5.5.2 Connecting Equipment for Patient Leakage Current
Measurement
CAUTION
・ The maximum current that can be input into the leakage current
measurement terminals of the 3155 is 25 mA (AC+DC). The input of any
larger current will cause the beeper to sound (when the beeper is turned on),
after which continued input may cause the fuse in the measurement network
to fail. In this case, input must be terminated immediately.
Afterwards, a fuse check is performed automatically upon returning to the
initial screen from the leakage current measurement mode. Therefore, do
not connect anything to leakage current measurement terminal T1. (If
anything is connected, the display may show "Measurement Network Fuse
blown.")
・ The rated capacity of the auxiliary power socket is 1500 VA or less. If this
capacity is exceeded, the auxiliary power outlet circuit breaker will actuate,
and the power supply to the equipment to be measured will be cut off.
(With the 3155-01, the main power switch is turned off.)
・ When power of the equipment to be measured exceeds 1500VA, make the
connection directly to the outlet; do not use the auxiliary power socket.
(When measuring class
equipment, connect the protective earth conductor
of the equipment to be measured to the G terminal of the 3155.)
In this case, the power source polarity and the condition of the equipment to
be measured cannot be set on the 3155.
・ Use an insulating transformer.

1. Plug the power cord of the equipment to be measured into the auxiliary
power socket found on the right side of the 3155.
2. Connect the red 9170 TEST LEAD earth to the leakage current
measurement terminal T2.
3. Touch the red 9170 TEST LEAD to the applied part of the equipment to be
measured.
