SuperSting R8 IP
8 channel Memory Earth Resistivity and IP Meter

Sting R8

The SuperSting R8 IP is a state-of-the-art multi-channel portable memory earth resistsivity meter with memory storage of readings and user defined measure cycles. It provides the highest accuracy and lowest noise levels in the industry.
This new instrument revolutionizes the field of resistivity imaging surveys by its capability to simultaneously measure up to 8 channels using a high power transmitter so that field data production can reach previously unheard of speeds.
With the high power transmitter good data can be recorded in difficult locations where time-consuming stacking was the only alternative before.
SuperSting R8 IP uses the new Multi-channel Swift Dual Mode Automatic Multi-electrode cable (patent 6,404,203) based on the successful design used in our single-channel cables. With this new cable it is now possible to efficiently record 3D data and use a virtually unlimited quantity of electrodes in a single layout. The electrode address is now a 16 bit number which sets range at about 65000 electrodes!
The controller for this new cable is completely built into the SuperSting R8 IP main instrument so there are no extra boxes to carry and connect in the field.

Key Benefits

  • 8 channel simultaneous measure capability, cuts field time dramatically!
  • High power transmitter. Can use both 12V and 24V batteries for added power.
  • Field adapted rugged construction. Built to last in real conditions.
  • Easy to use menu driven system.
  • The best accuracy and noise performance in the industry!
  • Large capacity internal memory for storage of measurement results.
  • User programmed measure cycles can be loaded into memory from a PC and later executed in the field.
  • Directly controls the Multi-Channel Swift Dual Mode Automatic Multi-electrode system (patent 6,404,203)!
  • Induced Polarization mode records 6 individual IP chargeability windows.

PRELIMINARY TECHNICAL SPECIFICATION:

Measurement modes Apparent resistivity, resistance, induced polarization (IP), battery voltage
Measurement range +/- 10V
Measuring resolution Max 30 nV, depends on voltage level
Screen resolution 4 digits in engineering notation.
Output current 1mA - 1.2A continuous
Output voltage 800 Vp-p, actual electrode voltage depends on transmitted current and ground resistivity.
Output power 200W
Input channels Eight channels.
Input gain ranging Automatic, always uses full dynamic range of receiver.
Input impedance >20 Mohms
Input voltage Max 10 V
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 chargeabilitiy (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 0.4, 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 & 60 Hz)
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 Resistance, Schlumberger, Wenner, dipole-dipole, pole-dipole and pole-pole.
Operating system Stored in re-programmable flash memory. Updated versions can be downloaded from our web site 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.
Memory capacity The memory can store more than 79,000 measurements (resistivity mode) and more than 26,000 measurements in combined resistivity/IP mode
Data transmission 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, Wenner and Schlumberger surveys including roll-along surveys completely automatic with the Swift Dual Mode Automatic Multi-electrode system (patent 6,404,203).
The SuperSting can run any other array by using user programmed command files.
These files are ASCII files and can be created using a regular text editor.
The command files are downloaded to the SuperSting RAM memory and can at any time be recalled and run. Therefore there is no need for a fragile computer in the field.
User controls 20 key tactile, weather proof keyboard with numeric entry keys and function keys.
On/Off switch
Measure button, integrated within main keyboard.
LCD night light switch (push to illuminate).
Display Graphics LCD display (16 lines x 30 characters) with night light.
Power supply, field 12/24 V DC external power, connector on front panel.
Maximum power output is increased when using 24V supply.
Power supply, office Mains operated DC power supply.
Operating time Depends on survey conditions and size of battery used. With 24V battery usage survey times can be reduced thanks to the higher output power available.
Weight 10.2 kg (22.5 lb), instrument only.
Dimensions Width 184 mm (7.25"), length 406 mm (16") and height 273 mm (10.75").
