How to Use a Digital Dial Indicator?

Digital dial indicators are relatively common in daily life. It is a length-measuring instrument that converts general linear displacement into rotational movement of a pointer through gears or levers and then reads on the dial. Next, we will introduce you to the steps of using the digital dial indicator and related precautions.

Steps for usage

Start measuring: Before using the digital dial indicator, you need to turn on the power first, usually by pressing the power switch or connecting the power cord. Make sure the digital dial indicator battery is fully charged to ensure accurate measurements.

Choose the appropriate measuring range: Select the appropriate range according to the size and measurement range of the object being measured. If the size of the object being measured is larger, a larger range needs to be selected; if the size of the object being measured is smaller, a smaller range needs to be selected. Make sure that the selected range can meet the measurement needs and will not cause damage to the object being measured.

Adjust the probe: Before using the digital dial indicator, the probe needs to be adjusted. According to the shape and size of the object being measured, adjust the test probe to the appropriate position to ensure measurement accuracy. If the object to be measured is cylindrical or round, the test probe needs to be adjusted to a position perpendicular to the object to be measured; if the object to be measured is flat or square, the test probe needs to be adjusted to be parallel or perpendicular to the object to be measured Location.

Record readings: During the measurement process, you need to always pay attention to the changes in the reading of the digital dial indicator. When the digital dial indicator reading stabilizes, the measurement results can be recorded. If the reading is unstable or abnormal, it is necessary to re-measure and check whether the digital dial indicator is in normal use.

End measurement: After completing the measurement, you need to turn off the power of the digital dial indicator and then return the test probe to its original position. At the same time, the digital dial indicator needs to be placed in a dry and ventilated place to avoid moisture and dust erosion.

Cleaning and maintenance: During use, the surface and internal parts of the digital dial indicator need to be cleaned regularly. Wipe the surface with a dry cloth and use a vacuum cleaner to remove dust from the interior. At the same time, it is necessary to regularly check whether the battery and power cord of the digital dial indicator are normal to ensure the accuracy of the measurement.

Correct placement: When using a digital dial indicator, it needs to be placed on a stable surface to avoid severe vibration and shaking. At the same time, the digital dial indicator needs to be kept parallel or perpendicular to the surface of the object being measured to ensure measurement accuracy.

Regular calibration: To ensure the measurement accuracy of the digital dial indicator, it needs to be calibrated regularly. It is recommended to calibrate according to the calibration method provided by the manufacturer during use to ensure the reliability of the measurement results. At the same time, if the measurement results of the digital dial indicator are found to be abnormal or have a large deviation during use, it also needs to be calibrated or repaired in time.

Things to note when using a digital dial indicator

Measuring range: Before using a digital dial indicator, you must understand its measurement range. Choosing the appropriate measurement range can ensure the accuracy and reliability of the measurement results. If the measurement range is too small, the measurement results may be inaccurate or impossible to measure; if the measurement range is too large, the measurement accuracy may be affected.

Measuring head position: When measuring, you must ensure that the measuring head is in the correct position on the object being measured. If the measuring head position is incorrect, the measurement results may be inaccurate or have a large error. Therefore, before measuring, you should first understand the shape and size of the object to be measured, and choose the appropriate measuring head position.

Calibration and accuracy: Before using a digital dial indicator, it must be calibrated to ensure the accuracy and reliability of the measurement results. During use, calibration should also be performed regularly to ensure the accuracy of the digital dial indicator. If the digital dial indicator is found to have errors or inaccurate accuracy, it should be calibrated or repaired in time.
Installation and fixation: When installing the digital dial indicator, make sure it is firm and stable and will not shake or slip. If the digital dial indicator is not securely installed, the accuracy and reliability of the measurement results may be affected. Therefore, when using a digital dial indicator, you should choose a suitable installation location and ensure that it is firmly fixed.
