Chapter 1 Introduction Thank you for purchasing your VibA(8) vibration meter from Castle Group Ltd. Your new Vibration meter is at the forefront of design and technology and yet has been developed for seamless intuitive operation without the unnecessary complexity of traditional vibration meters. -
Page 7: Chapter 2
Chapter 2 Frequency Weighting Filters The human body’s response to vibration alters depending on the vibration frequency and where the vibration is in contact with the body. Your VibA(8) meter has the following frequency weighting filters which are applied to the measured vibration signal using digital processing for superior accuracy. -

Chapter 3 Accelerometer Details Accelerometers by the very nature of their manufacture are precision components that are easily damaged through incorrect use. Great care must be taken when using the instrument to ensure the longevity of the Accelerometer. Attaching & Removing the Accelerometer Align the orientation keys between the accelerometer cable and instrument socket, which are easily identified with a Red marking and then gently push the accelerometer cable into the instruments socket. -
Page 10: Accelerometer Types
Accelerometer Types The accelerometers for use with the VibA(8) produce a Voltage Output proportional to the signal being measured. The table below shows the output voltage and specifications for the accelerometer where g is the acceleration due to gravity on the Earth’s surface and is defined as 9.80665 ms Acceleration is measured in metres per second per second (m/s/s) which can be written as either of the following: -... -
Page 11: Certifiable Calibration
The calibration process includes the transducer and vibration level meter. Any change in this measurement chain will require a new calibration certificate. Castle Group Ltd offers a complete calibration service offering either a full UKAS calibration or a standard traceable calibration which can be supplied with or without a test report. -
Page 12: Chapter 4
Chapter 4 Measuring Vibration Always calibrate your VibA(8) vibration level meter prior to and after taking measurements using a known vibration source, such as the Castle GA606 Vibration Level Calibrator. Vibration Level – General Advice To ensure measurements are as accurate and as repeatable as possible always... -
Page 13: Hand Arm Vibration Transducer Mounting
Alternatively, the stud may be adhered to the device rather than tapped with an adhesive that dries rigid. Castle Group Ltd can supply a glue and stud pack if required, (order code KD1215). -
Page 14: Vibration Level
Vibration Level In some environments, high levels of vibration may occur. Before you record measurements take the time to ensure you have selected the optimum range for the process being recorded. The optimum range is generally the lowest range that can be selected that does not produce an overload condition for the process being monitored. -
Page 15: Under Range & Overload Conditions
Under Range & Overload Conditions Under Range Condition An under-range condition occurs when the vibration level is equal to, or lower than the bottom of the current range the meter is set to. If this condition occurs then the UR (Under Range) indicator will be displayed on your instrument. -

Page 17: Powering Your Viba(8) Vibration Meter
Powering Your VibA(8) Vibration Meter Your VibA(8) Vibration level meter can be powered from four 1.5V AA size batteries or the micro USB connection via a USB port or similar. The battery compartment is located at the rear of your Vibration meter, remove the battery door and insert the batteries using the correct polarity which is shown where the batteries are fitted and indicated in the image below: - Replace the battery door securely before using the instrument. -
Page 18: Battery Level Indicator
Battery Level Indicator The VibA(8) meter is equipped with an approximate multi-level battery indicator as shown below: - 100% At approximately 5% charge the battery indicator will show flash RED, if the batteries are not replaced the unit will automatically shut down and save the recording if necessary. -

Page 23: Accelerometer Fitting
Accelerometer Fitting Each time a transducer is auto-detected including if powered on with the accelerometer fitted, then a short delay of 60 seconds occurs to allow the hardware time to settle and adjust to the detected accelerometer. Please wait until the countdown completes before measurements are taken. Bypassing the delay by pressing Soft Key 2 labelled O allows access to the menu system, however it is highly recommended to wait 60 seconds before recording data. -
Page 24: Operation
Operation The VibA(8) vibration level meter has three primary operational modes, these are: - • Real Time • Recording • File Review Each mode can be quickly identified by viewing the bottom bar; Real Time has no icon, Record has a standard red record symbol and File Review shows a green directional arrow. -
Page 25: Real Time
Real Time This is the standard mode of operation for your VibA(8) vibration level meter. The menu system can be accessed whilst in real time mode and the instrument settings can be changed if required. Measurement screens are accessible but not all parameters are available whilst real time mode is active. -
