Brief Introduction
Vibration test is a crucial method of monitoring device condition and diagnosing malfunction. The utilization of handheld vibration meter improves the production safety, product quality and production efficiency. The application gets piezoelectric accelerated sensor which turns vibration signal into electrical signal, the device works by processing and analysing the input signal, and shows vibration acceleration, velocity, displacement value on screen. It is used widely in machine manufacturing, electric power, metallurgy and vehicle manufacturing fields.

Specifications

Attentions

• Do not use it in high temperature and humidity environment.
• Do not use it nearing corrosive materials.
• Do not use it if it could be splashed.
• Do not use it in chemical gas condition.

Preparation

Battery Installation
Open the cover, put 2*1.5V AAA batteries in according to right polarity.

Probe Installation
There are different probes for different purposes
(tips: different probe corresponds with different purposes for different meets)

1. Short probe is utilized in common for regular testing, and the result is reliable.
2. Long probe is for some places where short probe can not reach , which is good for regular testing. (However, it is not suggested to use this longer probe for testing in high frequency acceleration testing, because of the quick decreasing of high frequency.)
3.  No probes, it’s crucial that the head is contacted well with the measuring point for the best frequency response result which is in range of 10Hz~10KHz.

General Regulation
In frequency range of 10Hz~1KHz, short and long probes are reliable for displacement, velocity and acceleration, but it is suggested to use short probe for high frequency acceleration testing. The bearing stress on sensor should be even, and do not impact the sensor to avoid split of transistor.

Operating Instructions

Power on/off
Short press to turn it on, long press to shut it down.

Measure and Data-locking
Press firmly to test, loose it, the reading remains same.
Attention:

1. The stress acted on the tested object is 0.5~1.0kg
2. The probe should be vertical with the surface of tested object for accurate result.

For Example:

Acceleration Measurement in Low Frequency
The applicable frequency range is 10Hz~1KHz. Operations as follows:

1. Short press SET
2. Choose Acceleration/Low Frequency by UP/DOWN
3. Short press SET to enter this testing mode or press BACK to return

Others

General Problems

1. Cannot be power on: Out of battery.
2.  No result for acceleration testing: switch different frequency testing mode, for instance, switch low frequency acceleration into high frequency.
3. The acceleration reading is unstable: check if the sensor and probe are loose. Tighten it, then test again if it is.

Maintenance

1. Working environment: the vibration meter is a precise device, so keep it strictly from crash, impact, humid, strong current, magnetic field, greasy and dust environments.
2. Changing batteries and maintenance
   • Please change batteries when on LCD screen shows low-power icon .
   • Please take batteries out if no operations for a long while, in case the leakage of batteries which can severely damage the device.
3. Do not disassemble or reform inner construction of this device.
4. Surface cleaning: Ethyl alcohol、diluent have corrosive effect on the body surface of the device, especially the LCD window, so please just scrub it gently with a bit of pure water.

Appendix

• **Machine vibration grading form(ISO2372)

Attention:

**

1. Ⅰtype is small-sized motor that its power is below 15kw;Ⅱtype is medium-sized that its power is from 15kw to 75kw;Ⅲ type is large-scale original motor(based on hardness connection); Ⅳ type is based on resilient connection.
2. Vibration grades:A,B,C,D grade. A for good, B for satisfaction,  

C for unsatisfaction, D for unallowed. Measure velocity RMS value should be in three orthogonal directions of the bearing cap.
