Information

The Simpson Volt-Ohm-Milliammeters 260 Series 7 and Series 7M (hereafter referred to as the 260 or as the Instrument), are identical instruments electrically and mechanically, except that the Series 7M is equipped with a mirrored dial to eliminate parallax (Figures 1-1 and 1-2). The 260 Series 7 is a rugged, accurate, compact, easy-to-use instrument. The Instrument can be used to make accurate measurements of AC and DC voltage, direct current, resistance, decibels, and Output Voltage. The Output Voltage function is used for measuring the AC component of a mixture of AC and DC voltage. This occurs primarily in Amplifier circuits. 1.1.2 New Features in the 260-7 and 7M are: • New connectors between the Instrument and the test leads which eliminates a shock hazard in the event a connector is inadvertently pulled out of the Instrument jack. • A high energy fuse F2 which is now in the BATTERY AND FUSE COMPARTMENT, and accessible without removing the Instrument case. • An OFF/TRANSIT position which has been added to the function switch to protect the meter movement during transit. (This, position shunts the meter movement and opens the internal connections to the COMMON and + jacks.) • A test lead set with molded elbow prods at one end for connection to the front panel input terminals and test probes at the other end. The test probes have a non-slip grip surface and a barrier to maintain the spacing between the user’s fingers and the Probe tip. Threaded shoulders at the Probe tip accept screw-on alligator clips (supplied) or an accessory AC or DC 5000 volt range extending probes.
