The Simpson Volt-Ohm-Milliammeters 260 Series 6XLP and 6XLPM (hereafter referred to as the 260 s or the Instrument) are identical electrically and mechanically except that the Series 6XLPM is equipped with a mirrored dial to eliminate parallax. 1.1.2 The 260 s are rugged, high performance, battery-operated Volt-Ohm-Milliammeters capable of making a wide variety of electrical measurements simply and accurately. Features are overload protection, conventional and low-power ohms, and a wide range coverage. The cases are made of high-impact (ABS) plastic, and are contemporarily styled. These features, in combination with the extended range coverage (Table 1-1) make these Instruments general-purpose portable or laboratory Instruments. They are well suited to servicing, production, inspection and engineering applications. 1.1.3 The 260 s utilize the Simpson taut-band movement, which is self-shielding. The taut-band suspension provides a high degree of repeatability and is highly resistant to shock or vibration.
