Recommendations for Users

Before using these products, make sure that they are entirely suitable for the environment in which they are used.
Operation of these instruments in residential area could cause unacceptable interferences to radio and TV
equipments, requiring the operator to take all necessary steps to correct interferences.
The metal band at the end of the sensor is sensitive to electrostatic discharges. Avoid touching this metal
band at all times. During calibration of instruments, ESD wrist straps should be worn to avoid possible
damage to the sensor by electrostatic discharge. Use plastic beakers to minimize any EMC interferences.
Any variation introduced by the user to the supplied equipment may degrade the instruments' EMC
performance.
To avoid electrical shock, do not use these instruments when voltages at the measurement surface exceed 24
Vac or 60 Vdc.

To avoid damages or burns, do not perform any measurement in microwave ovens.
