2 Safety
Safety is a priority! Observe and adhere to all safety information and
regulations; only use the HVA34 for appropriate applications and ensure that
operators possess the required operator qualifications and training.
2.1 General Safety
2.2 Work Safety
NOTICE
Operation Manual
Before carrying out any high voltage test with this instrument, read this
Operating Manual in its entirety.
DANGER
Electric Shock Hazard
Never assume that equipment is safe to handle without using the
necessary safety equipment and grounding procedures.
•All procedures must comply with local safety regulations
•Always treat exposed connectors and conductors as potential electric
shock hazards.
•DUT (Device Under Test) must be grounded, de-energized and
isolated from all power sources.
•All auxiliary electrical apparatus such as switchgear, surge arresters
etc. must be isolated from the test power source and the DUT.
•All cables and connectors must be inspected for damage before use.
Damaged equipment must not be used.
•Earth connections must be made first and removed last!
•DUT must be discharged and earthed before disconnecting the test
lead.
•Avoid testing alone. In the event of an emergency another person’s
presence may be essential.

User Manual
HV Diagnostics Page 8 Rev 9.0
DANGER
Authorized Personnel Only
The test area must be secured to keep non-qualified personnel off the
premises!
•Signs must warn all persons of the high voltage test area.
•Only qualified electrical technicians should have access to the test
area.
•Other persons must be accompanied by qualified electrical
technicians and must be informed of the risks involved.
WARNING
Radiation Hazard
Testing vacuum bottles, above their voltage rating, with DC can produce
dangerous X-rays.
NOTICE
Equipment Handling
DUT must have clean connections.
Test instruments must only be repaired or modified by authorized
HV Diagnostics’ personnel.
NOTICE
If required according to local safety regulations
Wear high voltage gloves when handling high voltage cables and
equipment.
