NOTE
If the window is visibly worn out, replace it.
Checking the Door Gasket
The measurement unit door utilizes an electrically conductive gasket to
suppress electromagnetic radiation. When the door is opened, check that
the gasket and the opposite contact surfaces are clean. If necessary, use a
wet cloth for cleaning.
Checking the Battery
Check the battery condition annually. If there are any signs of aging,
such as a bulging battery case, white powder, or residue near the battery
vent, leaking electrolyte, or corroded terminals, replace the battery. Lead
acid batteries may age in 3 to 5 years time and result in a rupture and loss
of electrolyte.
NOTE
When disposing of old batteries, be sure to follow local environmental
regulations.
NOTE
In freezing temperatures there is a danger of battery rupture if the battery
is completely discharged. Do not store empty batteries in freezing
temperatures. Replace the battery if signs of mechanical rupture are
observed.
Storage
If the CL31 is stored unpacked for extended periods of time in an
unconditioned area, keep caps on all external connectors. Keep the
measurement unit door closed and also keep a dust cover on the window
during long periods of storage.
Save the container for future transport use. For transportation, the
equipment must be placed and padded into the container in the same way
as initially received.
