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. Max 10 V SP compensation Automatic cancellation of SP voltages during resistivity measurement. 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.
