• Measurement conditions
Circuit tester to be used: HIOKI3030
• Permissible error of resistance is ±20%
Note) 1 HIOKI HiTESTER MODEL 3030 was used for this measurement. Using another tester can result in an
abnormal resistance value and an inaccurate test.
2 Disconnect all connections and measure as a separate unit.
3 Any movement of the tester needle is displayed as "ON" and indicates that it is conductive.
4 "CON" display is a characteristic of the condenser in which the needle moves once and then returns to
stabilize at the value shown in ( ).

varies widely depending on the type and state of the tester (such as the internal power supply) and the
range.
