How to ensure an accurate measurement using IRD301 Vibration Meter?
IRD301 is a Digital Vibration Meter that measures Overall Vibration Amplitude in Velocity mm/sec RMS. To ensure an accurate measurement using IRD301 - please refer these steps as guide:
- Ensure that both your Vibration Meter IRD301 as well as Vibration Sensor IRD521 carry a valid Calibration status. We paste a tamper evident calibration sticker on both prior to dispatch. It mentions the last calibrated date and the next calibration due date. A Calibration Meter and Sensor will ensure an accuracy of +/- 10% of expected reading.
- Ensure that you are using a healthy 9V battery. A battery with potential 8.3V or less will lead to Low Battery Indication and inaccuracy in measurement
- Ensure you are using the correct cable having connectors for IRD301 and IRD521 and you are not forcing non-standard connectors onto IRD301 or IRD521 or using non-shielded wires.
- Ensure that IRD521 is hand mounted, stud mounted, stinger mounted or magnet mounted properly onto target surface. If taking vertical vibration - ensure that sensor is kept straight vertically and the angle to Vertical is below +/- 10 Degrees
- Pro Tip - ensure there are as less layers as possible between source of vibration and vibration sensor IRD521. For example, avoid motor fan covers that exhibit a vibration totally unrelated to Motor NDE vibration.
- Wait for 2 to 3 seconds after placing the sensor on the target surface. This ensures a settled and stable reading.
Diligently practicing these steps will lead to an accurate measuring using IRD301 Vibration Meter each time and every time.
