Structure diagram
Usage

Display screen schematic diagram

Push the sensor against the measured area and try to keep the vibration meter perpendicular to the measured surface. Like the versatile vibration measuring pen, use it first“AVD”Use the key to switch measurement parameters, in the order of 'acceleration'（LO）”Acceleration（HI）”Speed, displacement, acceleration（LO）”. Then hold it down“ON/HOLD”Press the key to start the measurement, release it to stop the measurement, and keep the measurement value.

This instrument displays when the measurement limit is exceeded during measurement1 .If the button is released, the LCD display will appear“HOLD”The measured value after releasing the key will remain unchanged20About seconds and automatically shuts down.

When LCD display“BATT”When, it means that the battery should be replaced, otherwise the accuracy of the measurement cannot be guaranteed. When replacing the battery, please replace both batteries at the same time.

precautions

1: Attention should be paid to the positive pole of the battery when replacing it“”Down.

2: This machine does not have data memory function, and written records are required to retain test data.

3: The measurement point should be selected on bearings, bearing supports, or other structural components that have a significant response to power and can represent the overall vibration characteristics of the machine for measurement; To determine the vibration characteristics of each measurement location,It is necessary to measure in three mutually perpendicular directions.

4：Maintain the vibrometer perpendicular to the surface of the object being measured during measurement. The vibration meter sensor should be in close contact with the surface of the object being measured, with a pressure of approximately5～20NIn order to accurately transmit the vibration of the measured object to the sensor.
