    C.Scope Signal Generator (pre 2003) MUST be carried out on every unit. It is important to note that the Function Checker does not recalibrate, service, repair or alter in any way, the operation of any C.Scope product.

  • Page 5: Using This Manual

    Using this Manual The Function Checker allows Performance Checks to be carried out on a wide range of C.Scope Cable Avoidance Tools, Locators, Signal Generators and Transmitters with each model covered in a specific section of this manual. It is essential to identify exactly which C.Scope product you wish to test before attempting any of the Checks.

  • Page 6: Features

    Features Terminals. The Function Checker LCD indicates: Control buttons. Liquid Crystal Display (LCD) Operating frequency (where appropriate). Power mode. Radio mode. Method of Testing. Battery condition. Signal levels received when testing Signal Generators or Transmitters.
  • Page 7 Features ON/OFF The Function Checker will automatically turn off five minutes after the last button press. MODE Selects and cycles through the four modes of operation: for testing the induced output signal of C.Scope Signal Generators and Transmitters. for testing connected output signal of C.Scope Signal Generators and Transmitters.

  • Page 8: Selecting A Suitable Location

    Selecting a suitable location In order for the Function Checker to correctly Performance Check a C.Scope product it is important that there are no strong background electromagnetic signals present that may cause interference. Therefore, the intended location for using the Function Checker should be checked for background electromagnetic signals before use.
