Range Doubler AutoTester (220-0214) Features Faxback Doc. # 8247 This high-sensitivity MICRONTA Multitester is designed to measure AC and DC voltages, DC current and resistance with accuracy and ease. The range doubler switch (V-A/2 - V-ohms-A) effectively doubles the number of AC and DC scales available. This means you can obtain meter reading in the upper half of the scale, resulting in more accuracy. The lowest DC ranges-125mV and 25microA-are great for solid state circuit work. The sensitive 18microA meter movement with 4-1/2" face and mirrored scale makes accurate reading a simple matter. The meter scale are in three colors for rapid identification. The meter circuit incorporates diodes and a fuse to protest the delicate meter movement and other internal parts in case of short-term inadvertent overload or improper function selection. A special audible continuity function has been incorporated. When using this function, a built-in buzzer will sound when the circuit continuity is approximately 300 ohms or less. The large, single-knob range/function control is easy to use and read. An off position to ensure meter protection during transit by shunting the meter movement. (RLR-10/04/93)
