Page 9: Product Disposal And Recycling
WaveSurfer oscilloscope is powered by DC Adapter. CLEANING The outside of the WS-DCADAP hardware should be cleaned with a soft cloth dampened with either deionized / distilled water or isopropyl alcohol. Allow the surface to dry completely before returning the instrument to service.
Page 10: Overview
This adapter is used with it mounted on the rear of the WaveSurfer oscilloscope as shown in Fig. 1. Connect the adapter to a battery using the special input cable (WS-DCADAP cable). The input voltage supplied from a battery is converted to 24 Vdc and output to the DC IN connector at the rear of the oscilloscope.
