Manual Ranging Multimeter (220-0181A) Features Faxback Doc. # 7170 This Radio Shack Manual Ranging Digital Multimeter is a portable, 3 2/3-digit meter ideal for field, lab, shop, bench, and home use. It uses the latest IC and display technology to achieve the lowest possible component count. The true RMS converter is built into a single multimeter chip. These features make the meter easy to use and ensure reliable, accurate, stable, and rugged operation. The meter also includes these features: LCD Bargraph Display - makes nulls, peaks, and trends more apparent. Transistor-Check Function - measures the gain (hFE) of small-signal bipolar transistors. Data-Hold Function - freezes the display so you can view the reading even after you disconnect the leads. Continuity Function - quickly checks the continuity of wires or traces. True RMS Operation - gives a more accurate reading for son-sine wave AC measurements. Full Auto-Polarity Operation - protects your meter and gives valid measurements when you connect the leads in reverse polarity. Effective Overload and Transient Protection - covers all ranges except the DC/AC 10A range. Diode-Check Function - safely checks semiconductors for open, shorted, or normal junctions. UL Listed - passes the stringent tests required by Underwriters Laboratories for safety. Cautions: Completely read this manual before you use the meter. If you are not familiar with meters and testing procedures, we suggest that you obtain and read a book about the subject, such as "Using Your Meter (Radio Shack Cat. No. 62-2039). (br/all-7/18/94)
