1 Introduction
The SCIP (Sample Core I.P.) tester is an efficient, compact, lightweight and low consumption unit
designed for resistivity measurements.
The SCIP tester uses a field handheld computer to process data acquisition. The operating system
is Windows Embedded Handheld 6.5 Professional.
Characteristics:
 Related to the GDD Rx 8-32: The SCIP acts as a 1 dipole receiver relating DDH Cores to the
resistivity and IP surveys.
 Programmable windows: The SCIP offers twenty fully programmable windows for higher
flexibility in defining the IP decay curve.
 Available Modes: Arithmetic, logarithmic, semi-logarithmic, Cole-Cole and user defined.
 IP display: Chargeability values, Resistivity and IP decay curves are displayed in real time on
a PDA.
 Internal memory: Over 100 000 readings can be stored in the PDA's internal memory. Each
reading includes the full set of measurement parameters. Data are stored on flash type
memory and cannot be lost even if the PDAs battery is totally discharged or absent.
 Transmitting mode: Can be used as a low voltage transmitter of 3, 6, 9 or 12V or 0.5, 5, 50 or
500uA.

GDD’s SCIP tester is powered by a rechargeable Li-Ion battery. Here are a few tips for using and
storing the SCIP tester.
Usage
 Use the power supply provided by GDD to charge the SCIP tester battery. If you want to use
another AC charger, make sure that the specifications are the same as those of the AC
charger provided by GDD.
 Do not replace the SCIP internal battery without the authorization and advice of GDD’s
technicians.
 The total operating time of the SCIP tester depends on environmental conditions. Using the
SCIP in very cold weather (-200C to –400C) decreases the operating time. At normal
temperatures (20°C), the operating time is from 10 to 16 hours.
 The power level of the batteries and the charging status appear on the main screen of the
Archer2 PDA when using the SCIP program.
 Use the AC charger as a power supply for working with the SCIP tester when the battery
level is too low.
 There is a protection circuit in the SCIP tester that prevents charging the battery in cold
weather (under 0°C) or in hot weather (over 45°C).
 The SCIP will turn itself off when the battery reaches a critical low level.
Storage
 When storing the SCIP tester for a few days or more, make sure that the battery is fully
charged.
 Store the SCIP tester in a cool, dry place.

5 Important tips for getting good results
The SCIP (Sample Core Induced Polarization) measures geophysical properties of the ore such as
apparent resistivity and chargeability. The SCIP simulates an Induced Polarization survey. The
waveform is ON+, OFF, ON-, OFF. The current flows through the sample and is then switched off.
While the current is flowing through the sample, a resistivity (Rho) is calculated from the ON Time
Voltage. When the current is switched off, the voltage across the sample drops and a decay curve
is measured. The Chargeability (M) is calculated from this DECAY.
Here are a few tips about preparing and measuring your core samples:
Note: It is very important to always use the same methodology and keep the samples under
the same environmental conditions for all measurements of all samples in order to compare
them with each other.
 Soak your core samples in water for a few days before testing them.
It is recommended to soak the samples in water in order to keep their properties as in
the natural environment. The best way to take measurements would be on fresh
samples. If it is not possible, two days of soaking should be sufficient. Note however
that it is not necessary to leave the samples to soak. The important point is to keep the
same measurement conditions for all samples. The values will not necessarily match
with field data but the measured values of a sample compared to another one allows
defining which ones are less resistive and/or more chargeable. You may then correlate
anomalies versus results from the field.
Note: The use of distilled water by osmosis could dilute the natural salts contained in
the samples and falsify the measurement results. In this case, the use of running
water seems an acceptable compromise.
 Remove the excess of water on the core sample before beginning the measuring process.
 Use a saturated copper sulphate solution.
To take a measurement, the sample is fixed between electrodes by using sponges
dipped in copper sulphate solution. Make sure that some copper sulphate crystals are
not dissolved in water to get a saturated solution.
 Before starting the measurement, make sure that the core sample is completely dry on its
surface.
 During the whole measuring process, make sure that the work bench, the core holders and
the rod that fix together the core holders are completely dry.

Instrumentation GDD Inc. 2018-09-18 Page 8
 During the measuring process, wait until the contact resistance becomes stable before
taking a reading. This may take a few minutes.
 Select the most appropriate settings.
Select the most appropriate stack in order to stop the reading when the chargeability
and the resistivity responses are stable. Depending on your sample and contact
resistance, the number of stacks needed to obtain stable values will vary.
We suggest using the same timing and windows than your field IP survey. Otherwise, a
timing of two (2) seconds and arithmetic windows give good results.
 Use the appropriate mode (constant current or constant voltage).
There are two modes of measurement, voltage and current. In order to determine
which one to use, the contact resistance value (Rs) can be a good indication. For a Rs
between 1 kOhm and 24 kOhms both modes are possible. However, we suggest
selecting a constant current for an Rs lower than 1 kOhm and a constant voltage when
Rs is greater than 1 kOhm. In voltage mode make sure that the Vp (mV) is greater than
half of the selected voltage and in current mode make sure that the I (uA) is almost the
same value of the selected current. If there is saturation, the reading may not be
reliable. In that case, try a lower current or a lower voltage.
 For better results, take the average of several readings on each core sample.

6 Quick Start Guide
Important note: Using a finger may still be the preferred option for projected capacitive screen
technology, but we understand a stylus may also be necessary (like when it’s cold). The way you
hold a capacitive stylus really impacts how it works. To register a point, it is like the screen is taking
a sample from which to calculate the position. It then snaps to the closest line on a grid. If you
hold a capacitive stylus at an angle, it registers less area and does not calculate your true position
as well. For best results on a capacitive screen like the Archer2, hold the stylus as perpendicular to
the screen or straight up as you can. In this section, you will see some tips to use the Archer2
keypad to perform some actions of the SCIP program.
1. Place the core sample into the core holders (see Section 7 – How to use Core Holders).
2. Turn the SCIP tester ON using the ON/OFF switch on the front panel.
3. Select the communication mode using the CABLE/WIRELESS switch on the SCIP tester's front
panel. If Cable mode is selected, connect the serial communication cable between the SCIP
(RS-232 connector) and the Archer2 Field PDA.
4. Turn on the Archer2 Field PC with the ON/OFF key.
