Description
The Greenlee SVC-10 and SVC-20 Voltage and Continuity Testers are intended to measure
voltage, verify continuity, test diodes and perform phase sequence testing. Each model has a
large, easy-to-read LCD that has a maximum count of 999 and stow away leads.
In addition, the SVC-20 measures resistance and has an LCD backlight. The SVC-20 can also
be used to trip a ground fault circuit interrupt (GFCI) and has non-contact voltage detection
capability.

• Do not attempt to repair this unit. It contains no user-serviceable parts.
• Do not expose the unit to extremes in temperature or high humidity. See Specifications.
Failure to observe these precautions can result in injury and can damage the unit.
Unless measuring voltage, shut off and lock out power. Make sure that all capacitors
are discharged. Voltage must not be present.
Using this unit near equipment that generates electromagnetic interference can result
in unstable or inaccurate readings.
Important Safety Information
Do not change the measurement function while the test leads are connected to a
component or circuit.
Failure to observe this precaution can result in injury and can damage the unit.

Operation
1. See the Measurements Table and Typical Measurements.
2. Test the unit on a known functioning circuit or component.
•If the unit does not function as expected on a known functioning circuit, replace the
battery and/or fuse.
•If the unit still does not function as expected, send the unit to Greenlee for repair.
3. Take the reading from the circuit or component to be tested.
Note: The SVC-20 will trip a GFCI when the probes are connected between line and ground.

Operation (cont’d)
Phase Sequence Testing
In three-phase electrical systems, the phases are separated by 120 degrees of phase shift. The
first phase is the reference phase; the second phase lags the first by 120 degrees; the third
lags the second by 120 degrees.
Three-Phase Voltage Waves
Probe L1 Connection Probe L2 Connection Display
L1 / A / R L2 / B / S
L3 / C / T
L2 / B / S L3 / C / T
L1 / A / R
L3 / C / T L1 / A / R
L2 / B / S
The phases are identified with at least three different conventions:
•L1, L2 and L3
•A, B and C
•R, S and T
The phase sequence function of the SVC-10 and SVC-20 can determine the phase relationship
between two AC voltages. To use this function, connect L1 and L2 to two of the phases, and
touch the contact electrode. Compare the result on the display with the Phase Sequence Table.

•No intente reparar estas unidades, ya que contienen piezas que deben recibir
mantenimiento por parte de un profesional.
•No exponga estas unidades a ambientes de temperatura extrema o altos niveles de
humedad; consulte las “Especificaciones”.
De no observarse estas precauciones podrían sufrirse lesiones o daños a las unidades.
A menos que vaya a medir voltaje, apague y bloquee la energía. Asegúrese de que todos
los condensadores estén totalmente sin carga. No debe haber voltaje alguno.
Al utilizar estos verificadores cerca de equipo que genere interferencia electromagnética
quizáse obtenga una lectura inexacta e inestable.
Importante Información sobre Seguridad
No cambie la función de medición mientras los cables de prueba estén conectados a un
componente o circuito.
De no observarse estas precauciones podrían sufrirse lesiones o daños a los verificadores.
