Product Features:
1. The structure of the grounding resistance measuring instrument adopts high-strength aluminum alloy as the chassis. The circuit uses a phase-locked
loop synchronous tracking detection method to prevent power frequency and radio frequency interference and is equipped with a switched capacitor
filter to make the instrument have better anti-interference ability
2. Adopt DC / AC conversion technology to change DC to AC low-frequency constant current for easy measurement
3. Allow the auxiliary grounding resistance to change between 0 ～ 1.8KΩ (RC) and 0 ～ 40KΩ (RP), so as not to affect the measurement result
4. The ground resistance measuring instrument does not need to manually adjust the balance. The 3 (1/2) digit LCD display, in addition to measuring
the ground resistance, can also measure low resistance conductor resistance, soil resistivity and AC ground voltage. If the test circuit fails to display
"1" in the header, it means overflow, which is in line with the conventional measurement habits
