Non-contact voltage tester
Please read this manual thoroughly before use and keep it for later
reference.
WARNINGS
With this device, life-threatening voltages are tested, so special
care is required!
Always first test the voltage tester on a known circuit to make
sure it works!
When checking uninsulated contacts, wear safety shoes to prevent
electric shock.
When checking uninsulated contacts, hold the tester and make sure
your fingers are behind the anti-slip guard.
Do not use the device if:
- The screen is not lit;
- Damage is evident;
- The tip is not intact.
Do not put the device in more than 1000V
This equipment can only be used indoors and should be protected from
water, high air humidity and heat.
ATTENTION
: Even without indication, the voltage could still be present.
The voltage detector indicates the effective voltage when a supply
voltage generates enough intensive electrostatic field. If the field is very
weak, the voltage detector can
’
t detect the existence of voltage.
We do not accept any liability for property damage or personal injury
caused by incorrect operation or failure to follow safety instructions. In
this case, any warranty claim will lapse.
