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 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. Since the old cables can be used with SuperSting R1/IP, users of the existing Sting/Swift system wanting to upgrade to the SuperSting can maintain their cable investment.

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.

PRELIMINARY 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 1mA - 1.25 A continuous
Output voltage 800 Vp-p, actual electrode voltage depends on transmitted current and ground resistivity.
Output power 100W
Input gain ranging Automatic, always uses full dynamic range of receiver.
Input impedance >20 MOhm
SP compensation Automatic cancellation of SP voltages during resistivity measurement. Constant and linearly varying SP cancels completely.
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 1 s, 2 s, 4 s 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 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 array co-ordinates.
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. 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.
Memory capacity Resistivity mode 70.000 readings, Resistivity/IP mode 25.000 readings
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 V DC external power, connector on front panel.
Power supply, office Mains operated DC power supply.
Operating time Depends on survey conditions and size of battery used.
Weight 10.9 kg (24 lb), instrument only.
Dimensions Width 184 mm (7.25"), length 406 mm (16") and height 273 mm (10.75").
