    Troubleshooting - Frequently Answered Questions MALÅ Easy Locator Pro HDR has been design to be robust and reliable under adverse conditions. If you encounter a mechanical failure that cannot be fixed on site, please contract MALÅ Geoscience or your MALÅ Geoscience representative for advice. System Malfunctions Most malfunctions are power/data communications or user settings related.

  • Page 49: Glossary

    Glossary Auto-Gain Similar to Time-Gain except the software decides the coefficients to be applied to give a response across the depth range without over amplifying the trace. Background removal Background removal is used to remove horizontal and nearly horizontal features in the radargram by subtracting a calculated mean trace from all traces, sample by sample.
  • Page 50 Navigator The push-turn knob fitted to the MALÅ Monitors & Easy locator Controller that acts in a similar way to a computer mouse allowing the user to navigate menus and update data. Rotating the knob either allows sequential scrolling through menu options to make a menu selection or changes selected parameter values.
  • Page 51 Time-Gain Time-Gain applies a time-varying gain to compensate for amplitude loss due to spreading and attenuation. The trace is multiplied by a gain function combining linear and an exponential gain, with coefficients set by the user. Trace A "trace" is a single, vertical column of GPR data, representing the signal "traced" by a radar pulse as it travels from the instrument into the subsurface.
