Range Doubler Multitester (220-0215) Features Faxback Doc. # 6536 The Radio Shack Range Doubler Multitester is a high-sensitivity analog multitester, ideally suited for field, lab, shop and home applications. These features make the multitester easy to use and ensure accurate and reliable operation. Range Doubler Switch - effectively doubles the number of available AC and DC scales for greater accuracy. Low DC Ranges - 125 mV and 25 microA - great for solid state work. Sensitive 18 microA- Meter Movement - simplifies accurate reading with 4 1/2-Inch Face and Mirrored Scale Built-In Diodes and Fuse - protect meter movement and other internal parts in case of improper function selection. Audible Continuity Function - built-in buzzer sounds when there is continuity. Carrying Handle - can be flipped to the back to support the meter at an easy-to- read angle. Note: You need one 9-volt and one 1.5-volt AA battery (not included) to operate this multitester. Warning: USE EXTREME CAUTION IN THE USE OF THIS DEVICE. IMPROPER USE OF THIS DEVICE CAN RESULT IN INJURY OR DEATH. FOLLOW ALL SAFEGUARDS SUGGESTED IN THIS OWNER'S MANUAL IN ADDITION TO NORMAL SAFETY PRECAUTIONS IN DEALING WITH ELECTRICAL CIRCUITS. DO NOT USE THIS DEVICE IF YOU ARE UNFAMILIAR WITH ELECTRICAL CIRCUITS AND TESTING PROCEDURES. NOT FOR COMMERCIAL OR INDUSTRIAL USE. A WORD ABOUT SAFETY We have taken every precaution in designing and manufacturing this meter to ensure that it is as safe as we can make it. But safe operation depends on you, the operator. We recommend that you follow these simple safety rules. Use extreme caution when working with voltages above 30 Volts AC or 60 Volts DC. Always disconnect power from the circuit you are measuring before you connect the test probes to high-voltage points. Never connect the test probes to a source of voltage when you select resistance, continuity, or current measurement functions. Always turn off the meter's power and disconnect the test probes before you replace the batteries or fuse. Never operate the meter unless the back cover is in place and fully closed. Because some AC/DC sets have a hot chassis, be sure that the top of your work bench and the floor underneath it are made of non- conductive materials. The meter is fully calibrated and tested. Under normal use, no further adjustment should be necessary. If the meter should require repair, do not try to adjust it yourself. Take it to your local Radio Shack store. Service by unauthorized personnel voids the warranty. (BR/all-07/11/94)
