Always turn the power off and discharge all the capacitors before resetting the
switches or disconnecting the leads.
Always connect the Instrument in series with the ground side of the circuit under
measurement and never exceed the circuit to ground voltage (Table 1-1, item 7).

Set the function switch to +DC.
Plug the black test lead into the -COMMON jack and the red test lead into the
+50 µA/250V jack.
Be sure the power is off in the circuit being measured and all capacitors are
discharged.
Open the circuit in which the current is to be measured. Connect the red test
lead at the positive side and the black test lead at the negative side.
Turn the power on and read the current on the black DC scale. Use the 0-50
figures to read directly in µA.
Turn the power off, disconnect test leads and return the range switch to the
OFF/TRANSIT position.
Set the function switch to +DC.
Plug the black test lead into the -COMMON jack and the red test lead into the
+jack.
or 500 mA.
Turn the power off, discharge all capacitors, and open the circuit in which the
current is being measured. Connect the Instrument in series with the circuit.
Connect the red test lead to the positive side and the black test lead to the
negative side.
Turn on the power to the circuit under test.
Read the current in mA on the black DC scale marked 0-50. For the 0.5 mA
and 5 mA ranges, divide the reading by 100 or 10, respectively. Read the 50
mA range directly. Multiply the reading on the 500 mA range by 10.
Turn power off, disconnect test leads and return the range switch to the OFF/
TRANSIT position.
Plug the black test lead into the -5A jack and the red test lead into the +5A
jack.
Set the range switch to the 5A position (dual position with 5 mA).
Connect the Instrument in series with the circuit. Connect the red test lead to
the positive side and the black test lead to the negative side.
Turn on power in the circuit under test.
NOTE: The function switch has no effect on polarity for the 5A range.
Read current directly on the black DC scale. Use the 0-50 figures; divide by
10 to read amperes.
Turn power off and disconnect test leads. Return the range switch to the
OFF/TRANSIT position.
Set the range switch at the 25V (50 µA) position.
Measuring Direct Current: 0-0.5 through 0-500 mA
Set the range switch at one of the four range positions marked 0.5 mA, 5 mA
Measuring Direct Current: 0-5 A
With power OFF, open the circuit in which the current is being measured.
Measuring Direct Current: 0-50 µA

The Simpson Volt-Ohm-Milliammeter 260 Series 6XLM (hereafter referred to as
the 260 or the Instrument) is equipped with a mirrored dial to eliminate parallax.
The 260 is a high performance, battery-operated Volt-Ohm-Milliammeter capable
of making a wide variety of electrical measurements simply and accurately. Fea-
tures are overload protection, conventional and low-power ohms, and a wide range
coverage. The cases are made of high-impact (ABS) plastic, and are contempo-
rary styled. These features, in combination with extended range coverage (Table
1-1) make these Instruments general-purpose, portable, or laboratory Instruments.
They are well suited to servicing, production, inspection and engineering applica-
tions.
The 260 uses the Simpson taut-band movement, which is self-shielding. The taut-
band suspension provides a high degree of repeatability and is highly resistant to
shock or vibration.
Each Instrument is furnished with one pair of test leads four feet long. For polarity
identification, one lead is black and the other red. The test lead wire consists of a
large number of fine strands to ensure flexibility.
The insulation of the wire is high-grade rubber and is more than adequate for the
highest voltage the Instrument is intended to measure. The red and black test
leads have probe tips which are threaded near the base. The alligator clips may
be screwed on or off either test lead to provide a probe or a clip for the operator’s
convenience.
All Accessories and supplies required for the operation of the 260 are furnished
with the Instrument, and listed in Table 1-2. (Replacement parts are listed in Table
5-1.)
Table 1-1 lists the technical specifications for the Simpson 260-6XLM Volt-Ohm-
Milliammeter.
NOTE: Accuracy specifications apply to measurements made with the Instrument
in a horizontal position (meter facing upward). Reference Conditions: +25°C, ±5°C;
45% to 75% relative humidity.
