5.5 Cleaning
If the instrument is unmounted at the time of cleaning, disconnect the
instrument from the power source. Close and latch the front-panel access
door. Clean outside surfaces with a soft cloth dampened slightly with plain
clean water. Do not use any harsh solvents such as paint thinner or
benzene.
For panel-mounted instruments, clean the front panel as prescribed in
the above paragraph. DO NOT wipe the front panel while the instrument
is controlling your process.
