Page 6: Introduction
VibChecker is designed as a maintenance aid. In accordance with the international standards, it measures vibration severity over the frequency range 10 to 1000 Hz. It allows a practical classification of machine condition in relative terms: good, acceptable, just tolerable, or bad. -
Page 7: Instrument Overview
The instrument has a built-in probe sensor (A). The external sensors with magnets TRM100, TRM120, and all types of SPM vibration sensor series SLD for permanent installation can also be used, connected to the sensor input (G). It is push-key controlled and basic measurement setup information is entered manually. -

Page 19: Using External Sensors
Using external sensors VibChecker can be used with all accelerometers of type IEPE (ICP ) with voltage output. ® To configure VibChecker for measurement with an external vibration sensor: 1. Connect the sensor to the input connector (mini coax). 2. Go to the Main display (A). -
Page 20: Bias Voltage
Bias voltage When measuring vibration with external sensors, a bias voltage check will automatically be made to check the quality of the signal transmission between sensor and instrument. Part of your signal will be lost in a poor sensor line, so your measuring results will be incorrect. If a measurement is made with a poor sensor line, the instrument will display Bias error. -

(peak) or as the total movement in both directions (peak to peak). Displacement is expressed in micrometers. VibChecker always measures an acceleration signal, which is integrated to obtain the velocity, and double-integrated to derive displacement. Both acceleration and speed are constantly changing. One can measure a peak value of either, but a mean value often gives a better indication of the forces involved in the movement. -
Page 22: Built-In Sensor With Probe
Built-in sensor with probe Measuring points for the built-in probe should be clearly marked. Always measure in the same spot. The probe tip is spring loaded and moves within a sleeve of hard rubber. To maintain a steady pressure on the tip, press the probe tip against the measuring point until the rubber sleeve is in contact with the surface. -
Page 23: Measurement
1. In the Main display (A), select the Measure icon (B) and press ENTER. The Measurement display opens, showing the most recent reading. 2. For a new measurement, point the VibChecker straight at the measuring point and press the probe tip until the rubber sleeve is in contact with the surface (or connect the external sensor). -
Page 24: Recording Readings For Follow-Up

4. To return to the Measurement display, press the BACK key. The stored measurement results (excluding spectrum) can be transferred from VibChecker to a Microsoft Excel file using a downloadable SPM program (http://downloads.spminstru- ment.com). The data in the Excel file can be imported into a CMMS or other software for follow-up. -
Page 26: Spectrum Analysis
Spectrum analysis The purpose of a spectrum is to reveal line patterns associated with machine faults. VibChecker generates an FFT spectrum for pattern recognition. Spectrum display To view a spectrum: 1. In the Measurement display (A), press the RIGHT arrow key. -

RPM. In the spectrum, a red marker will appear at the RPM frequency entered here (C). VibChecker accepts up to 60 000 RPM. 3. Press ENTER to save and return to the Spectrum display where the marker can be seen, or press the BACK arrow key to return to the Spectrum display without saving RPM or setting a marker. -
Page 28: Time Signal Analysis
Time signal analysis In the time signal, the analog electrical output from the sensor is digitized, showing how vibration changes over time. The time domain signal can be a useful complement to spectrum analysis to reveal valuable additional information on machine condition, especially for troubleshooting of gearboxes and low-speed ap- plications (<100 RPM). -
Page 29: Iso 2372
6 are used for heavy reciprocating prime movers and machines which are intended to vibrate, such as vibrating screens. VibChecker is programmed with the ISO limit values and will evaluate the measuring result, provided the ISO machine class number is input in the ISO setup display. On the instrument, a green condition indicator will be shown for good and acceptable ISO values, a yellow indicator for just tolerable, and a red one in cases of unacceptable values. -
Page 30: Definition Of Machine Classes According To Iso 2372
Definition of machine classes according to ISO 2372 The following text is a quotation from ISO 2372 (1974, E, page 6, Annex A). This ISO recommendation has also been published as British Standard (BS 4675, part I). A similar vibration classification of industrial machinery can be found in VDI 2056. -

Page 32: Iso 10816 Part 3
ISO 10816 Part 3 Part 3 treats most of the common industrial machines and is divided into four groups. Further criteria for Part 3 are the rigidity of the foundation and the rotational speed. Concrete foundations are rigid, every thing else falls under flexible. The RPM affects the lower measuring range as well as the limit values.
