Best Clamp Meter Buyer,s Guide

If you still not clear to choose that which clamp on digital multimeter can complete your needs perfectly. Don,t worry we will guide you completely about clamp on meters in this buyer guide, your confusions will end here. Selection of electric tools like clamp and multimeters is a sensitive matter and it demands time and research of various products.

Current clamp meters are basicaly same as general digital multimeters with higher current testing capacity additionaly. We can say that clamps are advance form of multimeters except in some cases where clamp meters are designed specifically to current testing approach. Where DMM comes with wide range of electronics features like capacitance , frequency , duty cycles, resistance and other functions some clamp meters may lacks one or more basic parameter.

First of all you should focus on features and functions of clamp meter, it should fulfil your job,s demand. For example many clamp meters comes with ac current capacity only, so if you has to work on dc circuits also then you should buy a meter with both ac and dc current test facility.

Following are some important points to consider before taking any decision.

  • It should have true rms technology for better accuracy on all types of loads.
  • Low impedance mode (Loz) is another vital feature which eliminates ghost voltage and may effect results.
  • Just as common saying “safety comes first” a best clamp meter should be rated for CAT 2,3 and 4 installations. It should hav eoverload protections on all ranges.
  • It,s ok if are good at manual range, otherwise go for auto range clamp meter as they can save time and easy to understand.
  • Clamp size is a major point to keep in mind while going for best product, clamp size determine rating or ability of clamp meter to read current.
  • Make sure with ac meter also can measure dc current if you needs to check dc currents regularly.
  • Clamp meter,s built material is a worthy factor for durability and survival in rough tough environments.
  • Display should be wide and clear from all viewing angles. Backlight is a must thing for lcds to work in low light areas.
  • Memory record is so beneficial for making comparison of signal behavior, mostly multimeters comes with Min/max and peak records.
  • A good clamp meter with low quality battery can annoy you more then a cheap multimeter. So never compromise on battery grade and also notice that clamp meter,s battery compartment should be easily accessible with easy battery replacement procedure.
  • Almost all companies give warranty on their poducts but only few done it in better way with live support and replacement procedures. Clamp meter should come with convenient warranty policy.

Types of clamp meters

There are basically two types of clamp meters,

Ct clamp meters

This type of clamp meters have current transformers within them for measuring ac current in amps.

Hall effect clamp meters

This type of meter has ability to detect both ac and dc amps.
