RECOMMENDATION
Before using this product, makesure that
it is entirely suitable for the environment
in which they are used. Operation of
these instruments in residential areas
could cause unacceptable interferences
to radio and T.V. equipment. The pins at
the end of the sensor are sensitive to
electrostatic discharges. Avoid touching
this metal band at all times. During
operation of instruments ESD wrist
straps should be worn to avoid possible
damage to the sensor by electrostatic
discharge. Any variation introduced
by the user to the supplied equipment
may degrade the instrument EMC
performance. To avoid electrical shock,
do not use the instrument when voltage
at the measurement surface exceed
24VAC or 60VDC. To avoid damages or
burns, do not perform any measurement
in microwave ovens.
