Simpson 260® Series SR

Analog - VOM

Educational Systems Volt-Ohm-Milliammeter

Simpson Catalog Number Unknown

The front of the Simpson 260-SR is the same as a 260-6P.

I do not know what the story is on this model, can anyone tell me?

 The Simpson 260-SR has the Taut Band Suspension dial, but does not have the green

"Amp Clamp" scales marked on the dial.

Controls include: Ohms zero adjustment, AC - DC Voltage selector switch, and a 12 position

Function / Range selector switch. Eight recessed probe jacks. The overload button is to the left of

the Simpson logo. The off or "transit" position is at the 500 MA location.

The clear rear case has raised bumps at the four corners. This is not a clear Series 6 case.

More inside views linked below.

This model uses the NEDA 13 F "D" cell and NEDA 1604A (9 Volt) batteries combination.

The separate battery / fuse cover is not used on the clear back.

Case Size: 5¼ " x 7 " x 3⅛ "  -  Weight: 3 Pounds

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