Electronic Digital Calipers

Electronic Digital CaliperElectronic Digital Calipers have been used by engineers for many years.

For those who are contemplating purchasing one for the first time or are having problems using them this is a short guide to explain the usage of it.

 

 

The image above has the main operating components labeled and they are the following:

  • Internal measuring jaws.
  • Measurement display.
  • Depth probe.
  • Thumb screw.
  • Thumb locking screw.
  • External measuring jaws

 

First ensure the external jaws are clean and are completely free of dust or any other foreign body..
Then close the jaws and switch the caliper off and on and the measurement readout should be zero.

To take an external measurement, open the caliper and then close the caliper on the object being measured.

.The caliper jaws should be at right angles to the object.

.
To make inside measurement close the jaws and insert them into the object and open them keeping the jaws at right angles to the surfaces being measured..
To take a depth measurement close the jaws and set the non moving end of the caliper on the top of the object..

Then move the movable part so that the depth probe extends out to the depth of the object.

.
Ensuring in all cases that the caliper is at right angles to the measured object..
There is a thumb screw on top of the caliper above the measurement readout display.

This when tightened locks the sliding part of the caliper which allows a measurement to be taken and held.

This permits a measurement to be take and locked if it is in a position that the readout cannot be seen until the caliper is moved.

.
Under the readout there is a switch the can change the readout from inches to decimal..

This is a correct transformation from one measurement to another.

.

There are several videos on You Tube showing these operations.

Please note:
If viewing from Canada, France or United Kingdom articles selected to view may be substituted for an equivalent model if the selected model is not available in your country.

However reading some of the reviews there seems to be a relaxation on quality control.

Recommendation of Electronic Digital Calipers

Of the 5 Electronic Digital Calipers reviewed there are 2 that are on level terms for performance and accuracy.

They are the following:

Digital Caliper – Stainless Steel – Large LCD Screen – FREE Feeler Gauge Included – & Extreme Accuracy – Inch/Metric Conversion

and

Dr.Meter 6″ Digital Caliper Stainless Steel Venire Caliper Gauge Micrometer with Electronic Large LCD Display Inch Decimal Millimeter Auto off Measuring tool,Black

The price difference was not the deciding factor as they were in the mid range the cheapest was reflected in its poor review results, this does show that it is necessary to pay that little extra for quality.
