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):

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.

Voltage:

a. Set the rotary switch at V position.
b. Insert the test leads into the input jack. Connect the test prods of the test

leads in PARALLEL to the circuit to be measured.

NOTE: If the peak value of the input AC voltage is greater than the maximum
value of the range, then symbol of OL will be displayed.
