HVAC Guide® System Analyzer
Field Manual
Model HG3
Do it right the first time!
The HVAC Guide® System Analyzer will reduce call-backs by giving you
a wide variety of tests to diagnose HVACR systems and lower your customer's
energy bills. It walks you step-by-step through each test procedure to make
your job easier, faster and better.
The New HG3 model has wireless capabilities. Set up the Fieldpiece Ac-
cessory Heads at multiple locations on the system with the wireless trans-
mitters (products ET2W or EH4W) and have all of the measurements and
calculations in the palm of your hand!
Test procedures are included for Superheat, Subcooling, Combustion
Analysis, Target Evap Exit Temperature (temperature drop across the evapo-
rator coil), CFM (air balancing), CheckMe!® Evaluation, and Charging Jacket
are built into the HVAC Guide to streamline each test. You select a test on the
dial, enter data on the INPUT FORM and view the results on the OUTPUT
FORM. Tests can be saved, downloaded to a PC and printed for customer
tracking or to hand back to customers.
The HVAC Guide® System Analyzer also has a data logging switch posi-
tion to record up to 13 measurements at one time. With the Display switch
position view one parameter by connecting any Fieldpiece Accessory Head
directly or wirelessly.
Do it right the first time, do it faster, easier, more completely, and avoid
call-backs in the process.
