  • Page 3: Warnings: Measure Stability And Battery Discharge

    WARNINGS: Measure Stability and Battery Discharge Measure Stability (Drift) The MPP-EM2S+ is a useful geophysical instrument that will help you to get the information that you need to design an appropriate geophysical survey. In order to obtain stable values (which should be around 0) and avoid signal drift, it is highly recommended to leave the probe ON during one hour before taking the first measurement.
  • Page 4 Battery Discharge *** For the probe, when the level of the AA batteries charge is low, the value of the readings could be inaccurate and you could not be able to initialize the probe. The specifications described in this Instructions Manual is valid at temperatures between 0°C and 70°C.

  • Page 5: Introduction

    1. Introduction Thank you for choosing the MPP-EM2S+ Multi Parameter Probe developed by Instrumentation GDD inc. to help you optimize your prospecting efforts. This probe will help you to better determine the nature, the exact position as well as the intensity of magnetic/conductive horizons along your cores and samples.

  • Page 6: Mineral Conductivity - General Rules

    2. Mineral Conductivity – General Rules Pyrrhotite often occurs in thin but continuous veins. It causes multiple and very high EM anomalies. Chalcopyrite is hardly detectable for two reasons. 1- It is 20 times less conductive than pyrrhotite. 2- It occurs, more often, in disseminated grains or clusters rather than in continuous beds, as the pyrrhotite or graphite that extend in horizons of hundreds of meters.

  • Page 7: Android Software

    3. Android software The MPP Probe model MPP-EM2S+ can be used with any Android devices supporting Bluetooth or Serial (RS-232) communication. The GDD MPP Android software is available on Google Play (https://play.google.com/store/apps/details?id=com.gddinstrumentation.gddmpp). Generally, Android devices don’t have any RS-232 port. To use the probe with the serial communication cable, you would need an USB/RS-232 adapter like the one shown below.

  • Page 12 6.3 STAMP and MEM buttons There are two buttons on the handle of the MPP–EMS2+ probe. These buttons have the same utility as the Stamp and Mem buttons in the GDD MPP Android software and were designed to facilitate handling. Pressing the both buttons together initializes the probe, so it makes the same action as Initialize button in the GDD MPP Android software (for the firmware versions starting from MPPi5_6).

  • Page 32: Reading Modes

    9. Reading Modes It is possible to take readings by using three different methods with the MPP-EM2S+. These methods are Punctual, Continuous and Single Reading modes. Punctual mode In this mode, each time you click MEM button in the GDD MPP software or you press MEM button on the probe, one reading is stored in the current project.
  • Page 33 Single Reading mode In this mode, you have to initialize the probe before taking a single reading. After the probe is initialized, you have 15 seconds to take a reading before you have to reinitialize the probe. The reading values will be displayed on the screen with a resolution of 10 SI for readings lower than 10 x 10 SI.
  • Page 34 This reading is associated to the selected Core and taken at the current Depth position. If the current Spacing is not 0, the current Depth is incremented by the value of Spacing and the next reading will be stored at this Depth position. Instrumentation GDD Inc.

    12. Readings interpretation 12.1 HF/Cond Distinction In the case of conductive sulphides: The HF response provides an indication of sulphides quantity. The Conductivity (Mhos/m) provides an indication of sulphides quality. The conductivity of a small and a large aluminium foil will be similar but the HF response will increase with the size of the aluminium surface.
