STING R1 Earth Resistivity Meter

Sting R1

STING R1 earth resistivity meter.

The STING R1 is a state-of-the-art portable earth resistsivity meter with memory storage of readings and user defined measure cycles. It provides the highest accuracy and lowest noise levels in the industry.

Key Benefits

  • Field proven 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 Swift Smart Electrodes, no need for a PC in the field!

Technical Specifications:

Measurement modes Apparent resistivity, resistance, voltage, battery voltage
Built-in methods Schlumberger, Wenner, Dipole-Dipole, Pole-Dipole, Pole-Pole, Mise-a-la-Masse, Resistance, SP-grad, SP-abs, User (see below)
User methods Custom arrays and Swift measure sequences can be designed and loaded into the Sting memory for later execution in the field. Loading software delivered with the Swift system. Design software available as add-on options.
Smart electrodes Directly controls Swift Smart Electrodes. Total automation of the measure sequence for a large array of electrodes possible.
Measurement ranges 400 kohms to 0.1 milliohm (resistance), 0-500 V full scale autoranging (voltage)
Measuring resolution max 30 nV, depends on voltage level
Screen resolution 4 digits in engineering notation.
Output current 1-2-5-10-20-50-100-200-500 mA
Output voltage The user can switch between high and low voltage limit for the transmitter (800 Vp-p or 320 Vp-p voltage limit). Actual electrode voltage depends on transmitted current and ground resistivity. Instrument always starts up in low voltage setting for safety.
Input gain ranging Automatic, always uses full dynamic range of receiver.
Input impedance >20 Mohms
Input voltage Max 500 V
SP compensation Automatic cancellation of SP voltages during resistivity measurement. Constant and linearly varying SP cancels completely.
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.
Cycle time 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 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. The correction values are found in final production testing and are also established during later periodical recommended yearly checks at authorized service centers.
Data storage Full resolution reading average and error are stored along with user entered coordinates and time of day for each measurement. Storage is automatic
Memory capacity Over 3000 measuring points can be stored in the internal memory.
Data transmission RS-232C channel available to dump data from instrument to PC computer on user command.Also used to program Sting for user defined measure cycles.PC programs supplied with instrument.
Communication setting 4800 baud, 8 data bits, no parity, 1 stop bit
User controls 20 key tactile, weather proof keyboard with numeric entry keys and function keys.
LCD Display Alphanumeric display (4 lines x 20 characters). Used for display of results and menus. Night light by LED backlight panel available on switch operation.
Connectors 4 banana plug pole screws for current and potential electrodes.
10-pole KPT connector for external power, charge, RS-232 and remote trig connections
Power supply 12 V, 4 Ah NiCd rechargeable snap-on battery. External power connector on front panel, the instrument automatically selects external battery if present.
Operating time Depends on conditions. At 20 mA output current and 10 kohm electrode resistance more than 2000 cycles are available from a fully charged battery pack.
Battery charger Dual stage charger with switchable input (115/230 V AC @ 50/60 cycles).
Dimensions Width 112 mm (4.4"), length 293 mm (11.54") and height 308 mm (112.11").
Weight 6.6 kg (14.5 lb) including snap-on battery pack.
