Geo-electric research delivery format and use
Each data unit is completed by a “;”. If certain information is not known (such as who performed the measurement), then only a “;” appears on a line.
Decimals are shown by a point “.”.
Figures that belong together (such as electrode distance, voltage, strength of current and apparent resistance) are separated by a semi-colon “;” and appear on the same line. If a certain value is unknown (such as strength of current), then it is left blank (two consecutive semi-colons).
Gebruikte afkortingen:
| a | Distance between the 2 electrodes that are closest together (usually between the potential electrodes) [m] |
| L/2 | Half of the distance between the outermost electrodes of the measurement set-up [m] |
| V | The measured potential difference [mV] |
| I | The strength of current used [mA] |
| R | The calculated apparent electric resistance [Ohm-m] |
