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.
||Apparent resistivity, resistance, induced polarization (IP),
||Max 30 nV, depends on voltage level
||4 digits in engineering notation.
||1mA - 1.2A continuous
||800 Vp-p, actual electrode voltage depends on transmitted current
and ground resistivity.
|Input gain ranging
||Automatic, always uses full dynamic range of receiver.
||Max 10 V
||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
|IP current transmission
||ON+, OFF, ON-, OFF
|IP cycle times
||1 s, 2 s, 4 s and 8 s
||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
||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.
||Better than 100 dB at f>20 Hz
Better than 120 dB at power line frequencies (16 2/3, 20, 50 & 60 Hz)
||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
||Calibration is done digitally by the microprocessor based on
correction values stored in memory.
||Resistance, Schlumberger, Wenner, dipole-dipole, pole-dipole and
||Stored in re-programmable flash memory. Updated versions can be
downloaded from our web site and stored in the flash memory.
||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.
||Resistivity mode 70.000 readings, Resistivity/IP mode 25.000
||RS-232C channel available to dump data from instrument to a
Windows type computer on user command.
||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
These files are ASCII files and can be created using a regular text
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.

||12/24 V DC external power, connector on front panel.
Maximum power output is increased when using 24V supply.
