Micronta Pocket Autorange Digital Multimeter (220-0169) Care and Maintenance Faxback Doc. # 17515 Your Micronta Multimeter is an example of superior design and craftsmanship. The following suggestions will help you care for the meter so that you can enjoy it for years. Keep the meter dry. If it does get wet, wipe it dry immediately. Liquids might contain minerals that can corrode the electric circuits. Use and store the meter only in normal temperature environments. Temperature extremes can shorten the life of electronic devises, damage batteries, and distort or melt plastic parts. Handle the meter gently and carefully. Dropping it can damage the circuit boards and cause it to work improperly. Keep the meter away from dust and dirt, which can cause premature wear of parts. Wipe the meter with a dampened cloth occasionally to keep the meter looking new. Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the meter. Use only fresh batteries of the recommended size and type. Always remove old or weak batteries. They can leak chemicals that can destroy electronic circuits. Modifying or tampering with the meter's internal components can cause a malfunction and might invalidate its warranty. If your meter is not performing as it should, take it to your local Radio Shack store so that our personnel can assist and arrange for service, if needed. (/all-11/29/95)
