How to Test
1. Rub the foam lid of the case with your hand
to build up static electricity (the more you
rub the higher the voltage charge will be)
2000 volts + can be generated.
2. Turn the indicator on and approach
the lid, the Indicator will light up as
you approach the lid of the case.
3. If the device if functioning correctly
the indicator will activate as you
approach.

7
Approach A known live conductor.
As the indicator moves into an electric field the indicators LEDS from 1 to 8 will
illuminate and an audio alarm will sound.
When all of the LEDS up to number 8 are indicated the audio alarm will be on
constant.
Insert the batteries correct polarity + to touchpad.

Is the indicator picking up static
electricity?
A static charge is on most surfaces.
If you are in an enclosed environment and you turn on the DC80 tester and it
activates.
Touch the black dissipative cap and the plate, if it has made contact with an
object it may be statically charged.
Turn off the indicator and switch the sensitivity setting to a lower setting until
the device is stable and you are not picking up a stray field.

9
Static Electricity 10 volts to
10,000+volts
The DC80 tester is designed to pick up an electric field emanating from an
active DC source as low as 50v dc.
Static electricity can be found on almost any surface.
Static electricity is an imbalance of electric charges within or on the surface
of a material.
The charge remains until the indicator is moved away from the area or by
means of an electric current or electrical discharge.
A static electric charge can be created whenever two surfaces contact and
separate, and at least one of the surfaces has a high resistance to electric
current (and is therefore an electrical insulator).
The effects of static electricity are familiar to most people because it can be
felt, heard and visually seen as a spark as the excess charge is neutralized when
brought close to an electrical conductor, or a region with an excess charge of
the opposite polarity (positive or negative).
The familiar phenomenon of a static shock –more specifically, an electrostatic
discharge –is caused by the neutralization of charge.
Static electricity is everywhere and is all around us. static electricity can be
generated by simply rubbing a piece of plastic on your shirt and removing it.
Dealing with Static charge has been the hardest phase to overcome to
manufacture.
How to combat static electricity

10
Once a DC power source is terminated in a plastic insulted cable, but not
earthed (grounded), a static charge remains present on the insulation, this will
slowly dissipate over time.
The DC80 indicator will read this static residue left behind and over time the
indicator sensitivity lights will stop indicating.
From trials conducted it can take up to several minutes for the static charge to
dissipate. The time is dependent on the thickness of the insulating material
and its composition.
Earthing the cable instantly removes the static charge in the cable.
Alternatively, you can Spray the target area with antistatic spray.
Approach the area to be tested, if the device alarms, repeat the process until
the DC80 does not pick up any signal.
If you test where live DC supply is present and the power is turned off, the
indicator will still show a decreasing DC field (static discharge).
If the insulated cable is sprayed with the antistatic spray it will negate the static
charge showing the operator that no potential is present.

DC80 Voltage Detector
Safety Information
DC80 was designed as a DC Proximity device to eliminate the dangers of touch
testing and earthing. It should be used by trained and qualified personnel only.
When testing DC circuits always use caution and strictly adhere to proper
safety practices.
Above 500VDC proper high voltage procedures for testing should apply.
Wearing personal protective equipment is a necessary safety precaution.
Read the User Manual carefully before using the Indicator.
The DC80 is a Proximity device but if it should ever make contact with a live DC
conductor no harm to the Indicator will occur but the Indicator cap will need to
be touched to dissipate the Static charge.
Prior to using the DC80 in the field, make sure to test and verify that sensitivity
settings are suitable for testing in that location.
Always check that the DC80 is working before using it in on site.
The risk of electrocution is paramount in and around high voltage.

Overview
DC80 is a non-contact DC voltage detector that alerts users when they
approach an electrified source. Its advanced notification system is designed to
warn the user of the presence of voltage and current within a proximate area.
DC internal sensors were designed to detect both electrical (V/m) and
magnetic (T) fields. Radiated electric and magnetic fields increase with higher
distribution voltages and decrease with distance and/or shielding. Once an
energized source is detected, the user is notified first by LED lighting of the
approximate distance and then is followed by indicating piezo buzzer. These
warnings are shown to the user by the line of LED lights.
Typical Uses
•Identify live conductors.
•Detect residual or induced voltages.
•Identify energized lines after power outages.
•Find energized lines underground.
•Detect energized threats after natural disasters.

Warnings
Industrial DC80 only detects DC Voltage.
Every energized DC conductor is surrounded by an electric field.
As you move closer to the conductor, the electric field will become stronger.
Lower voltages have a weaker field strength and will have a shorter warning distance.
Electric fields that have a stronger field strength, will have a greater warning distance.
Underground PRIMARY cables are both insulated and shielded. The shield is a
conductor, it is grounded, and will nullify the electric field.
Moulded cable terminators such as elbows - like the cables they are installed on - are
both insulated and shielded and will nullify the electric field.
Live conductors lying on the ground should be tested where they leave the earth
situation for test confirmation.
Electric fields will couple to the ground thus drastically reducing warning distances.
Treat all conductors as “live” unless or until there is a visible break from a live source
and a ground is in place.
Always use proper high voltage procedures, including personal protective equipment,
when working near or around high voltage equipment or conductors.
Before using DC80 in hand, learn the proper holding method. Not using the proper
positioning will prevent voltage from being detected.
Warning distances will be greatly reduced in high humidity and rainy environments.
Never submerge in water. If fully submerged, moisture could enter the enclosure and
damage detection sensors leading to reduced warning distances or failure to detect a
“live” voltage.
