Get Application For Approval As A Workshop For Recording Equipment (Approved Tachograph Centre) GV207

The sticker is usually put on the B pillar of the drivers door or sometimes on the drivers seat base. Just make sure that the day you are driving the vehicle is within 2 years of the date shown on the sticker. Both the driver and employer commit an offence if a vehicle is used outside the calibration period.

Digital tachographs must be calibrated every two years. If they have had any repair, if the vehicle registration changes, and/or if an alteration to the circumference of the tyres changes, they must be re-calibrated straight away. If any equipment breaks or becomes faulty, it must be repaired as soon as possible.

In the case of the tachograph, the parameter responsible for the calibration is called the K factor which represents the number of pulses that should be received by the tachograph when the vehicle drives a one kilometer distance.

Who can fit, seal and Calibrate Tachographs? All tachographs used for recording driver's hours, whether analogue or digital, must be properly installed, calibrated and sealed. This task must be performed by either a vehicle manufacturer or an Approved Tachograph Centre.

Explanation: An analogue tachograph must be checked every two years and recalibrated every six years. A plaque on or near the tachograph will show when it was last checked.

Digital tachographs: Must be calibrated every two years. Must be calibrated after any repair. Must be calibrated if the vehicle registration number changes. Must be calibrated if UTC is out by more than 20 minutes.
