  • Page 3: Introduction

    RMO500 should only be operated by trained and authorized personnel. Rules for Use • RMO500 should only be used when in a technically fit condition. Its use should be in accordance with the safety regulations for the actual working site and application.

  • Page 4: Designated Use

    • The serial interface of RMO500 should only have external devices connected that meet the requirements for SELV equipment according to EN 60950 or IEC 60950. • When setting up RMO500, make sure that the air slots of the test set remain unobstructed.

  • Page 5: Functionality

    Functionality 4.1 Single Test The RMO500 generates a filtered (true) DC current and outputs it in an automatically regulated current ramp. The current increases with a constant slope from zero up to a set maximum value. When the current has reached its maximum, RMO500 measures the resistance of the test object.
