  • Page 2 Safety precautions ® The Testboy TB-2200 left our factory in a technically safe and flawless condition. In order to maintain this condition, the user must observe the safety notes con- tained in this manual. Caution! - This operation manual contains information and notes required to operate and use this instrument safely.
  • Page 3 Caution! The instrument must only be used under the conditions and for the purposes for which it was designed and built. Thus, it is imperative to observe the notes on safe- ty, the technical data in conjunction with the ambient conditions and use the in- strument in dry conditions.

  • Page 7: Dc Voltage Measurement

    4. Application description DC VOLTAGE MEASUREMENT Set the selector switch to measurement range V=. Insert the black test lead into the ‘COM’ socket and the red test lead into the right- hand socket. Using the test probes, touch the test points of the test object. The multimeter automatically searches for the most suitable measurement range.
  • Page 8 When carrying out the cable break detection, if the display does not flash and no acoustic signal is emitted, a dangerous high voltage (>33 V AC or 70 V DC) may nevertheless be present. The non-contact sensor can only detect voltage generat- ed by sufficiently strong electric fields from power sources (grids, >100 V AC).

  • Page 9: Dc Current Measurement

    DC CURRENT MEASUREMENT: Set the selector switch to measurement range A. Use the ‘M’ button to set the device to DC. Insert the black test lead into the ‘COM’ socket and the red test lead into the right- hand socket (up to max. 200 mA). You must use the ‘4 A' socket when measuring currents above 200 mA.

  • Page 10: Continuity Test

    CONTINUITY TEST: Set the selector switch to measurement range ‘Ω’. Insert the black test lead into the ‘COM’ socket and the red test lead into the right- hand socket. Using the button ‘M’, set the device to ‘ )) ’. Using the test probes, touch the test points of the test circuit.

Manufacturers of electrical appliances are obliged to take back and recycle all electrical appliances free of charge. Elec- trical devices may then no longer be disposed of through conven- tional waste disposal channels.
