Warning to avoid shock or personal injury
• Follow all applicable equipment safety procedures.
• Inspect the calibrator before use. Do not use the calibrator if
it appears damaged.
• Close battery door and secure with lock screw before using
the calibrator.
• Check all test leads for continuity, damaged insulation or
exposed metal. Replace any damaged leads.
• Use the proper terminals, mode and range for any measur-
ing and sourcing application.
• Connect the common lead before connecting the live test
leads.
• To prevent damage to the unit under test, be sure that the
calibrator is in the correct mode before connecting leads.
• Never apply more than 33 volts between input terminals or
between any terminal and ground.
• When using probes keep fingers away from probe contacts.
• Do not allow water or other liquids inside the calibrator case.
• Do not operate the calibrator near explosive gas or vapor
unless the calibrator is marked as approved for hazardous
area service.
• Never open the ATE-2. There are no field serviceable
components. This will void the warranty.
• When measuring pressure, be sure that the process pres-
sure line is shut off and depressurized before connecting or
disconnecting a pressure module.
• Always use proper tools to avoid damage to pressure
measurement modules. Use a wrench to hold the module
manifold, and a second tool to tighten the mating fitting. See
drawing figure in section 12.
• Replace batteries only with approved AA alkaline batteries
(Quantity 4). Never mix new and used batteries in the cali-
brator.
Warnings for Intrinsically Safe approved versions only
(Refer to Supplement I.S. Manual I&M002-10212)
• When marked as approved the ATE-2 calibrator is agency
approved for use in areas when potentially flammable or
explosive gas or vapor may occur. These areas are referred
to as hazardous (classified) locations in the United States,
as hazardous locations in Canada, as potentially explosive
atmospheres in Europe and as explosive gas atmospheres
in other parts of the world. The HHC’s voltage and current
input jacks have entity parameters and as such can be uti-
lized in a hazardous location to connect to other apparatus
as long as said apparatus meets the requirements of the
entity parameters.
• When marked with the following Symbols the calibrator is
approved by Factory Mutual (FM) for use in Class 1 Division
1, Groups A,B, C,D hazardous areas, by ATEX for use in Ex
ia ll C T4 Ga -20C<Ta<+50C and by CSA for use in Class 1,
Division 1, Groups A, B, C, D
