WARNING
Read entire Safety Notes section regarding potential hazard
and proper instructions before using this meter. 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 the batteries if a low
battery indicator appears.
WARNING
• Do not exceed Maximum Over Pressure of ±10 PSI.
WARNING
• 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 connection 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 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 pressure; 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.
