Getting to know your Moisture Analyzer - Section 1
1. Getting to know your Moisture Analyzer
This section provides you with essential information on your MB45 Moisture Analyzer. Please read through the
section carefully even if you have previous experience with OHAUS Moisture Analyzers and be sure to familiarize
yourself with the safety notes.
1.1 Introduction
Thank you for deciding to purchase a MB45 Halogen Moisture Analyzer from Ohaus. Behind your instrument
stands OHAUS, a leading manufacturer of precision Moisture Analyzers, Balances, Scales and Indicators. An
Aftermarket Department with trained instrument technicians is dedicated to provide you with the fastest service
possible in the event your instrument requires servicing. OHAUS also has a Customer Service Department to
answer any inquiries regarding applications and accessories.
To ensure you make full use of the possibilities offered by your Moisture Analyzer, please read the manual
completely before installation and operation.
1.2 Overview of the Moisture Analyzer
The Moisture Analyzer offers a high level of operating convenience and useful functions to make accurate
measurements.
The Moisture Analyzer has the following features:
 Up to twice as fast as IR Moisture Analyzers.
 Fully programmable with front panel controls.
 Extremely rugged and chemically resistant construction.
 Ergonomic operating controls and a large, easily readable display.
 Easy to follow menus for simplified operation.
 Built-in functions for manual, automatic timing, printing intervals, and custom units.
 Built-in selectable drying profiles.
 Able to set step heating levels to accommodate a variety of sample types.
 Built-in library stores up to 50 samples complete with setup parameters.
 Built-in RS232 communication interface.
 Any of five languages (English, French, Spanish, German, Italian) are selectable on the display.
 Display contains all test data during drying process.
 A variety of accessories includes disposable pan liners, calibration mass, temperature calibration kit,
interface communication cables, printer, and a security device.
1.3 What is a Moisture Analyzer?
The Ohaus Halogen Moisture Analyzer can be used to determine the moisture content of practically any sub-
stance. The instrument operates on the thermogravimetric principle: At the start of the measurement, the Mois-
ture Analyzer determines the weight of the sample; the sample is then quickly heated by the integral halogen
dryer unit and moisture vaporizes. During the drying operation, the instrument continuously determines the
weight of the sample and displays the result. On completion of drying, result is displayed as % moisture con-
tent, % solids, weight or % regain.

Section 1 - Getting to know your Moisture Analyzer
Of particular importance in practice is the rate of heating. In comparison with conventional infrared heating or
the drying oven method, for example, the halogen dryer of your instrument needs a shorter time to reach its
maximum heating power. It also allows the use of high temperatures; an additional factor in shortening the
drying time. Response times for the control of production are shorter resulting in increased productivity.
All parameters of a measurement (drying temperature, drying time, etc.) can be pre-selected. The Moisture
Analyzer offers many other possibilities. A few of these are listed here:
 The integrated database for drying procedures stores the settings for your samples.
 The drying characteristics can be matched to the type of sample.
 You can choose between various types of result displays at any time.
 Your settings and measurement results can be recorded and stored.
 Built-in battery backup stores valuable data during a power failure.
Even though the Moisture Analyzer contains many functions, operation remains simple. The three button
controls on the front panel: Test Menu, Display and Setup allows entry into a variety of displays which includes
a test library where previous samples are recorded along with the test parameters so that a similar sample can
be run without the need to enter all new data. There are additional displays which indicate the test ID number,
selected temperature, actual temperature, time, initial weight and moisture content in percent, solids in percent,
grams or custom unit, % regain and a graphical display which illustrates the time and percentage.
Your Moisture Analyzer conforms with all common standards and directives. It supports standard procedures,
work techniques and records as required by GLP (Good Laboratory Practices) and SOP (Standard Operating
Procedure). We recommend the use of the OHAUS AS-142 Printer. Your Moisture Analyzer has a CE declaration
of conformity and OHAUS is registered to ISO 9001 - Quality Management System.

