More finely graded settings are also possible. When measurement is completed, the unit shows the insulation resistance value, test voltage (setting and actual output), leakage current, DAR, PI, and elapsed time. When measuring insulation resistance, the instrument can be switched to display leakage current. This is possible before, during, and after measurement.
