High precision leakage current, duration and ground continuity settings. Allows no load setup of leakage current and test dwell times. Once entered, ground continuity setting, leakage current and test dwell times can be referenced on the front panel display when unit is not testing. Leakage currents can be set from 1-20 mA AC in 0.1mA increments. Dwell times can be set from 1-60 seconds in 1 second increments.
