Data Collector Maintenance
WHY?
- Unwanted shutdown of your collector while taking a measurement.
- Collecting data all day only to realize that the data could not be used.
- Having a problem with your data collector and not having the availability of a spare part.
VISUAL INSPECTION:
- Accelerometer or any transducer are in good condition and clean.
- Magnet is well fixed to your sensor.
- Connectors of the cable slack are protected and not damaged or have any visual sign of corrosion.
- Cable or the armature are not cut or burnt.
- No foreign matter in the connectors that could give you false readings or damaged your equipment.
- Straps of the collector are in good condition and well fixed.
ERROR SYMPTOMS:
- Analog input saturation
- Overall levels abnormally high
- Non-repeatability of your readings
- Intermittent operation
- Abnormal time waveform and/or spectrum signal
Should you have a doubt with the data collected, do a counter verification with a different transducer or cable, if possible. Some data collector allow you to perform a ‘’Bias voltage’’ readings of your accelerometer. The ‘’Bias voltage’’ could differ from the manufacturer, generally between 7 Vdc to 14 Vdc.
| Bias Output Voltage 10-14 VDC |

Yearly, verify the certificate of calibration of your instruments and your transducers is recommended by the manufacturer. Dropped sensors should be verified.
STORAGE:
- Sheltered from humidity.
- No heat sources.
- Dust free environment.
- Cables should be safe of cut, burnt, twisted or crushed.
