Operating instructions
4point light 10W (V 4.58)
! NOTICE
Noise signals
Any type of noise at the measurement frequency will interfere with the measurement.
Acquired data may not be evaluable.
→
Exclude mains interferences
→
Avoid magnetic interferences
→
Avoid measurements in case of wind or rain
→
Ensure mechanical stability of the electrodes
! NOTICE
Noise signals at 10 Hz measurement frequency
In Europe or other countries with 50 Hz mains frequency measurements at 10 Hz
result in strong mains interferences. Mains interferences disturb the measurement
→
Never use 10 Hz in Europe or in any other countries with 50 Hz
mains frequency.
2.2 Intended use
The earth resistivity meter
4point light 10W
is a high precision instrument for
determination of soil resistivity. The electrical resistivity allows determination of the water
content in the soil and of the types of soils and rock.
Applications are:
▪
Groundwater prospecting
▪
Mining
▪
Environmental investigations
▪
Lab measurements
▪
Measurement of Induced Polarization (IP)
▪
Sounding and mapping of archaeological sites
The instrument may not be changed or modified. Please observe the safety instructions!
