5.4 Enclosure Leakage Current Measurement Mode (ME Equipment)
────────────────────────────────────────────────────
NOTE
Insulating transformer
Equipment to be measured
Red 9170 TEST LEAD
Signal input or signal output part
which is not protectively earthed
9195
9196
NOTE
For 110% applied voltage
Make the appropriate output settings for the 9196 APPLY UNIT.
Set the polarity toggle switch and the type toggle switch to match the applied
part type of the equipment to be measured.
POLARITY:
NORMAL or REVERSE
APPLIED PART (TYPE):
B/BF
,
CF
Touch the voltage application probe of the 9196 APPLY UNIT to the signal
input or signal output part which is not protectively earthed of the equipment
to be measured.
Press the voltage application button on the voltage application probe.
The application of voltage is in effect only as long as the button is being
pressed.
110% voltage application is performed under single fault condition, but because
this cannot be set by the 3155, the setting is normal condition.
Because the allowable value setting is quite different from that of conventional
normal condition settings, care is necessary when making this setting.
If the enclosure or any part thereof is made of material with insulating characteristics
If the enclosure or any part thereof is made of material with insulating
characteristics, attach the 9195 ENCLOSURE PROBE to the enclosure at
approximately 0.5 N/cm
2
across the entire surface.
・ When the auxiliary power socket does not fit the power plug of the
equipment to be measured, use the supplied power plug.
・ When testing class 0I or other older models, use (UL1015, AWG #18 or
equivalent) wire to connect the G terminal with the protective earth
terminal of the equipment to be measured.
・ Do not apply 110% voltage if there is any chance that circuitry or other
physical components of the instrument might be damaged.
・ Use wire for connecting the functional earth terminals of an equipment to
be measured, or an F-type applied part to the ground.
・ When the equipment to be measured requires the use a single phase power
source, connect the 3155 between the power source and the single phase
power source, as well as between the single phase power source and the
equipment to be measured.
