Overvoltage Category I (CAT I):
Equipment for connection to circuits in which measures are taken to limit the transient
overvoltage’s 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.

III.2 Measurement of RMS value, THD-F and Harmonics of ACV
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.

III.4 Waveforms of ACV and ACA with Phase Angle (φ)
When users set the rotary switch at waveform position, the unit will display both voltage and current waveform
with phase angle.
