1. Introduction
Thank you for choosing the U.S. Solid USS-HMA03 Moisture Analyzer.
The USS-HMA03 moisture analyzer is precise and reliable. It provides a
high level of operating convenience and response sensitivity to facilitate
determination of the moisture content of your samples. U.S. Solid’s
dedicated customer service staff are available to answer any inquiries
regarding applications and accessories.
To make full use of the functions and performance of the U.S. Solid
USS-HMA03 moisture analyzer, please read the manual completely and
follow the usage instructions before installation and operation.
1.1 About Halogen Moisture Analyzer
Moisture analyzers work according to the thermogravimetric principle.
Moisture is determined by the direct weight lost by the sample due to
heating from an intense halogen light.
The U.S. Solid USS-HMA03 Halogen Moisture Analyzer determines the
initial weight of the sample. The sample is quickly heated by the internal
halogen dryer unit causing the moisture to vaporize. During the drying
operation, the instrument continuously determines the weight of the
sample and displays the loss of moisture. Upon drying completion, the
moisture content or the dry solids content of the sample is displayed.

2. Safety Precautions
U.S. Solid Moisture Analyzer qualifies as state-of-the-art technology and
complies with all recognized safety rules. Improper use or handling,
however, can result in damage and/or injury. Follow the precautions
below to ensure safe and trouble-free operation of your moisture
analyzer.
2.1 Definition of Warning Symbols
Electrical shock
Inflammable/explo
sive substance
Hot surface
Toxic substance
Acid / Corrosion
General hazard
2.2 Warnings
•The Analyzer has a 3-pin power socket equipped with a
ground terminal. To prevent electric shock and to maintain
stability in operation of the product, be sure to ground the product.

4
•Avoid allowing the analyzer to get wet. It is not a water-resistant
structure. Any leakage of liquid into the analyzer may cause damage to
the analyzer or an electric shock to the user.
•Use a power source (voltage, frequency, outlet type)
adapted to the specification of the analyzer. If excessive
voltage is used, the analyzer may overheat and be damaged or cause a
fire.
•Do not measure samples that could cause a dangerous chemical
reaction or create an explosion or poisonous gas, when the sample is
dried.
•Keep flammables away from the analyzer. Parts of the analyzer
become very hot. Materials placed near it might catch fire.
•Do not touch the heater cover, the halogen lamp,
glass-housing, pan handle, sample pan or sample without
adequate protection, burns or scalding may result.
•Parts of the analyzer are very hot when a measurement finishes. For
operation, use the specified grips of the heater cover and pan handle.
Use the standard accessory tools.
•Toxic gases produced during the drying process of
substances containing toxic or corrosive ingredients may
cause irritation (eyes, skin, breathing), illness or death. Such substances
may be dried only in a fume cupboard.

5
•For substances that produce corrosive vapors when
heated (e.g. acids), work with small amounts of samples as
the vapor may condense on cooler housing parts and cause corrosion.
2.3 Cautions
•Operate the Analyzer on a stable, rigid and flat table.
•Handle the moisture analyzer carefully. It is a precision
device, subjecting it to impact may result in a malfunction.
•Ensure sufficient free space around the Analyzer as a safety zone.
Allow at least 1 meter of free space above the Analyzer. Do not place
anything on top of the heater cover.
•Use appropriate personal safety equipment, such as safety glasses,
gloves and protective clothing.
•If an abnormal situation occurs ( for example, a burning odor is
smelt), remove the power cable immediately.
•When the device will not be used for a long period of time, turn the
power off and disconnect the power cable.
•The Analyzer must be operated only by trained individuals who are
familiar with the properties of the samples being tested and with the
equipment operation.
•Do not disassemble, remodel or repair this product or accessories.
