Manual Ranging Multimeter (220-0181A) Safety Faxback Doc. # 7172 We have taken every precaution in designing this meter to ensure that it is as safe as we can make it. But, safe operation depends on you, the operator. We recommend you follow these simple safety rules: 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. Use extreme caution when you work with voltages above 40V. Always disconnect power from the circuit you are measuring before you connect test leads to high-voltage points. Never connect test leads to a source of voltage when you select the diode, resistance, continuity, current, capacitance, or hFE functions. Always discharge filter capacitors in the power supply of the circuit under test before you attach test leads. Always turn off the meter's power and disconnect the test leads before you replace the batteries or fuses. Never operate the meter unless the battery cover is in place and fully closed. Because many AC/DC sets have a potentially hot chassis, be sure the top of your workbench and the floor underneath it are made of non-conductive materials. The multimeter is fully calibrated and tested. Under normal use, no further adjustment is necessary. If the meter does require adjusting, do not try to adjust it yourself. Take it to your nearest Radio Shack store. Service by unauthorized personnel voids the warranty. WARNING: USE EXTREME CAUTION IN 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. (br/all-7/18/94)
