||Apparent resistivity, resistance, self potential (SP), induced polarization (IP), battery voltage.
||Max 30 nV, depends on voltage level.
||4 digits in engineering notation.
|Output current intensity
||1mA - 2000 mA continuous, measured to high accuracy.
||800 Vp-p, actual electrode voltage depends on transmitted current and ground resistivity.
|Input gain ranging
||Automatic, always uses full dynamic range of receiver.
||Automatic cancellation of SP voltages during resistivity measurement. Constant and linearly varying SP
|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.
||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.
||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.
||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.
||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.
||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.
||Stored in re-programmable flash memory. New 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.
||Apparent resistivity (Ohmmeter), current intensity (mAmp) and
measured voltage (mVolt) are displayed and stored in memory for
||The memory can store more than 24,468 measurements (resistivity mode) and 14,966
measurements in combined resistivity/IP mode.
||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 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.
||The instrument has four banana pole screws for connecting current
and potential electrodes during manual resistivity measurements.
||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).
||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.
||Depends on survey conditions and size of battery used. Internal circuitry in auto mode adjusts current to save energy.
||-5 to +50°C.
