    3 SCIP tester components The SCIP tester components are described in this section. A - RS-232 connector - 9 pin serial communication port This connector is used to connect the RS-232 cable between the Archer Field PDA and the SCIP tester. B - CABLE/WIRELESS switch This switch is used to select CABLE (RS-232) or WIRELESS (Bluetooth) communications with the PDA.

  • Page 6: Power

    Power 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.

  • Page 7: Important Tips For Getting Good Results

    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.
  • 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.

  • Page 9: Quick Start Guide

    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.
