Simpson 260 Series 6XLP Analog VOM Volt-Ohm-Milliammeter Overload Protected

Simpson 260 Series 6XLP Analog VOM Volt-Ohm-Milliammeter Overload Protected

The Simpson 260 is one of the most widely recognized analog VOMs (Volt-Ohm-Milliammeters) ever produced. This example is a Series 6XLP, featuring taut band suspension movement and overload protection — two features that set later 260 series models apart from earlier versions. It measures DC and AC voltage, DC current, and resistance across a wide range of scales, all read from a multi-arc analog meter face. The unit uses a portable black case with an integrated carry handle.

Applications

The Simpson 260 has been a staple of electrical and electronics service work since its introduction in the 1930s, and the Series 6XLP represents one of the later, refined iterations — produced from roughly the 1970s through the 1980s. It is used for general-purpose voltage, resistance, and current measurements in industrial maintenance, electronics repair, radio and audio servicing, and electrical troubleshooting. The taut band suspension replaces the traditional pivot-and-jewel movement, making the meter more resistant to shock and reducing friction for more accurate low-level readings. The overload protection helps prevent damage to the movement when excessive voltage or current is applied. The 260 remains popular with technicians who prefer analog meters for tasks like checking diode polarity, observing fluctuating signals, or working on tube-type audio and radio equipment where an analog needle response is easier to interpret than a digital readout. Hobbyists, educators, and vintage electronics collectors also seek out the 260 for its durability, repairability, and long production history.
