Digital AC Clamp Meter

What is Digital AC Clamp Meter / Clamp on meter ?

This instrument has been design for the main purpose is measuring the AC AMPERE .

I have one Digital AC Clamp Meter brand KYORITSU model KEW SNAP 2017.

The features :-

• Design to CAT.III 600 VAC and pollution degree 2 specified by the international safety standard IEC 61010-1
• Tear-drop-shaped jaw for ease of use in crowded cable area and others tight places.
• Data hold function
• Wide frequency range from 40 Hz to 1 kHz

Specification

• Effect of conductor position :
• 2017 Within 2% of indicated value at the center to a 10mm‐dia conductor carrying 100A, at every part inside the jaws.
• 2027 Within 3% of indicated value at the center to a 10mm‐dia conductor carrying 100A, at every part inside the jaws.

• Effect of external : 2 A or less in AC magnetic field of magnetic field 400A/m

• Dimensions : Approx. 91(W)×208(H)×40(D)mm

• Weight : Approx. 400g(batteries included)

• Safety Standard : EN61010-1 , EN61010-031 ,EN61010-2-032 (600V AC CAT. III Pollution degree2, indoor use) , EMC Standard : EN 55022

How to perform AC CURRENT MEASUREMENT?

• Set the range switch to 200A or 600 A
• Press the trigger to open transformer jaws and clamp onto the conductor.The mos accurate reading will be obtained by keeping the conductor at the center of the transformer jaws
• Read the value of AMPERE at display

WARNING!!!

• Keep your finger and hand behind the barrier during measurement.
• Do not make measurement with the battery cover removed from the instrument.
• Please be sure to remove a measurement code before measurement.
• Do not operate the switch range during a measurement
• Never use this instrument on a circuit above 600 VAC RMS

Digital clamp on meter is very useful measuring instrument when we perform electrical job or troubleshooting task.For detail how to use a clamp on meter,Please watch my technical VIDEO at my post  : HOW TO USE A CLAMP ON METER
