Electrical supply
Although fully tested before shipping it is advisable
that you have your viscometer checked by a
competent electrical contractor before use.
Electrical Power Supply Cord
Do NOT replace the detachable MAINS supply
cords with an inadequately RATED cord. An
adequately rated cord should comply with the
following:
UK - IEC (C13)/US-IEC (C13)
HO5VV-F 3G 1.0mm² Cores
Fitted with 5amp fuse (UK only)
GTSA-3 N1458
The unit must not be operated with
the hinged front cover up.
Never operate the equipment with any of the
cover(s) raised up or removed.
Cleaning the viscometer with water
could increase the hazard of an
electric shock.
Only trained operators should clean the
viscometer.
Cleaning fluid should never be used near the
electrical components of the system especially
those behind the lift-up hinged front cover of the
viscometer. It is perfectly safe to clean the stage
and drive mechanism underneath
– normally done
as part of the monthly cleaning activities.
If incorrect actions are taken, there
is a risk of electric shock during
maintenance.
Only trained personnel are permitted to maintain or
repair the viscometer.
Before opening any covers always disconnect from
the power supply unless the power is required for
diagnosis.
Circuit boards are used in the
viscometer. They can be damaged
by static electricity.
Touch an earth point immediately before
attempting to handle a circuit board.
Keep any circuit board in an electrostatic bag when
not in use/fitted.
