Page 23: Cleaning And Maintenance
10 Cleaning and maintenance This multimeter is designed to provide years of dependable service, if the following care instructions are performed: 1. KEEP THE METER DRY. If it gets wet, wipe it off. 2. USE STORE METER NORMAL TEMPERATURES. Temperature extremes can shorten the life of the electronic parts and distort or melt plastic parts. - Page 24 12 Dismantling and utilization Worn-out electric and electronic equipment should be gathered selectively, i.e. it must not be placed with waste of another kind. Worn-out electronic equipment should be sent to a collection point in accordance with the law of worn-out electric and electronic equipment.
