IMPORTANT SAFETY WARNINGS
WARNING
• Read entire Safety Notes section regarding potential hazards
and proper instructions before using this manometer. In this
manual the word “
WARNING
” is used to indicate conditions
or actions that may pose physical hazards to the user. The
word “
CAUTION
” is used to indicate conditions or actions
that may damage this instrument.
• To avoid false readings, replace batteries if a low battery
indicator appears.
WARNING
•
WARNING
Do not exceed Maximum Over Pressure of
10 psi
.
• Do not use the manometer if it operates abnormally.
• Always test the manometer before use to ensure it is
operating properly.
• Always ensure that the connecting hoses you are using are
free from kinks, blockage or splits.
• Always double-check all connections before testing.
• While using the manometer, if you suspect gas is leaking, or
if you can smell gas, close off gas supply and ventilate the
occupied space. Identify and repair the source of the leak
before continuing with the test.
• Never connect the manometer to an unknown pressure
source if the source is twice the working pressure of the
instrument; the sensor may be damaged and it may
cause injury to the user.
• Never open the manometer or attempt to modify it in any
way. Otherwise, accident and injury may occur. And the
warranty is voided.
• These manometers do not measure water pressures; under
these conditions they will fail.
WARNING
• This manometer is designed for trained trade professionals
who are familiar with the hazards of their trade. Observe all
recommended safety procedures and use of personal
protective equipment.
