Xtester-S908B Vibration Analyzer Ex Version
overview
1). Check the voltage of the battery:Press M<easure> key, observe the display on the screen. If there is an arrow on the top left corner, you need to replace the battery with a new one. 2). Set-up probe S908B with outside accelerometer has 1 probe and 1 magnetic mount. When changing, take hold of the accelerometer to avoid rotation and damage of the cable. |
Measurement
1). Select the measure parameters:
S908B has 4 vibration parameters. They are:
a) Displacement(unit: mm=1/1000 mm): | Equivalent peak-peak value |
| Velocity (unit: mm/s) : | True RMS Value; |
| Acceleration (unit: m/s2): | Equivalent peak |
| High Frequency Acceleration (unit: m/s2): | Equivalent peak |
Functions of the M<easure> key:
| Key press: Power on and begin measuring; Key release: Hold the last measured value for twenty |
| seconds and then power off automatically. | seconds and then power off automatically. |
| Stick the probe to the measured object | the pressure should be about 0.5-1 kg. |
Notes
Avoid intense impact, high temperature and immersed in water. Keep the sensor plug clean and dry, and use it carefully. Install the battery: 1.Open the small back cover of battery cabinet (2 screws at the end far away from the sensor at backside, see figure); 2. Place a battery (6F22, 9V) correctly according to the polarity; 3. Close the back cover and screw the screws tightly; 4. If it has been put aside long-term, please take out the batteryto avoid the outflow of the battery liquid; 5.If the sensor has been used for over one year, please re-calibrate the sensor and the meter together to ensure the precision |
