3. CARE AND MAINTENANCE
3.1. CARING FOR YOUR MULTIMETER
Your Digital MultiMate is an example of superior design and craftsmanship. The following
suggestions will help you care for the multimeter so you can enjoy it for years.
1) Keep the multimeter dry. If it gets wet, wipe it dry immediately. Liquids can contain minerals
that can corrode electronic circuits.
2) Use and store the multimeter only in normal temperature environments. Temperature extremes
can shorten the life of electronic devices, damage batteries, and distort or melt plastic parts.
3) Handle the multimeter gently and carefully. Dropping it can damage the circuit boards and case
and can cause the multimeter to work improperly although the holster can provide enough
protection.
4) Keep the multimeter away from dust and dirt, which can cause premature wear of parts.
5) Wipe the multimeter with a damp cloth occasionally to keep it looking new. Do not use harsh
chemicals, cleaning solvents, or strong detergents to clean the multimeter.
6) Use only fresh batteries of the required size and type. Always remove old or weak batteries.
They can leak chemicals that destroy electronic circuits.
