Product description
Product parameters
  Reference standard: GB/T17949.1-2000, DL/T475-2006.
 
  Features:
  ● Strong anti-interference ability, self-contained variable frequency power supply module provides measurement output power, frequency can be changed to 45Hz or 55Hz, digital filtering technology is used to effectively avoid various power frequency interference signals on site, achieving high precision, accurate and reliable measurement;
  ● The instrument automatically judges the impedance of the current loop and automatically adjusts the output current value (rated current 5A) of the inter-frequency power supply. The test task can be completed automatically without human intervention.
  ● The instrument can measure the grounding impedance Z, the pure resistance component R and the pure inductance component X of the grounding grid.
