The Amprobe GP-2 is a datalogging / recording ground tester. The unit automatically applies three testing frequencies for more accurate measurements. Price includes a complete kit with ground rod electrodes, cables, software and communications cables.

  • Measures Earth ground resistance - 3 point (fall of potential) or 2 point tests
  • Automatically calculates resistivity - 4 point test
  • Automatic voltage measurement prevents false measurements
  • Automatically applies three testing frequencies for the most accurate readings
  • Test leads, auxiliary electrodes and software are included for complete instrument
  • Auto ranging
  • 999 internal memory locations to store measurements
  • RS-232 download to a personal computer

Resistively Measurement ρ

 Range (**) Resolution Accuracy (*)
0.6 - 125.6Ωm 0.1Ωm ±2% reading ± 3 Digits
0.125 - 1.256kΩm 0.001Ωm
1.25 - 19.99kΩm 0.01Ωm

Testing Frequency 125Hz/75Hz/41.66Hz
Testing Current 10mA
Open Terminal Measuring Voltage 25Vrms
Waveform of Measuring Voltage Sine Wave
Amperometric circuit The measurement is taken with the stated accuracy if the interfering Voltage is ≤3V, while for interfering voltages between 3 and 30V inclusive, the accuracy decreases progressively; with interfering voltage of about 30V the instrument does not perform the test.
Voltmetric Circuit The measurement is taken if the interfering voltage is ≤3V; in case of higher voltages the instrument does not perform the test.
Interfering Voltage Measurement Range (V) (**) Resolution (V) Accuracy
500 1 ±(2% reading ± 2 Digits)
Additional Notes (*)=If Rρ > 100RE and/or RC > 100RE, Rρ > 50kΩ and/or RC >  50kΩ, if the instrument carries out the test the accuracy of the instrument is ±(10% Reading)
Rρ =  Resistance of the voltage circuit
 
RC= Resistance of the current circuit
