Warning
High voltage testing should only be carried out by trained personnel.
Do not hold this instrument in your hand when testing uninsulated voltages
above 300VDC.
Fiberglass Operating sticks must be used.
--------------
This device is for indication only and should only be used by trained
personnel on the safe operations of the device.
Warning. the indicator will not indicate when conductors are in a high
field area, close proximity to one another, in a metal case enclosed
spaces or in armored metal screen cable.
The DC field can be compromised and the device will not indicate, it is
recommended from the manufacturer if adequate space, approach the
conductor from 360 degrees and on the high setting get within 5 mm.
Before touching conductors prove the conductor is zero volts using
existing convention testing equipment.

DC80 Unit Operations
Turn on the device, press the Power Button.
A single RED LED will illuminate
Press the green start self-test button. The unit is now operational.
The SELF TEST button can be applied at any time the
Indicator is functioning
By pressing the blue arrow up and arrow down button, the
single RED illuminated LED will switch between L.E.D 8
and L.E.D 1.
Note: LED 8 is the most sensitive and LED 1 is the least sensitive.
Press the green start self-test button. The unit is now
operational.
The SELF TEST button can be applied at any time the
Indicator is functioning.

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.

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.
