True RMS Multimeter (220-0175) Features Faxback Doc. # 8223 This Micronta True RMS, Multimeter is a portable 3 2/3-digit, meter ideally suited for field, lab, shop, bench, and home use. It makes true RMS measurements, a feature you normally find only in the most expansive test instruments, so AC measurements are as accurate as possible. Here are some features that make your meter a real pro. True RMS Operation-gives a more accurate reading for non-sine wave AC measurements. Transistor-Check Function-measures the gain (hfe) of small-signal, bipolar transistors and identifies pin-out and type. Capacitor-Check Function-measures the capacitance of low-voltage capacitors. Frequency Counter-measures frequencies up to 4 MHz. One-Finger Function Selector-makes it easy to use your meter when you have one hand free. Bar Graph Display-makes nulls, peaks, and trends more apparent. Min/Max Memory Function-stores the minimum and maximum measurements of a changing input. Volts or dBm Voltage Display-lets you select the unit of measure that suits your application. Data-Hold Function-freezes the display so you can keep the reading on the display even after your disconnect the probes. Relative-Measurement Function-shows the difference between a stored measurement and a new measurement. Continuity Function-quickly checks the continuity of wires or traces. Full Auto-Polarity Operation-protects your meter and gives valid measurements when you connect the leads in reverse polarity. Diode-Check Function-safety checks semiconductors for open, shorted, or normal junctions. Fully Auto-Ranging-makes your meter easier and safer to use by letting you concentrate on the probes, yet lets you manually set the range for situations where you know what values to expect. UL Listed-passes the stringent tests required by Underwriting 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). (RLR-10/01/93)
