Failure to properly close the battery compartment and/or the use of weak
batteries may result in intermittent operation. Do not use the 275HVD
if intermittent operation occurs (see Testing the 275HVD Before
Operating § 1.1).
1.2 PRECAUTIONS FOR USE
The Model 275HVD Non-Contact High Voltage Detector has been designed
with safety in mind. However, no design can completely protect 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 is not taken or safety practices are not adhered to, electrical circuits
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.
