Test and Measuring Instruments during Test Drive






Test and Measuring Instruments during Test Drive

If it is necessary to use testing and measuring devices on road tests, observe the following:

CAUTION!
Distraction and improperly secured test equipment can lead to accidents.

There is a risk that the passenger airbag could deploy in a collision.

Operating testing and measuring equipment while driving creates a distraction.

There is an increased risk of injury due to unsecured testing and measuring equipment.

Always secure testers on the rear seat with a strap and have a second person on the rear seat operate them.
