1.4 Safety
Every effort has been made to make the Pavement Quality Indicator convenient
to use and inherently safe. The PQI uses no nuclear elements, and is instead
based on a safe, low-voltage direct current electrical measurement techniques.
Like any instrument, however, the user should exercise care and common sense
in its use to prevent mishaps.
Take careful note of the following:
Warning- Do not use the unit on or near exposed electrical wiring. A shock
hazard potential exists if contact is made with the exposed wiring.
Warning- Use care in handling the unit. Personal injury can occur through
improper handling. Take proper precautions to prevent accidental dropping of
the unit.
Caution- Turn the unit off when not in use and during transport.
Caution
