Checking the Door Gasket
The door of the measurement unit utilizes an electrically conductive
rubber gasket to suppress electromagnetic radiation. When the door is
opened, check that the gasket and the opposite contact surface is clean.
Use a wet cloth for cleaning if necessary.
Battery Check
Check the battery condition annually. If any signs of aging such as a
bulging battery case, white powder or residue near the battery vent,
leaking electrolyte, or corroded terminals is observed 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.
