• Keep the gauge dry. Precipitation and all types of
liquids or moisture can contain minerals that will
corrode electronic circuits. If your tester does get wet,
remove the battery, and allow the tester to dry
completely before replacing it.
• Do not use, store or expose the gauge in dusty and
dirty areas. Its moving parts and electronic
components can be damaged.
• Do not use, store or expose the gauge in hot areas.
High temperatures can damage or shorten the life of
tester, damage batteries, and warp or melt certain
plastics.
• Do not use, store or expose the gauge in cold areas.
When the tester returns to its normal temperature,
moisture can form inside the tester and damage
electronic circuit boards.
• Do not attempt to open the gauge other than as
instructed in this handbook.
• Do not drop, knock, or shake the gauge. Rough
handling might break internal circuit boards and fine
mechanics.
• Do not use harsh chemicals, cleaning solvents, or
strong detergents to clean the gauge.
• Do not paint the gauge. Paint can clog the moving
parts and prevent proper operation.
