Perform Hioki resistance test at each HV
joint from HV busbar lead to bolt head
注2x HV joints, The acceptable resistance is between 0.050 mΩ (50 μΩ) and 0.195 mΩ (195 μΩ).If the resistance is greater than 0.195 mΩ (195 μΩ), there is too much resistance in the High Voltage joint. Remove the fastener, clean areas with isopropyl alcohol, install fastener back and test again.If the resistance is lower than 0.050 mΩ (50 μΩ), reposition the probes and measure again.If the resistance is repeatedly between 0.00 mΩ and 0.050 mΩ (50 μΩ), hioki test passed, proceed to next step
