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. 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.
Resistivity is calculated using user entered electrode distances.
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. Operating system Stored in re-programmable flash memory. Updated versions can be downloaded from our web site and stored in the flash memory.
