Simpson 260 Series 5M

Analog - VOM

Volt-Ohm-Milliammeter

Simpson Catalog Number

There is nothing new on the outside of the Simpson 260-5 series.

All improvements over the previous model are inside. This model takes the banana jack type test leads.

 The Simpson 260-5M has Taut Band Suspension and a mirrored dial to eliminate parallax errors.

Controls include: Ohms zero adjustment, AC - DC - Select, a 12 position Function / Range

selector switch, and eight recessed probe jacks. 

 

The back of the case has an "adapter lock" for use with "Add-A-Tester" accessories.

The printed circuit boards can now withstand higher voltages than previous models.

The batteries can be installed without taking the whole unit apart. The pigtail type fuse has been

modified by a former owner with a fuse holder for easier replacement of the 1 amp 250 Volt type 3AG.

More inside views linked below.

The batteries used in this model are a single "D" cell, plus four "AA" batteries, there are two "AA"

below the "D" and one "AA" on each side.  The batteries can be installed without 

doing anything but removing the back of the case.

Case Size: 5 " x 7 " x 3"  -  Weight: 3 Pounds

The Adjust-A-View handle can also support the meter in a sloping position for viewing.
