HOW TO USE :
High Voltage Detection
(in stretched state) Low Voltage Detection
Subject
Naked/Insulated wires
3.3kV 6.6kV 24kV AC
Naked live part
80 ~ 600 VAC
Method
Put the front metal in
contact with the subject
line to detect voltage,
holding the grip portion.
IMPORTANT !
Don’t touch any portion
other than grip !
Please keep in your
mind to wear high
insulating gloves when
you measure
high voltage between
600V ~ 24KV AC
Put the front metal in
contact with the
subject line, holding
the nameplate portion.
HANDLING AND MAINTENANCE :
Before use for Voltage detection :
1. Check to see that nothing is wrong with the equipment in
appearance and construction.
2. Switch on test switch to check for working of the internal circuit
for cautions sake try with a known line for operation.
3. When inspecting a high tension line, hold the grip portion during
detecting operation.
Do not touch any portion other than the grip because danger is
involved.
4. When using the equipment in constructed state for inspecting a
high voltage line wear insulating rubber gloves.
5. For voltage detection in a low tension line hold the nameplate
portion.
6. If it is necessary at all to carry out voltage detection during
rainfall, pay constant attention to the wet condition of the
equipment.
Handling and Safekeeping :
7. Do not subject the equipment to any hard shock by dropping or
placing under something.
Do not wipe it with a chemical or the like.
8. Do not leave it on a road site in summer or place it in a hot
location in a car or the like.
9. Be sure to keep it clean at all times, and choose a dry location
kept away from direct sunlight for safe keeping.
