SV225
Stray Voltage Eliminator
IVCAT
600
V
Introduction
The SV225 Stray Voltage Eliminator (hereafter referred to as
“the Adapter”) is a digital multimeter accessory that allows
measurements in circuits which may be subject to stray
voltages encountered from adjacent-energized wiring.
The Adapter provides an approximate 3,000 eload to the
measured circuit, desensitizing the meter to low energy,
spurious sources of interference. The Adapter is only used for
voltage measurements. When used with a compatible digital
multimeter, it can be determined whether the circuits under test
are energized or not.
Safety Information
XW Read First: Safety Information
To avoid possible electric shock or personal
injury:
•Read the operating instructions before use
and follow all safety instructions.
•Use caution when working with voltages
above 60 V dc or 30 V ac. Such voltages pose
a shock hazard.
•Before testing the desired circuit, ensure that
the multimeter and Adapter are functioning
properly by testing a known live circuit. A de-
energized circuit will be indicated on the
multimeter display as a reading near zero
volts.
•When using the Adapter to eliminate stray or
ghost voltage, the Adapter has a low input
impedance, nominally 3,000 Ω. This low
impedance places a moderate load on the
circuit under test. Do not use the Adapter to
measure live voltages in circuits that could be
damaged by a 3 kΩload.

•Do not apply more than the rated voltage, as
marked on the multimeter or in the Adapter
specifications (whichever is lower) between
the terminals, or between any terminal and
earth ground.
•Before each use, inspect test leads for
damage and check for continuity. Do not use
leads that are damaged or show high
resistance. Look for cracks or missing plastic
on the lead housing or cable insulation.
•Adhere to local and national safety codes.
•Individual protective equipment must be used
to prevent shock and injury.
•If the equipment is used in a manner not
specified by the manufacturer, the protection
provided by the equipment may be impaired.
•The Adapter is specified for CAT III
1000V/CAT IV 600V per EN61010.
•CAT III equipment is designed to protect
against transients in equipment in fixed-
equipment installations, such as distribution
panels, feeders and short branch circuits, and
lighting systems in large buildings.
•CAT IV equipment is designed to protect
against transients from the primary supply
level, such as an electricity meter or an
overhead or underground utility service.

Instrument Compatibility
The Adapter is for use with any high-impedance digital
multimeter (≥1 MΩ) which accepts 4 mm safety-shrouded
banana plugs and with any test leads using the same safety-
shrouded banana plugs. The Adapter is compatible with the
following Fluke digital multimeters and testers:
•Fluke 27
•70 Series
•80 Series
•Fluke-110 Series
•170 Series
•180 Series

Operation
To use the Adapter, do the following:
1. Plug the Adapter into the digital multimeter’s V/Ωand
COMMON input jacks.
2. Plug the test leads into the Adapter input jacks observing
the proper polarity (red lead to red jack, black lead to black
jack). Make sure the leads and Adapter are fully
connected to the instrument.
3. Turn the multimeter’s function switch to the Volts AC
measurement function.
XW Warning
To avoid possible electric shock or personal
injury, before testing the desired circuit, ensure
that the multimeter and Adapter are functioning
properly by testing a known live circuit. A de-
energized circuit will be indicated on the
multimeter display as a reading near zero volts.
4. After determining the circuit under test is de-energized,
retest the known live circuit again to insure the multimeter
and Adapter are still working properly.
Note
Most digital multimeters never display a zero-volt
reading for a de-energized circuit. A small residual
reading may always be present.
The example in Figure 1 shows a reading of 13.2
millivolts AC which is very close to a zero-volt reading.
1 millivolt is equal to .001 volts or 1/1000th of a volt.

Cleaning
WCaution
To avoid damaging the Adapter, do not use
abrasives or solvents for cleaning.
Periodically wipe the Adapter with a damp cloth and mild
detergent.
