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.

3. Batteries
3.1 Supplying power to the probe
It is possible to power the MPP probe using three (3) AA batteries or the wall power supply included
with the MPP set.
*** The use of another power supply than the one provided by GDD could damage the probe.
3.2 Battery level indicator
When the probe is powered with AA batteries, it is important to verify that their capacity is sufficient.
Press and hold the BI button located at the side of the probe to turn on the lights.

3.3 Recharging AA batteries
Simply put the AA batteries in the charger and plug it in the wall using the 120 V plug located at the
back of the charger or another plug adapter. The AA batteries charger is designed to be used at
50/60Hz –120/240V.

4Probe buttons and switches
4.1 On / Off Switch
Turn on the probe with the On / Off toggle switch.
4.2 STAMP and MEM buttons
There are two buttons on the handle of the MPP3wifi probe. These buttons have the same utility as
the STAMP and MEMORY icons of the web application and were designed to facilitate handling. See
Section 11 –Reading Modes for more details.
4.3 BI button
See Section 3.2 –Battery level indicator to know how to use this button.

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).
Refer to the user’s guide of your device to know how to select a network.
