RECOMMENDATIONS FOR USERS
Before using these products, make sure they are entirely suitable for the
environment in which they are used.
Operation of these instruments in residential areas could cause
unacceptable interferences to radio and TV equipment, requiring the
operator to follow all necessary steps to correct interferences.
The glass bulb at the end of the pH electrode is sensitive to electrostatic
discharges. Avoid touching this glass bulb at all times.
During operation, ESD wrist straps should be worn to avoid possible
damage to the electrode by electrostatic discharges.
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 damage or burns, do not perform any measurement in
microwave ovens.
