  If your Hioki Test Equipment loses power while measuring insulation resistance, there are several potential causes: * The battery power might be low, in which case you should replace it with a new one. * The battery pack may need charging; ensure it is fully charged. * The GUARD terminal might be short-circuited with the test lead connected to the + terminal. Verify the connection to the test lead clips.
