only when selecting network B and providing equipment with a Type BF or Type CF applied part

(external voltage on a specific F-type applied part)
• 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 T2
terminal, do not touch the part of the test lead that is beyond the finger
barrier. The T2 terminal outputs high voltages.
Do not touch any part of
the test lead beyond the
finger barrier
•
If insulation of the applied part and earth is low due to the output impedance
(22.5 k ±

3 k

) of the 110% voltage application function, a value at or below
the allowable value may be detected. Take this into consideration when set-
ting 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.
•
The enclosure of the equipment under test (internally powered equipment) is
grounded.
