Simpson 260 Series 7PRT

Analog - VOM


Simpson Catalog Number Unknown

The front on the Simpson 260 Series 7PRT changes from the Series 6, by the addition of a "off / transit"

position on the AC/DC switch. The output jack is also marked as 350 VDC Max.

New for the Simpson 260-7PRT is the size of the meter cover.

While the glass is the same size as always the cover is now 5 " x 3 " instead of 5 " x 4 ".

The 260 Series 7PRT has the three Amp-Clamp scales.

Controls include: Ohms zero adjustment, Off - AC - DC Voltage selector switch,

and a 12 position Function / Range selector switch.

The eight recessed probe jacks are now the "Reverse-Banana" type for safety.

The white overload reset button is just to the left of the Simpson logo.

Starting with the 260 Series 7 and the 270 Series 5, the 1000 Volts to Ground rating is engraved

in or printed on to the face, just below the model number.

The rear case has instructions for removing the back for battery / fuse access.

More inside views linked below.

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

The 260-7PRT has the separate battery / fuse cover to allow you to change the batteries and fuses

after removing the back cover from the roll top case.
