Meter maintenance

Never unscrew the two halves of the housing!
The meter does not require any maintenance other than occasional wipe with a damp
cloth and the replacement of depleted batteries.
The housing is made of acrylonitrile butadiene styrene (ABS). This material is attacked
by some organic solvents, such as toluene, xylene and methyl ethyl ketone (MEK). Any
spillage should be immediately wiped off.
