1. Introduction

The highly sensiti e GDD IP Recei er models GRx8-32 is a compact unit designed for high

producti ity resisti ity and time-domain induced polarization (IP) sur eys in mineral exploration,

groundwater exploration, geotechnical in estigations and other related fields. It features high

capabilities allowing it to work in any field conditions. It can be configured for multi-pole or multi-

dipole reception. The recei er uses a rugged field PC to process data acquisition and the software

can easily be updated ia internet.

Characteristics:

•Reception poles/dipoles: 8 poles/dipoles, expandable to 32, for dipole-dipole, pole-dipole

or pole-pole arrays.

•Programmable windows: The GRx8-32 offers twenty fully programmable windows for

higher flexibility in defining the IP decay cur e.

•User modes available: Arithmetic, logarithmic, semi-logarithmic, Cole-Cole and user

defined.

•IP display: Chargeability alues, Apparent Resisti ity, IP decay cur es and pseudosections

can be displayed in real time thanks to the TFT VGA screen. Before data acquisition, the

GRx8-32 can be used as a one channel graphic display for monitoring the noise le el and

checking the primary oltage wa eform through a continuous display process.

•Internal memory: Capacity to store up to 64 000 readings for 8 poles/dipoles, memory

expandable to 512 000 readings on the PDA model. Each reading includes the full set of

parameters characterizing measurements. Data is stored on flash type memory that does

not require any lithium battery for safeguard purposes.

•Full wave data with IP Post-Processing software: The GRx8-32 records and sa es the full

wa e data (*.mem file). This raw data can be imported, isualized and processed using

GDD's IP Post-Processing software.

3. Receiver Components

The GRx8-32 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 Allegro

and the GRx8-32.

B - CABLE/WIRELESS switch

This switch is used to select CABLE (RS-232) or WIRELESS (Bluetooth) communication with

the PDA. The red light indicates that the switch is in the WIRELESS position.

C - HARDWARE connector - 15 pin programming port

This connector is used to update the CPU and PLD software.

D - GPS Connector

This connector is used to connect an external GPS antenna (SMA).

Instrumentation GDD Inc. 2017-12-14 Page 9

E - ON/OFF/SELF-TEST switch

This switch is used to turn the GRx8-32 ON or to perform a self-test. The red light indicates

that the GRx8-32 is ON or in the SELF-TEST position.

F - INTERNAL/EXTERNAL BATTERY switch

This switch is used to select the internal batteries or the external battery pack, pro ided by

GDD.

G - CHARGER connector

This connector is used to charge the recei er batteries. The Internal Battery / External

Battery (F) switch must be on Internal battery.

H - R1 to R4 terminals

In pole configuration, the reference terminals (R1 to R4) are the infinite electrodes. In dipole

configuration, the reference terminal is the first electrode in differential with the second

electrode.

I - NUMBERED terminals

These terminals are referenced to the Ref terminal (Ref is infinity in pole configuration). In

dipole configuration, the numbered terminals are differential terminals.

J - SELF-TEST terminal

This terminal is used to perform a self-test.

Instrumentation GDD Inc. 2017-12-14 Page 10

K - RS-232 external Connector

This connector is used to connect the rugged serial communication cable (Amphenol

connector), which allows communication between the Allegro

and the GRx8-32 recei er.

L - Input signal connector

This connector is used to connect the wires coming from the

electrodes to the recei er channels to keep the Pelican case closed

while taking the readings. A cable mount connector (41 pos.) is

included with the recei er accessories and can be used with the

instrument.

M - External battery connector

This connector is used to connect the external battery pack. The Internal/External battery

switch (F) must be on External battery position.
