3.2.4
Automatic Discharge Function
• When insulation resistance with a capaci-
tance component is measured, this com-
ponent remains charged with a high-
voltage equivalent to the test voltage,
which is dangerous.
• This tester automatically discharges
remaining electric charge using the inter-
nal circuit after measurement.
• Make sure that the test leads are connected
to the measured object when pressing the
key to stop measurement.
• Discharging stops when the residual volt-
age falls below 10 V. The discharge time
varies depending on the capacitance.
After the voltage has been decreased by
the tester’s automatic discharge function,
the voltage in the measurement area may
rise again due to the remaining charge in
the capacitor C

shown in the diagram in
section 3.2.6. Take great care when touch-
ing the object under test.
