For continued protection against electric shock certain parts of this equipment, including the PC
compatible signal interface connections have been designed such that the voltage is limited to a safe
value. In order to maintain this level of protection it is essential that any equipment connected to this
equipment shall have interface connections which are similarly protected.
Assurance must be obtained from the manufacturers and suppliers of such equipment that interfaces
comply with the requirements for SELV circuits in accordance with IEC 1010 (EN 60101).
DO NOT install this equipment at any location less than 400mm above or 400mm below garage floor
level.
DO use this equipment in accordance with the operating procedures.
DO ensure that all connections are made prior to applying voltages to the measurement system and
that the lower voltage terminal connection (closest to ground) is made first and broken last.
DO NOT use this equipment to measure voltages higher than 450V AC peak < 20% duty cycle or
200Vrms max.

CAUTION - This equipment must only be used by trained
personnel.
WARNING – If the VMM is being used in a moving vehicle,
ensure that the VMM and cables do not distract or interfere
with the driver, or form a hazard in any way.
CAUTION - Use of this equipment in a manner not specified
by the manufacturer may impair the protection provided by
this equipment.
CAUTION - Do ensure that only those test probes which are
required by the diagnostic procedure in use are connected
to the VMM while the diagnostic is running and that all test
probes are disconnected after the measurement has been
taken.
