When troubleshooting, the right tool will build the distinction between fast answer and
awkward frustration. There are two diagnostic tools have many options that sound similar.
The digital multimeter and also the clamp meter. However, these two tools have their
individual blessings, associate degreed one is certainly is unquestionably higher for
troubleshooting certain issues than the opposite Clamp-on meter or just ‘clamp meter’
is an instrument that's wont to live this flowing through a conductor. Associate degree
AC Clamp meter essentially consists of a current electrical device in its jaws, bar CT
sometimes. Utilizing the principle of current electrical device, the reading is displayed.
Whereas a DC clamp meter is kind of completely different. It uses a Hall result of the
sensing element for measure this.
How does AC clamp meter work?
When the instrument is ‘clamped’ on a conductor, the conductor itself acts
as primary and also the magnetic flux thanks to current flowing through the
conductor cuts the secondary of CT. this within the secondary of the CT
is reborn to voltage employing a current-to-voltage convertor. This signal
is fed to analogue to digital convertor. A small controller is typically used
and it'll drive the show circuit for this reading.

Types of Measurements Clamp Meter Can Take?
This measurements area unit correct solely to the resolution of the instrument.
AC Current, AC and DC voltage, and resistance area unit measured by clamp
meters and area unit typically well understood. Clamp meters conjointly live
continuity that may be a fast check to see whether or not a circuit is open or
closed. Several clamp meters will browse the frequency of associate degree
AC current undulation, permitting the operator to trace down harmonic problems
in associate degree electrical distribution system. MIN easy lay storage may be
a feature some clamp meters offer that compares every reading against all
antecedently holds on readings. If a reading is lower or more than a hold on
reading, it replaces that reading. All-time low and highest readings over an
amount of your time will so be compiled. “In-rush” current, or the number
of current drawn by a motor throughout startup, is another feature incorporated
in some clamp meters. This knowledge may be understood to see the condition
and loading of a personal motor.
