Acceleration :    0.01 g to 20 g.

LCD display of current levels updated every 10 second, maximum level during last hour and maximum level during current measurement period.

Up to 300 events or several weeks continuous recording may be stored in the non volatile memory and quickly downloaded to a PC.

Uses 2 ordinary alkaline D cells which will power the system for up 20 days.

Manufacturer's Specifications

Robust, weatherproof and lightweight - kit includes PC download software with a cable.

VDV - Vibration Dose Value
When using the VDV transducer to measure vibration dose, the instrument complies with BS 6472 and BS 7482 part 3 with automatic day/night change over. Both 30 second and 1 hour dose levels are recorded and the resultant 16 or 8 hour values calculated in the range 0.025 to 10 m/s^{- 1.75}. You can still record the PPV levels etc., on the other channel.

Manufacturer's Specifications

Robust, weatherproof and lightweight - kit also includes PC download software with a cable.
