Important information
ISO
ISO standards
VibChecker is a handheld instrument for fast and easy measurement
of machine condition in preventive maintenance. It is based on the
recommendations of ISO2372 and ISO10816 standards for broad
band measurements of vibration. These standards make the assumption that limited information, obtained easily and at a low cost, is
often as useful as a detailed analysis using expensive equipment and
elaborate techniques.
- The instrument is intended for professional, industrial process, and
educational use only while taking into consideration the technical
specifications.
- Charge the battery within the charging temperature range (0° to +45
°C) in a dry office environment, otherwise it can become damaged.

Class V Drive systems on stiff foundations with unbalanceable inertia effects
Class VI Drive systems on soft foundations with unbalanceable inertia effects
- Charge the battery before storing the VibChecker for a longer
period of time (>6 months). The reason for this is that the cells can
not withstand being fully discharged.
- The instrument must be sent to a certified SPM Instrument service
and calibration partner for replacement of a discharged battery.
- When measuring, ensure that no cables etc. can be caught in rotating parts which can cause injury.
- Service and repairs of the instrument may only be performed by
SPM Instrument authorized service technicians.
- Never use alcohol or ammonia-based cleaning fluid to clean the
instrument screen.

Part 2
Large land-based steam turbine generator set in excess of 50
MW. Machine speed either 1500/1800 RPM or 3000/3600 RPM.
Part 3
This part treats most of the common industrial machines and is
divided into four groups:
Group 1 Large machines with rated power above 300 kW and not more
than 50 MW; electrical machines with shaft height above 315 mm.
Group 2 Medium machines with rated power above 15 kW up to and
including 300 kW; electrical machines with shaft height from
160 mm to 315 mm.
Group 3 Pumps with multivane impeller with separate driver (centrifugal,
mixed flow or axial flow) with rated power above 15 kW.
Group 4 Pumps with multivane impeller with integrated driver (centrifugal,
mixed flow or axial flow) with rated power above 15 kW.
Part 4
Gas turbine driven sets excluding aircraft derivates with power output
of at least 3 MW. Limit value table depends on RPM of the turbine.
QuickStart
- For safety reasons, the instrument must only be operated and
maintained by properly trained personnel.

Measuring:
1. Hold the BACK key to switch on the instrument.
2. Select acceleration, velocity or displacement, and what results to
show, in the AVD menu under General settings.
3. Select ISO standard (off, ISO2372 or ISO10816) for evaluation of
­machine condition in the ISO menu.
4. When measuring with built-in probe:
Point the VibChecker straight at the measuring point and hold it
steady during measurement. Press the probe tip until the rubber
sleeve is in contact with the surface, and then press the MEASURE key
from the measurement window.
When measuring with external sensor:
Connect the external sensor to the input at the top of the
VibChecker. Place the external sensor in accordance with the user
guide and then press the MEASURE key from the measurement
window.
The green, yellow or red symbol indicates the machine condition. For
