SuperSting™ Wi-Fi

Item

Description

Measurement Modes

Apparent resistivity, resistance, induced polarization (IP), SP, and battery voltage.

Measurement Range

+/- 10Vp-p.

Measuring Resolution

Max 30 nV—depends on voltage level.

Screen Resolution

4 digits in engineering notation.

Transmitter

200W internal transmitter. 5kW, 10kW and 15kW external transmitters also available (see separate brochure).

Output Current

1 - 2000 mA continuous, measured to high accuracy.

Output Voltage

800 Vp-p—actual electrode voltage depends on transmitted current and ground resistivity.

Input Channels

Five models available—8-, 6-, 4-, 2-, or 1-channel.

Input Gain Ranging

Automatic—always uses full dynamic range of receiver.

Input Impedance

>150 MOhm.

SP Compensation

Automatic cancellation of SP voltages during resistivity measurement. Constant and linearly varying SP cancels completely (V/I and IP measurements).

Type Of IP Measurement

Time domain chargeability (M). Six time slots measured and stored in memory.

IP Current Transmission

ON+, OFF, ON-, OFF.

IP Cycle Times

0.5, 1, 2, 4, and 8 s.

Measure Cycles

Running average of measurement displayed after each cycle. Automatic cycle stops when reading errors fall below user set limit or user set max cycles are done.

Resistivity Cycle Times

Basic measure time is 0.2, 0.4, 0.8, 1.2, 3.6, 7.2, or 14.4 s as selected by user via keyboard. Autoranging and commutation adds about 1.4 s.

Signal Processing

Continuous averaging after each complete cycle. Noise errors calculated and displayed as percentage of reading. Reading displayed as resistance (dV/I) and apparent resistivity (ohmm or ohmft). Resistivity is calculated using user-entered electrode distances.

Noise Suppression

• Better than 100 dB at f >20 Hz.

• Better than 120 dB at power line frequencies (16 2/3, 20, 50, and 60 Hz) for measurement cycles of 1.2 s and above.

Total Accuracy

Better than 1% of reading in most cases (lab measurements). Field measurement accuracy depends on ground noise and resistivity.

Instrument will calculate and display running estimate of measuring accuracy.

System Calibration

Calibration is done digitally by the microprocessor based on correction values stored in memory.

Supported Configurations

• In manual mode: Resistance, Schlumberger, Wenner, dipole-dipole, pole-dipole, and pole-pole.

• In automatic mode: Any configuration can be programmed via command file.

Operating System

Stored in reprogrammable flash memory. Updated versions can be downloaded from our website and stored in the flash memory.

Data Storage

Full resolution reading average and error are stored along with user-entered coordinates and time of day for each measurement. Storage is effected automatically in a job-oriented file system.

Data Display

Apparent resistivity (ohmmeter), current intensity (mA), and measured voltage (mV) are displayed and stored in memory for each measurement.

Data can also be displayed on an Android device in real time as bright color pseudosections, IP curves, transmitter/receiver plot, contact resistance measurements, and more.

Memory Capacity

Virtually unlimited data storage in real time on controlling Android device.

The internal SuperSting memory can store more than 79,000 measurements (resistivity mode) and more than 26,000 measurements in combined resistivity/IP mode.

Data Transmission

Data can be instantaneously transferred from the Android device by email or by file transfer from the Android device USB port.

RS-232C channel available to dump data from instrument to a Windows-type computer on user command.

Automatic Multi-Electrodes

The SuperSting is designed to run dipole-dipole, pole-dipole, pole-pole, gradient, Wenner, and Schlumberger surveys including roll-along surveys completely automatic with the patented Dual Mode Automatic Multi-Electrode system (U.S. Patent 6,404,203) or a passive electrode cable system.

The SuperSting can run any other array by using user-programmed command files. These are ASCII files that can be created using a regular text editor. The command files are uploaded to the SuperSting RAM memory and can at any time be recalled and run as a survey.

User Controls

• 20-key-tactile, weatherproof keyboard with numeric entry keys and function keys.

• On/Off switch.

• Measure button integrated within main keyboard.

• LCD night-light switch (push to illuminate).

• Keyboard and LCD are mirrored to an Android™ device using Wi-Fi® technology for easy remote control of the SuperSting.

Display

Graphics LCD display (16 lines x 30 characters) with night-light.

Android mobile phone screen (7”) or 10” Android tablet with bright color AMOLED display.

Power Supply, Field

• 12V or 2x12V DC external power—connector on front panel.

• Optional AC/DC power supply and motor generator.

Power Supply, Office

DC power supply.

Operating Time

Depends on survey conditions and size of battery used. Internal circuitry in auto-mode adjusts current to save energy.

Operating Temperature

-20 to +50°C when controlled by your Android device (phone or tablet). The instrument LCD screen fades out at -5ºC, but the instrument continues to function normally by your Android phone, kept warm in your pocket
