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.
