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 areas could cause unacceptable interferences to radio and
TV equipment.
The glass bulb at the end of the 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 instrument's EMC
performance.
To avoid electrical shock, do not use these instruments when voltages at the measurement surface
exceed 24VAC or 60VDC.
For HI 8424 and HI 9622: the position of the probes' cable (the pH electrode and the temperature
probe) could effect the measurements. In order to minimize these effects due to external electromag-
netic fields, it is recommended to keep parallel the cables of the two probes and as close as possible
to the instrument.
In particular cases HI 8915 could change its operating mode. In such cases, press any key to return to
normal operating conditions.
In particular cases, HI 8314 and HI 9214 could turn off. In such cases, turn the meters on by pressing
the ON/OFF key.
To avoid damages or burns, do not perform any measurement in microwave ovens.
