Equipment Repairs & Calibration FAQs

Where and when to have my Stoneridge Workshop Equipment calibrated (conformance tested)

Conformance testing of the following equipment must be carried out every 6, 12 or 24 months (depending on your in Country legal requirements) to check it for accuracy. The check may take place at any time during the month:

• Vehicle Testing Rollers (Rolling Road / RBT Add-On)
• Tachograph Instrument Portable Drive Test Unit (Head tester)
• Clock tester
• Pulse Counter (OPTIMO)
• Adapter for electronic sender units (OPTIMO)

The conformance testing must be carried out by a company independent of the ownership or control of the Approved Tachograph Center.  To ensure compliance of your chosen supplier, please check the level of accreditation required by your national authorities.
