all assistance, including help with the Instrument under warranty, contact the
nearest Authorized Service Center for instructions. If necessary, contact the fac-
tory directly, give full details of any installation difficulty and include the Instru-
ment model number, series number, and date of purchase. Service data or ship-
ping instructions will be mailed promptly. If an estimate of charges for non-war-
ranty or other service work is required, a maximum charge estimate will be quoted.
This charge will not be exceeded without prior approval.
Pack the Instrument carefully and ship it prepaid and insured.
There are two batteries in the ohmmeter circuits, a NEDA 13F D size cell that
furnishes 1.5 volts for the R X 1 and R X 100 ranges and a NEDA 1604A battery
that furnishes 9 volts for the R X 10,000 range. The 1.5 volt D cell is held in place
with two spring clips which also serve as battery contacts. The 9-volt battery is
held in place with a spring clip but contact is made with a separate connector that
is polarized. (Always observe correct polarity when replacing the 1.5-volt D cell.)
A handle is attached to the side of the Instrument case. The handle may be used
to support the Instrument in a convenient, sloping position for easy viewing. The
VOM case can also be placed either in a vertical or horizontal position. The
horizontal position is preferable for greater accuracy since the Instrument is cali-
brated in this position.
All operating and adjustment controls, jacks, and indicators for the Simpson 260-
8P are illustrated in this section along with a list (Table 3-1) describing their
function. Become familiar with each item before operating the Instrument.
The front panel controls, jacks, and indicators as described in Table 3-1, are
depicted in Figure 3-1.

The 260-8P Volt-Ohm-Milliammeter is a large, easy-to-read
4-1/4” indicating Instrument. Below the Instrument are four
controls and eight circuit jacks. Switch positions and circuit
jacks are marked in white characters for easy reading.
12 positions: May be rotated 360° in either direction to
select any of the five AC and DC voltages, four DC cur-
rents and three resistance ranges.
