Page 44: Setting The Lower-Limit Value For Judgment
The lower-limit for the current value or resistance value is set as the reference for pass/fail judgment. When the measured current value or resistance value is below the reference value, a fail judgment is determined for the test target. If a pass/fail judgment is not to be performed based on the lower-limit value for a DCW test, the test lower-limit value can be set to off. In case of a DCW test, setting a lower-limit value slightly less than the leakage current specific to the test target can be used as a simplified contact check. It is also useful for detecting disconnected test leads and test target problems. HIOKI ST5680A961-00...

Page 47: Setting The Data Maintaining Function During Auto-Ranging
• When the data maintaining function during auto-ranging is set to on When the test is completed while the range switches, the pass/fail is judged using the last measured value. Since the measured value (value immediately before a range movement) is displayed, the instrument cannot determine whether a range movement is being performed. For example, even when the insulation resistance value drops due to dielectric breakdown immediately before the test end time during the insulation resistance test, the measured value during dielectric breakdown is not determined if the test ends during the range movement.
