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. 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.
Memory capacity More than 3000 measuring points can be stored in internal memory. PC programs supplied with instrument. 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. Connectors 4 banana plug pole screws for current and potential electrodes.
