NOTE
The test is terminated and the unit does not shift to the READY state until the
DANGER
lamp goes out. Furthermore, all key operations are invalid until the unit
returns to the READY state.
4.6 About the Auto Discharge Function
When measuring a test object that contains a capacity component, the load
continues to discharge during insulation resistance measurement and this
may cause electric shocks.
This unit is equipped with a function that discharges the remaining load
upon termination of insulation resistance tests. (Discharge resistance: 0.8
MΩ)
The unit automatically switches to the internal discharge circuit upon
termination of a test and the load is discharged. (When the
DANGER
lamp is
lit:) If the voltage drops below 50 V, the DANGER lamp goes out. The larger
the capacity, the longer it takes to discharge the test object.
