| Measurement modes |
Apparent resistivity, resistance, 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 - 1.2A continuous |
| Output voltage |
800 Vp-p, actual electrode voltage depends on transmitted current and ground resistivity. |
| Output power |
200W |
| Input channels |
Eight channels. |
| Input gain ranging |
Automatic, always uses full dynamic range of receiver. |
| Input impedance |
>20 Mohms |
| Input voltage |
Max 10 V |
| SP compensation |
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 |
| 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 0.4, 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 resistance (dV/I) and
apparent resistivity (ohmm or ohmft). Resistivity is
calculated using user entered electrode distances. |
| 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. Updated 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 |
The memory can store more than 79,000 measurements (resistivity mode) and more than 26,000
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 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 |
12/24 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. |
| Operating time |
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. |
| Weight |
10.2 kg (22.5 lb), instrument only. |
| Dimensions |
Width 184 mm (7.25"), length 406 mm (16") and height 273 mm (10.75"). |
