Page 3: Safety Precautions
Do not vary the input power source voltage level (IE...Connected to a variable AC power source). The TR-MARK III auto-senses the input power from the mains plus from 100 to 240 vac 50/60Hz. Varying the input voltage will cause the test voltage to vary and result in a higher or lower test voltage than indicated. - Page 4 Because of the danger of introducing additional hazards, do not install substitute parts or perform any unauthorized modification to the instrument. Return the instrument to a Raytech service department for service to ensure proper operation and that safety features are maintained.
