LCD Digital Multimeter (220-0185A) Care and Maintenance Faxback Doc. # 16939 The MICRONTA LCD DIGITAL MULTIMETER is an example of superior design and craftsmanship, and should be treated with care. The suggestions below will help you enjoy this product for many years. Keep it dry. If water should get on it, wipe it off. Water contains minerals that can corrode electronic circuits. Do not store in hot areas. High temperatures can shorten the life of electronic devices, damage batteries, and warp or melt certain plastics. Do not drop it. This might cause permanent damage. The circuit boards and case can be broken. Do not use or store in dusty, dirty areas. This will cause premature wear of moving parts. Do not use harsh chemicals, cleaning solvents, or strong detergents to clean it. Wipe it with a soft cloth dampened in a mild soap-and- water solution. Be sure batteries are the correct type - do not use general purpose batteries if alkaline batteries are recommended. Remove old, weak, batteries - they can leak chemicals that damage electronic circuits. If the unit is not working properly, take it to your local Radio Shack. The personnel there will assist you and, if necessary, arrange service. A WORD ABOUT SAFETY Every precaution has been taken in the design of the meter to ensure that it is as safe s we can make it. However, safe operation depends on you, the operator. We recommend that you follow these simple safety rules: 1. Never apply voltages to the meter that exceed the limits given in the specifications. Never apply more than 1000V DC or 750V RMS AC between input jacks and/or ground. 2. Use extreme caution when working with voltages above 100V. Always disconnect power from the circuit being measured before connecting test leads to high-voltage points. 3. Never connect to a source of voltage when the "Kohn or "Diode Check" function is selected. 4. Always discharge filter capacitors before attaching test leads to a power supply. 5. Battery and/or fuse replacements should only be performed after the test leads have been disconnected and POWER is OFF. 6. Never operate unless the battery cover is in place and fully closed. 7. Since many AC-DC sets have a potentially "hot" chassis, be sure that the top of your workbench and the floor underneath it are made of non- conductive materials. The MICRONTA digital multimeter comes to you fully calibrated and tested. Under normal use, no further adjustment should be necessary. In case the meter should require repair, do NOT try to adjust yourself; bring it to your nearest Radio Shack store. SERVICE BY UNAUTHORIZED PERSONNEL WILL VOID THE WARRANTY.
