This Operator’s Manual contains cautions and warnings alerting the user to haz-
ardous operating and servicing conditions. This information is flagged by CAU-
TION or WARNING symbols throughout this publication, where applicable, and is
defined on the inside front cover under NOTES AND SAFETY INFORMATION.
Adhere to these instructions in order to ensure the safety of operating and servic-
ing personnel and to retain the operating conditions of the Instrument.
This section contains information and instructions for the installation and shipping
of the Instrument. Included are unpacking and inspection procedures, shipping,
power source requirements, operating position and care.
Examine the shipping carton for any sign of damage. Inspect the Instrument and
packing material for obvious damage from mechanical shock, water leakage, or
other causes. Check the electrical performance as soon as possible. If there is
any indication of damage, file a complaint with the carrier immediately. Also check
that all accessories are included (Table 1-2). Save the shipping carton and pack-
ing materials for future storing or shipping of the Instrument.
On unpacking the Instrument from the box, a 1.5V and a 9V battery will be found
packed in separate envelopes. Two alligator clips for the test leads are packed in
a polyethylene bag. A pair of test leads, one black and one red, are also included.
Pack the Instrument carefully and ship it, prepaid, to the proper destination. In-
sure the Instrument.
Two batteries are in the ohmmeter circuits, a NEDA 13F, D size battery that fur-
nishes 1.5V all ranges up to R X 1k and a NEDA 1604 battery which furnishes 9V
for the R X 10k range.
The Instrument may be set horizontally or on its back and can be operated in
either position. The Instrument can also be set at an included angle by position-
ing a stand under the unit.

Prior to making voltage measurements, review the SAFETY PRECAUTIONS listed
in paragraph 4.2.
NOTE: The Simpson 260-6XLM responds to the full-wave average value of an
AC waveform. They are calibrated in terms of the RMS value of a pure sine wave.
If the waveform is nonsinusoidal, the reading might be either higher or lower than
the true RMS value, and could result in a substantial error. Also, accuracy is
lessened at higher input frequencies (Figure 4-1).

Plug the black test lead into the -COMMON jack and the red test lead into the
1000V jack. Connect the black test lead to the negative side of the circuit
being measured and the red test lead to the positive side.
Turn on power in the circuit being measured.
Read the voltage on the black scale marked DC, using the 0-10 figures. Mul-
tiply the reading by 100.
Turn the power off, disconnect test leads and return the range switch to the
OFF/TRANSIT position.
AC Voltage Measurement
Measuring AC Voltage
Set the function switch to AC.
Set the range switch to one of the six voltage range positions marked 2.5V,
10V, 25V, 100V, 250V or 500V. When in doubt about the approximate voltage
in the circuit being measured, always use a sufficiently high voltage range as
a protection to the Instrument. If the voltage is within a lower range, the
switch then may be set to a lower range to obtain a more accurate reading.
Plug the black test lead into the -COMMON jack and the red test lead into the
+jack.
Be sure the power is off in the circuit being measured and all the capacitors
