit the transient overvoltages to an appropriate low level.
Overvoltage Category II (CAT II):
Energy-consuming equipment to be supplied from the fixed
installation.
Overvoltage Category III (CAT III):
Equipment in fixed installations.
SAFETY INFORMATION: (Read First Before Operation)
Please follow the following instructions carefully for safe operation.
■NEVER use the clamp meter for Voltages higher than 600V.
■DO NOT hold the clamp meter beyond its tactile barrier.
■DO NOT use the clamp meter and accessories if they look
damaged.
■USE CAUTION when working with high voltages.
■USE CAUTION when measuring the voltages higher than
30VAC rms or 60VDC. These voltages pose a shock hazard.
■USE EXTREME CAUTION when working around bare
conductors or bus bars.
■ALWAYS use the clamp meter as the instructions in the manual.
WARNING: If the flexible tester is used in a manner
Not specified by the manufacturer, the protection
Provided by the clamp meter may be impaired.
