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.
|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.|
|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.
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").|
