SuperSting R1 IP
single channel Memory Earth Resistivity and IP Meter
The SuperSting R1 IP is a state-of-the-art single-channel portable memory earth resistivity
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 is based on technology developed for the famous SuperSting R8/IP multi-channel
instrument. It pushes the performance levels of single channel systems forward by a large step.
With the high power transmitter good data can be recorded in difficult locations where time-consuming
stacking was the only alternative before.
SuperSting R1/IP uses the patented Swift Dual Mode Automatic Multi-electrode cable. For users
of the existing Sting/Swift system wanting to upgrade the instruments their cable investment can be reused
with this new instrument since the old cables can be used also with SuperSting R1/IP.
The controller for the cable is now completely built into the SuperSting R1/IP main instrument so there are
no extra boxes to carry and connect in the field.
Key Benefits
- High power transmitter.
- 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 Swift Dual Mode Automatic Multi-electrode system (patent 6,404,203)!
- Induced Polarization mode records 6 individual IP chargeability windows.
- Manual measurements are available via four banana pole screws on the top of the instrument for connecting current and potential electrodes. Manual measurement array types include: Resistance, Schlumberger, Wenner, Dipole-dipole, Pole-dipole, Pole-pole, SP-Absolute, and SP-Gradient.
TECHNICAL SPECIFICATION:
| Measurement modes | Apparent resistivity, resistance, self potential (SP), 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 intensity | 1mA - 2000 mA continuous, measured to high accuracy. |
| Output voltage | 800 Vp-p, actual electrode voltage depends on transmitted current and ground resistivity. |
| Output power | 200W. |
| Input gain ranging | Automatic, always uses full dynamic range of receiver. |
| Input impedance | >20 Mohms. |
| SP compensation | Automatic cancellation of SP voltages during resistivity measurement. Constant and linearly varying SP cancels completely. |
| 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 0.2, 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 voltage, current and apparent resistivity (Ohmm or Ohmft). Resistivity is calculated using user entered electrode array co-ordinates. |
| Noise suppression | Better than 100 dB at f >20 Hz |
| Powerline noise suppression | Better than 120 dB at power line frequencies (16 2/3, 20, 50 & 60 Hz) for measure 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 manual configurations | Resistance, Schlumberger, Wenner, dipole-dipole, pole-dipole, pole-pole, SP-absolute and SP-gradient. |
| Operating system | Stored in re-programmable flash memory. New 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. |
| Data display | Apparent resistivity (Ohmmeter), current intensity (mAmp) and measured voltage (mVolt) are displayed and stored in memory for each measurement. |
| Memory capacity | The memory can store more than 24,468 measurements (resistivity mode) and 14,966 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 uploaded 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. |
| Manual measurements | The instrument has four banana pole screws for connecting current and potential electrodes during manual resistivity measurements. |
| 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 | 12V or 2x12V DC external power (one or two 12 V batteries), connector on front panel. |
| Power supply, office | Mains operated 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 | -5 to +50°C. |
| Weight | 10.9 kg (24 lb), instrument only. |
| Dimensions | Width 184 mm (7.25"), length 406 mm (16") and height 273 mm (10.75"). |
