PRINCIPLE OF HOW IT WORK-DISPLAYS-
RESULTS
The Fused Circuitry:
In series with each circuit is a HBC
or HRC fuse. These fuse protects the user and the circuit
against over-current.
The Neon Voltage Scale Indication and Display:
The
Voltmeters results are shown on a Neon Scales on both
sides. These voltmeters use a bar-graph style scale, with
the lower value on the left side, going clockwise to the
right. There are neon lights for
110V, 220V, 280V and 415V
As the voltage increase,
the neons lights up, as
shown on the right, neon
110V and neon 220V lit
to show that voltage on
the tips is at least equal
to 220V.
The Voltage Detector with LED:
The led Voltage
Detector lit up as soon as there is enough voltage across
the tips between the poles. This indicates that voltage
between the tips has reached a dangerous level and
therefore could be lethal. Once the Led lit, be extra careful.
The Voltage Detector with Buzzer:
The Acoustic Voltage
Detector sounds as soon as there is enough voltage
across the tips between the poles. This indicates that
voltage between the tips has reached a dangerous level
and therefore could be lethal. Once the Acoustic Voltage
Detector sounds, be extra careful.

SOME APPLICATIONS
l
Measure and confirm Overhead Voltage between Lines,
or Line to Earth/Ground and/or Lines to Neutral.
l
Measurements can be done in all Safety due to the
clearance from the probes contacts.
l
This is done when, for example, using a lift bucket from
a truck, then the technician can stand in the bucket,
and still can reach all the phases and check voltage
between each phases and between each conductors
without being at risk.
l
Check Voltage Presence between two conductors or
between Phase and Earth.
l
Measure and Detect Voltage between Bus bars and
between Bus bar and Earth.
l
Use where you are not comfortable with your normal
test leads.
l
Tips can be changed for different types.
l
Available tips: Fork type, Piercing trough Insulation,
Cone, Flat tip, Other tips on Demand.
