||Apparent resistivity, resistance, induced polarization (IP), battery voltage
||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 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 0.4, 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 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 accuracy.
||Calibration is done digitally by the microprocessor based on correction values stored in memory.
||Resistance, Schlumberger, Wenner, dipole-dipole, pole-dipole and pole-pole.
||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.
||The memory can store more than 79,000 measurements (resistivity mode) and more than 26,000
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 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.
||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
||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.
||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.
