HGS911HD Balancer / Vibration Spectrum Analyzer / Data Collector
HGS911HD is an easy operate and small sized economical vibration Spectrum analyzer & data collector. It can be used for overall vibration measurement, spectrum analysis and measurement of high frequency acceleration envelope design makes it very effective for bearing fault detection. HGS911HD testing data can be outputed to computer for database and trending analysis.
It is also a low-cost, easy-to-use balancing meter with the measurement of Amplitude,Rotation speed RPM, & Phase measurement.
Features:
Easy to use FFT spectrum analyzer, 400 lines
Measurement of high frequency acceleration envelope makes it a very effective bearing fault detector
Download from computer database point / location ID & upload overall value to database for trending
Powerful standard condition monitoring software
Parameter selection of Acceleration, velocity, displacement and acceleration envelope for FFT.
USB 2.0 interfaces to computer

Trouble-Shooting
| Symptom |
Trouble-shooting |
| The magnetic mount has no attraction force |
Take off the protective iron cover on the bottom of the magnetic mount. |
| Cannot power on. |
1. Press and hold the On button for around 5 seconds then release;
2. The voltage of the battery may be low. Recharge the battery.
|
| Spurious point name appears |
1. Format the memory
2. The battery voltage may be low. Recharge battery and power on again.
|
| Measurements not stable |
- The accelerometer cable does not connect well, firm it at both ends;
- There exists short circuit or break in the accelerometer cable.
|
| Communication fault |
- The communication cable does not connect well, firm it at both ends;
- Wrong model type selected in HUATEC Wave software, re-select the model HGS911HD
- Computer software faults. Re-install HUATEC Wave or scan for virus.
|
If other faults are found, make detailed records and contact HUATEC Group Corporation, www.huatecgroup.com.
Maintenance
Battery Charging
Rechargeable battery is used in HUAEC Group HGS911HDD data collector. It will take several hours to fully charge the battery and then it will be ready for >20 hours of continuous operation.
Calibration
HUAEC Group HGS911HD and accelerometer should be calibrated periodically. The cycle of calibration is normally one year.
