When using a dial indicator for alignment, what is a key factor to check?

When using a dial indicator for alignment, it's crucial to ensure that all of the mentioned factors are in check to achieve accurate and reliable results during the setup process.

First, the dial making contact through 360 degrees ensures that the measurement is consistent and valid from all angles. This is essential for capturing any deviations in alignment accurately and enables the millwright to make the necessary adjustments based on those readings.

Second, the dial plunger not sticking is vital because a sticking plunger can lead to false readings. If the plunger does not return smoothly to its original position after being pushed, it can cause misleading measurements that might result in improper alignment.

Additionally, ensuring that the dial indicator moves positively when pushed in confirms that the device is functioning as intended. This positive movement reflects that the indicator is responsive and accurately tracking the movement of the equipment being measured.

Collectively, these factors contribute to the precision and effectiveness of the alignment process, thus making it important to consider all aspects when using a dial indicator. Ensuring that each of these components operates correctly enhances the overall reliability of the alignment measurements taken.
