What are some of the advantages of the digital Fowler QuadraTest Electronic Test Indicator over older dial style indicators? The main advantages of the Fowler QuadraTest Electronic Test Indicator over older dial style indicators relate to the way in which the measurement data is recorded, stored, and transmitted. From the initial step of taking the measurement, the electronic indicator will give a precise measurement without risk of a human misreading the dial. That data point can then be transmitted electronically, further removing any possible error made by a person reading the number and transcribing it incorrectly. All of the data points measured by the electronic indicator are easily sent and stored on a computer, formatted for any analysis that will occur. All of this results in much faster measurements, guaranteed to be more exact. Finally, the Fowler QuadraTest Electronic Test Indicator has the capability to switch back and forth between metric and inch units. This prevents error and enormously speeds of the process of changing or updating the data. Overall, the digital test indicators exhibit an increased amount of control over the measurement process.
