• Note that when is pressed in automatic measurement mode, the
instrument generates high voltage without displayed on the screen.
• To avoid the risk of electric shock when a test lead is connected to the T3
terminal, do not touch the part of the test lead that is beyond the finger
barrier. The T3 terminal outputs high voltages.
Do not touch any part of
the test lead beyond the
finger barrier
• If insulation of the signal input/output section and applied part is low due to
the output impedance (22.5 k ± 3 k) of the 110% voltage application func-
tion, a value at or below the allowable value may be detected. Take this into
consideration when setting the allowable value.
• The terminal block is not used for internally powered equipment. However,
power must be supplied to this instrument’s [LINE IN] connector to obtain high
voltage from Terminal T3. Do not connect the equipment under test to an out-
let or the terminal block since power is supplied from an outlet during a 110%
voltage application test.
