Warranty Information
No specific warranty period is mentioned in the document.
The 4234 600 and 4234 601 are Katharometer power supply units (PSUs). They provide a stabilized DC supply for operating a katharometer and an auxiliary 10 V DC supply for temperature control. Installation involves mounting the unit, connecting the AC mains input, and connecting the DC output and 10V cables to the katharometer. Fuse replacement is the only user-serviceable task. Ensure the correct unit version is used for the available supply voltage.
