Page 5: Introduction
Introduction Thank you for purchasing your product from Castle Group Ltd. The Castle Pocket Vibration Meter range has been designed to deliver cost effective vibration measurement solutions. Your instrument can cater for various degrees of experience with it being simple to to operate and interprate the measurement results. -
Page 6: Measuring Vibration
Measuring Vibration It is advisable to validate your instrument prior to, and after taking measurements using a known vibration source such as the Castle GA606 Vibration Calibrator. To ensure measurements are as accurate and as repeatable as possible always ensure that your cable is tightened securely to your accelerometer and that the accelerometer is mounted as securely and as flush as possible to the vibration source. - Page 7 The result of this equation is the contribution to daily exposure and the reason that this is used is to give a measurement to each of a number of processes that may be carried out in one day. To calculate the overall daily exposure from a set of partial exposures, the following equation is used: - ...

Alternatively the stud may be adhered to the device with an adhesive that dries rigid. Castle Group Ltd can supply a glue and stud pack if required, (order code K01215). -
Page 9: Vibration Level
Vibration Level For ease of use and where high levels of vibration may occur, the Pocket Meter Vibration Range has been designed with 2 operating ranges. Before you record measurements take the time to ensure you have selected the optimum range for the process being recorded. Generally 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 10 -1 5.00 -20.00 -25.00 -30.00 -35.00 -40.00 Frequency (Hz) The GA2002 model has a linear frequency weighting filter which does not attenuate any vibration regardless of frequency. The frequency response is shown below: - 1 00 1 000 1 0000 5.00 0.00...
