Warning
The Model 275HVD Non-Contact High Voltage Detector has been
designed with safety in mind. However, no design can completely pro-
tect against incorrect use. The 275HVD should be used by trained and
qualified personnel only. The 275HVD can only be used with an insulated
rod or “Hot Stick” rated at the appropriate working voltage. The 275HVD
Non-Contact High Voltage Detector is never to be put into direct contact
with a live conductor.
If caution or poor safety practices are not adhered to, electrical cir-
cuits can be dangerous and lethal.
This instrument should only be used by authorized and properly
trained personnel who fully understand the High Voltage testing
procedures.
Personnel working with high voltages should be trained regularly.
• Read the user manual carefully and completely before using the
tester. Fully understand the instructions before using this product.
• Follow the instructions for every test.
• Take all the necessary safety precautions. Do not exceed the limits
of this instrument.
• The 275HVD Non-Contact High Voltage Detector must never be in
physical contact with any conductor. This is a proximity detector, not
a detector which works by contact.
• Tests must only be carried out with the 275HVD attached to an
approved insulated fiberglass rod or Hot Stick.
• Always use an authorized fiberglass (or equivalent) rod or Hot Stick
appropriately rated for the voltage with which you are working.
• Always check that the 275HVD Non-Contact High Voltage Detector
is working before and after the test.
• Verify the Range Switch setting before measuring. Make sure it is on
the correct setting for your application.
• Do not touch any exposed wiring, connections, or other “live” parts of
an electrical circuit.
