PRELIMINARY EXAMINATION
HI 981411-0 and HI 981411-1 are pH indicators and
controllers with a relay output designed for simplicity of use
in a wide range of applications.
The models are panel-mounted with membrane keypads
on the front panel and an easy-to-read LCD display.
Power supply, wiring and selection are made via the plug-
in terminal blocks on the rear panel. The instruments are
equipped with a BNC socket and accept input from conven-
tional combination pH electrode.
LED indicators on the front panel identify whether the
controller is in set or reading mode, and if dosing device
is activated.

Recommendations for Users
Before using this product, make sure that it is entirely suitable for the
environment in which it is used. Operation of this instrument 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 dis-
charges. 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 this instrument 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.
