WARNINGS: Measure Stability and Battery Discharge
Measure Stability (Drift)
The MPP3wifi probe 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. After one hour, you must re-initialize the probe and then, you
are ready to take measurements. To minimize the drift once you have started to take measurements,
you should initialize the probe every 1, 5, 10 or 15 minutes. By default, the option 1 minute between
every initialization is activated.
If you prefer to take measurements right after turning on the probe, we suggest that you initialize the
probe every minute or, for best results, before each reading for the first 30 to 60 minutes.
This preventive procedure decreases the risk to take erroneous values that would be caused by
weather variations or by other external causes that lead to a drift of the instrument. It is therefore
very important to often re-initialize in order to maintain the «0» base value used in the calculation of
the displayed values. Please take note that the values are much more stable after 20 minutes and are
completely stable after 50 to 60 minutes.
Battery Discharge
*** When the level of the AA batteries charge is low, readings may become inaccurate and you may
not be able to initialize the probe.
The specifications described in this Instruction Manual are valid at temperatures between 0°C and
70°C. At temperatures lower than 0°C, some specifications, such as the batteries life, may differ.

1. Introduction
Thank you for choosing the MPP3wifi Multi Parameter Probe developed by Instrumentation GDD inc.
to help you optimizing 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. The simplicity of the measurement process and the automatic recording will allow you
to easily obtain conductivity and magnetic susceptibility profiles corresponding to the core.
Here are the key benefits of the MPP3wifi probe:
It provides you the ability to measure at all time the magnetic susceptibility with or without the
presence of a conductor.
Our software allows to measure in continuous mode using a time base with specific lengths of
your choice.
The new MPP web interface allows users to control the MPP probe through a web application
from any device having a web browser (laptop computer, smartphone, tablet, etc.). The data are
stored in the probe itself and the project files can be recalled.
The conductivity values yielded by the MPP probe are generated from our Frequency-Domain EM
inbuilt system. The presence of conductive material in your core or rock sample will induce an EM
response if:
1- It is composed of conductive minerals;
Refer to the literature to learn more about the electrical properties of different minerals, soils,
materials... In general, the EM conductivity of pyrite < magnetite < chalcopyrite < pyrrhotite.
2- Those conductive minerals are interconnected, generating a significant volume;
Note that a small vein of a very conductive mineral may yield a stronger EM conductivity than a large
zone of a moderately conductive massive sulphide. In addition, for an equivalent content of
conductive material, the MPP probe EM response will be proportional to the conductor's surface. You
could try the following experience. Take an aluminium paper foil (a few cm²), put the probe on the
sheet and note the intensity of the anomaly. Roll the sheet in a small ball, put the probe on the ball
and take the reading again. You will see that the intensity of the anomaly is higher for a larger contact
surface even if the substance conductivity and quality are the same.
The MPP probe represents a useful tool when it comes to plan an airborne, ground or borehole EM
survey allowing one to validate whether or not the exploration target is conductive (EM) or not.

5Using the MPP3wifi with a personal computer, a tablet or a smart phone
The most important advantage with the new MPP3wifi is the possibility to control de probe from any
device such as a personal computer, a smart phone or a tablet.
Important: your device must have a wireless connectivity option to be used with the MPP3wifi. If it
is not the case, a USB WLAN adapter can be connected to your device. Also, the MPP application
may not work on old OS versions.
The MPP3wifi probe emits a Wi-Fi®signal enabling any device with a web browser to connect to the
MPP3wifi web application. Internet access is therefore not needed. If using a smart phone in a remote
environment, it is recommended to set it to Plane mode with Wi-Fi manually enabled to disable the
roaming fees.
The MPP3wifi application is a web interface available at this IP address: 192.168.1.115.
The web application is compatible with most of the web browser: Explorer, Chrome, Mozilla, Firefox
and Safari. The MPP3wifi application is not compatible with Windows Mobile or Windows
Embedded Handheld. The recorded data are saved in the MPP3wifi probe itself. It is possible to read
and record the data using one device and download the saved files with another device later.
5.1 Connecting your device to the MPP3wifi web application
1. Power up your MPP probe.
2. Open the Network Connection manager of your device. Select the MPP network
(corresponding to the serial number of your MPP probe).

8. Main screen
The Main screen is the main control center of the MPP3wifi web application. It contains the Control
bar (1), the Readings section (2), the Settings menu (3), the Toolbar (4) and the Status bar (5).
Several times per second, the probe measures and displays three (3) 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. It decreases with the distance
between the probe and the sample.
SCPT 0.001 SI: Magnetic susceptibility is a constant (x10-3). SI = International system of units. Its value
increases with the quantity of magnetite in the sample and decreases with the distance between the
probe and the sample. It is important to note that, with or without the presence of a conductor, the
MPP3wifi probe will measure the magnetic susceptibility value at all times.
COND MHOS/M: Conductivity measured in MHOS/M. It is independent on the quantity of conductive
material in the sample (HF Response) and independent on the distance between the probe and the
sample.
