2. How to use
Hold the sensor against the measured part and try to keep the vibrating pen perpendicular to the measured surface. Press a button to start measuring.
Hold the sensor against the measured part and try to keep the vibrating pen perpendicular to the measured surface. Press a button to start measuring.
The measuring range of this machine is 0.1～199.9mm/s(rms). When the upper limit of the measurement is exceeded , it will be displayed 
. If the button is released, the LCD will display "HOLD", and the measured value at the moment before the button is released will be held. About 40 seconds, and automatically shut down.
When the LCD displays "BATT", it means that the battery should be replaced, otherwise the accuracy of the measured value cannot be guaranteed. When changing batteries, please replace both batteries at the same time. ", it means that the battery should be replaced, otherwise the accuracy of the measured value cannot be guaranteed. When changing the battery, please replace the two batteries at the same time.

4. Matters needing attention
Note 1: When replacing the battery, pay attention to the positive pole of the battery facing " 
".
Note 2: This machine has no data memory function, if you need to keep the test data, you need to make a written record.

Note 3: The measurement point should be selected on the bearing, bearing support or other structural components that have a significant response to the dynamics and can represent the overall vibration characteristics of the machine; in order to determine the vibration characteristics of each measurement position: the measurement point should be selected on the bearing , bearing supports or other structural components that have a significant response to dynamics and can represent the overall vibration characteristics of the machine; in order to determine the vibration characteristics of each measurement position, it is necessary to measure in three mutually perpendicular directions. It is necessary to measure in three mutually perpendicular directions .
Keep the pen vibrometer perpendicular to the surface of the measured object during measurement. The sensor head of the pen-type vibrometer should be in close contact with the surface of the object to be measured, and the pressure should be about 1. Keep the pen-type vibrometer perpendicular to the surface of the measured object during measurement. The sensor head of the pen-type vibrometer should be in close contact with the surface of the measured object, and the pressure is about 5-20N, so that the vibration of the measured object can be accurately transmitted to the sensor.
