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.
