  • 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 *** It is recommended to put the Archer field computer on charge when not in use to avoid discharge of the battery. *** 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.

  • 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: Equipment List

    3. Equipment List When receiving a GDD MPP probe, model MPP-EM2S+, ensure that its contains the following elements: 1. One (1) MPP-EM2S+ wireless probe 2. Four (4) rechargeable AA batteries with charger 3. One (1) MPP wall power supply with international plug kit (universal voltage) 4.

  • Page 22: Display

    9. Display The main screen displays three sections: The menu bar (1), the displayed measurements (2) and the memory space (3). Several times per second, the probe measures and displays three physical properties which are: HF RESPONSE: Conductor response measured in Hertz (Hz). It measures high frequency variations. Its value increases with the quantity of conductive material in the sample.

  • Page 23: Setting Parameters

    10. Setting parameters To set the parameters of the reading modes, click on the CFG menu of the main screen. In this menu, it is possible to set Reading, Sound, Reinit, Memory and Diameter parameters. 10.1 Reading Keyboard 1: Identification This field allows you to identify your reading series.
  • Page 24 2: Spacing This parameter sets the distance between two readings. If the readings are taken with regular spacing, only one entry is needed. You can enter up to three distances, one for each of the three boxes. If the spacing is different at each reading, it is also possible to set the distance manually (see Section 11 –...
  • Page 25 10.3 REINIT page The initialization is the operation that restores the readings to zero. 1: Initialization time Remember: it takes at least 40 minutes for the probe to warm-up. Before that time is reached, you need to initialize the probe every minute or before each reading. After the probe is ready, it is possible to set the time between two initializations.
  • Page 26 10.4 Memory To be able to download the recorded readings in your personal computer, a file must be created with the readings. This step is done with the Memory page. The Memory parameters are set at the end of the process (when the readings are recorded). 1: Identification If you have already entered a name for your readings series in the Reading page, it will appear in this field.
  • Page 27 4: File creation Start the file creation by clicking the File Creation button. Make sure that you correctly set the Identification and Memory range parameters before starting the file creation. If the file is created after many hours of operation (with a lot of recorded readings), it is possible that the file will take up to twenty minutes to be created.

  • Page 29: Reading Modes

    11. Reading modes In this section, the settings mentioned are those in Section 10 – Setting parameters. It is possible to take readings by using four different methods with the MPP-EM2S+. These methods are manual, continuous, graphic and single reading modes. 11.1 Manual mode Needed settings (Reading page in the configuration-CFG menu): Spacing, Depth, Unit.
  • Page 30 1: Spacing button This button indicates the activated spacing. If more than one spacing has been configured in the three boxes of the parameter (Section 10.1), it is possible to switch between the spacings by clicking on this button. 2: Depth field This field shows the depth where the next reading must be taken.
  • Page 31 6: PLEASE INIT message By default, this message appears every minute. When it appears, a probe initialization is required. If the probe is not initialized after 30 seconds, the GDD logo with the message PLEASE INITIALIZE will appear and the readings will stop. The readings will resume when the probe will be initialized (you just need to press the readings space).
  • Page 32 11.2 Continuous mode In this mode, the readings are recorded automatically according to the recording frequency you need (every second, every five seconds, etc.). Marking different positions along the core sample will help you to have a more accurate graphic. Needed settings (Reading page in the configuration-CFG menu): Space, Depth, Unit, Recording frequency.
  • Page 33 3: Memory space The readings are recorded automatically according to the recording frequency (Reading page in the configuration-CFG menu) you need (every second, every five seconds, etc.). To start the recording, click on this space or push the MEM button of the probe. Use the same way to stop the recording.
  • Page 34 7: PLEASE INIT message By default, this message appears every minute. When it appears, a probe initialization is required. If the probe is not initialized after 30 seconds, the GDD logo with the message PLEASE INITIALIZE will appear and the readings will stop. The readings will resume when the probe will be initialized (you just need to press the readings space).
  • Page 35 11.3 Graph mode The graph mode allows you to visualize the readings graphically in real time. The curves of HF Response, magnetic susceptibility and conductivity are shown simultaneously. In this mode you cannot record data. 1: Vertical axis This axis has a logarithmic scale (from 0 to 100 000). The axis units are Hertz and MHOS/M. The magnetic susceptibility has no unit but the values shown are 10 times higher than the real values.
  • Page 36 4: CONFIG button This button allows you to set the parameters of the graphic mode. These parameters are the sampling frequency, the horizontal axis scale and the width of the lines draft on the graph. The sampling frequency can be selected from 0.1 to 5 seconds. For example, the reading will appear on the graph each 0.1 second if you have selected 0.1s.
  • Page 37 11.4 Single Reading mode The single reading mode initializes the probe and allows 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 38 3. Readings space (Initialization) Pressing the GDD Logo or the readings space will initialize the probe and start the 05 seconds timer. Touching the readings space again will reinitialize the probe and reset the 05 seconds timer. 4. Memory button Pressing the Memory space on the Archer field computer or push the MEM button on the probe for the first time will initialize the probe.
  • Page 39 3. When “-----“appears, position the probe on the sample and press the MEM button to take a reading. 4. Repeat steps 2 and 3 to take several readings. 5. When done, select Single Reading from the CFG menu to deactivate this mode. Instrumentation GDD Inc.
