HOW TO MEASURE CURRENT FLOWING IN A CIRCUIT USING CLAMP METER?
Clamp Meter
A clamp meter is a device that is used to measure current conveniently and safely. It is very efficient in measuring current without using test leads. To measure current, all you have to do is place a wire in the clamp meter's claws. When current flows through a conductor, a magnetic field is generated. This device helps to detect the magnetic field so that the corresponding current reading can be provided. Dedicated clamp meters do just one thing – measure current, but most technicians carry combination clamp meters that also function as their multimeter (like with the popular Fieldpiece meters).


How does clamp meter measures a flowing current?
    A clamp meter works on the magnetic induction principle to measure AC without contact. Like every conductor, the current flowing through a wire produces a magnetic field. The Hall Effect sensor detects the magnetic field created by current flow to create less voltage across the sensor. We can say that this sensor mainly detects magnetic fields that are caused by low current flow.

Additionally, in the following guide, the steps are only for measuring DC amps or AC amps. For all other quantities, the process is similar but you will have to select the respective function in the dial.

   Steps to Follow While Using a Clamp Meter to Measure Current

Step 1
Switch ON the meter and remove the probes (if attached)

Step 2
Select the AC current or DC current function using the dial.

The display should show a jaw sign, which will confirm that the measurement is being detected through the clamp (Read the user manual to see how your meter indicates this)

Step 3
Open the jaw-like structure using the side lever and insert the conductor through which the current is to be measured

Technicians can do this with their secondary hand so that measurements can be noted down using the primary one

Step 4
Then close the jaw-like structure and level the conductor between the alignment marks inscribed on the jaws.

If these marks are not shown in your model, try to adjust the conductor in the center of the clamp

Step 5
The display will show the appropriate reading. Users can change the resolution as per requirements, but most meter models do this automatically.

It is recommended that all measurements should be taken for conductors that are insulated properly. DO NOT measure around live wires.

HYDROMETER How to Measure the condition of a lead-acid typed battery using Hydrometer?  Hydrometer A hydrometer is an instrument used to determine specific gravity. It operates based on the Archimedes principle that a solid body displaces its own weight within a liquid in which it floats. Hydrometers can be divided into two general classes: liquids heavier than water and liquids lighter than water. In the standard hydrometer scale, known as the specific gravity scale, distilled water equals 1.000, the initial point of measurement. Liquids lighter than water are scaled below 1.000 specific gravity, and liquids heavier than water are scaled above 1.000 specific gravity. Function and Use A hydrometer is made up of a thin glass or plastic tube sealed at both ends with a graduated or printed scale calibrated to a specific gravity. One end of the tube is bulb shaped and weighted with a ballast of either fine lead shot or steel shot. The ballast causes the instrument to float ...
