CO
ert gas bottle
trol system test.
2 Battery connec- Voltage supply for the SMT 300 via
tion cable 12 V the vehicle battery 12 V.
(length: 2.5 m)
3 Internal To protect the tester and the ve-
filter drain hicle from contaminated air in the
workshop.

i
Occasional draining of liquid from the internal filter
drain (item 3) is normal. Excessive draining indicates
that the workshop's compressor must be drained
and/or that a separate filter system is needed.
!
If the workshop's compressor is not kept dry, this
can result in contamination of the SMT 300 and the
vehicle to be tested.

Component description

Component Function
UltraTraceUV® The only non-contaminating smoke-gen-
smoke solution erating UV-dye solution approved by
automobile manufacturers. The chem-
ical composition of the solution con-
tains a special dye that is deposited at
the exact location of leakage. One bot-
tle (355 mL) is sufficient for about 300
complete test cycles
Connector cap kit For sealing an intake control system in or-
der to retain smoke in the system, e. g.
mass air flow meter lines, for a correct leak
test.
Smoke diffusor For localizing leakage in the areas
around the doors, windows, sunroof
and luggage compartment.
