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.
