10.1 Maintenance
WARNING
• Maintenance work must be carried out by the
trained personnel having knowledge of safety
standard and not by operators.
• When opening the cover, wait for more than 10
minutes after turning off the power. Further-
more, opening of the cover must also be
carried out by the trained personnel having
knowledge of safety standard.
IMPORTANT
• As a rule, maintenance of this flowmeter should
be implemented in a maintenance service shop
where the necessary tools are provided.
• The amplifier assembly contains sensitive parts
that may be damaged by static electricity.
Excercise care so as not to directly touch the
electronic parts or circuit patterns on the board,
for example, by preventing static electrification
by using grounded wrist straps when handing
the assembly.
