CARE AND MAINTENANCE
CARING FOR YOUR MULTIMETER
Your Digital Multimeter 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.
- Keep the multimeter dry. If it gets wet, wipe it dry immediately. Liquids can contain minerals that can corrode electronic circuits.
- 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.
- Handle the multimeter gently and carefully. Dropping it can damage the circuit boards and cause and can accuse the multimeter to work improperly.
- When take current measurement, keep the cable at the center of the clamp will get more accurate test result.
- Keep the multimeter away from dust and dirt, which can cause premature wear of parts.
- Wipe the mutimeter with a damp cloth occasionally to keep it looking new. Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the multimeter.
- Use only fresh batteries of the required size and type. Always remove old or weak batteries. They can leak chemicals that destroy electronic circuits.
- Please take out the battery when not using for a long time.
Volt battery replacement
- Ensure the instrument is not connected to any extemal circuit. Set the Rotary switch to "OFF" position and remove the test leads from the terminals.
- Open the cover of the battery cabinet by a screwdriver.
- Replace the old batteries with the same type batteries.
- Close the battery cabinet cover and fasten the screw.
