7. Display and Controls
For the LF232 converter, the measured value can be displayed and the parameters can be checked or
set using the LCD display and operation switches.
The operation switches are non-contact type (infrared method) and can be operated without opening
the converter cover (operable also while the cover is opened).
Observe the following precautions when you open the converter cover:
• Do not allow the converter exposed to rain and wind.
Adjustment in the rain may cause damage to the parts and may cause electric
shock and it is very dangerous.
In addition, if wind-blown dust enters the electronic circuits in the converter,
this may cause malfunction of the converter.
• Do not open the converter cover under high humidity condition
Opening the converter cover under high humidity condition can cause
deterioration of system accuracy or cause damage to the flowmeter parts.