Getting to know your Moisture Analyzer - Section 1
Your Moisture Analyzer employs state of the art technology and meets the latest de-
mands regarding instrument safety. Improper operation can endanger personnel and
can cause property damage. For safe and dependable operation, please comply with
the following instructions:
 The Moisture Analyzer is used for determination of the moisture in samples. Please
use the instrument exclusively for this purpose. Any other type of use can endanger
personnel and damage the instrument or other property.
 The Moisture Analyzer must not be operated in a hazardous environment and only
under ambient conditions specified in these instructions.
 The Moisture Analyzer may be operated only by trained personnel who are familiar
with the properties of the samples used and with the handling of the instrument.
 Your Moisture Analyzer is supplied with a 3-pin power cable with an equipment
grounding conductor. Only extension cables which meet the relevant standards and
also have an equipment grounding conductor may be used. Intentional disconnec-
tion of the equipment grounding conductor is prohibited.
1.4 Safety is first
The Halogen Moisture Analyzer works with heat!
 Ensure sufficient free space around the instrument to avoid heat accumulation and
overheating (approximately 1 m free space above the instrument).
 Never place flammable materials on, below or next to the instrument as the area
around the dryer unit warms up.
 Exercise caution when removing the sample. The sample itself, the sample cham-
ber and any sample containers may still be very hot.
 During operation, you should never open the dryer unit as the ring-shaped heating
element or its protective glass can reach 400°C! If you have to open the dryer unit on
occasion, disconnect the instrument from the power supply and wait until the dryer
unit has cooled down completely.

Section 1 - Getting to know your Moisture Analyzer
Certain samples require special care!
With certain types of samples, there is a possibility of danger to personnel or damage to
property through:
Fire or explosion:
 Flammable or explosive substances;
 Substances containing solvents;
 Substances which release flammable or explosive vapors when heated.
With such samples, work at a drying temperature that is low enough to prevent the
formation of flames or an explosion and wear protective goggles. Should there be
any uncertainty regarding the flammability of a sample, always work with a small
sample (maximum. 1 gram). In such cases, never leave the instrument unat-
tended! In cases of doubt, perform a careful risk analysis.
Poisoning, burning:
 Substances which contain toxic or caustic components. Such substances may be
dried only in a fume hood.
Corrosion:
 Substances which release corrosive vapors when heated (e.g. acids). In the case
of such substances, we advise you to work with small amounts of samples as the
vapor can condense on cooler housing parts and cause corrosion.
Please note that the user always takes responsibility and assumes liability for
damage caused by use of the types of samples mentioned above!
 Never make any modifications or constructional alterations to the instrument and
use only original spare parts and optional equipment from Ohaus Corporation.
 Your Moisture Analyzer is a rugged, precision instrument  but you should still treat it
carefully; it will then provide you with many years of trouble-free operation.
 Please comply with all notes and instructions in these operating instructions. Keep
the instructions in a safe place where they are immediately at hand if any points are
unclear. If you lose these instructions, please contact your OHAUS dealer for an
immediate replacement.

2.5 Connecting to a power supply
Check to ensure the voltage identification label on the Moisture Analyzer
matches your local line voltage. If this is not the case, do not connect the
Moisture Analyzer to the power supply, contact your responsible OHAUS
dealer.
The halogen dryer unit is designed to operate at a specific line voltage
(120 V ac or 240 V ac). The dryer unit is installed at the factory and is
matched to the particular line voltage of the country of destination.
Connection to a line voltage that is too high can lead to burning out the
halogen heater, whereas, a supply voltage that is too low will prolong the
drying process and the instrument may not operate properly.
2.4 Leveling the Moisture Analyzer
Exact horizontal positioning and stable installation are prerequisites for repeatable results. To compensate for
small irregularities or inclinations at the location, the instrument can be leveled.
Adjust the leveling feet at the rear of the Moisture Anlyzer until the air
bubble in the indicator is centered. The level indicator is located under
the cover towards the rear of the Moisture Analyzer.
NOTE: The instrument should be leveled each time its location is
changed.

Observing the test progress
There are five displays available when the Moisture Analyzer is running a test. The Display button on the front
panel when pressed repeatedly accesses each of the five displays during the run mode of the Analyzer and
cycles though each display in the order shown below.
The displays indicate the Test ID, Temperature/Time, Initial Weight, actual temperature, elapsed time duration of
the test, either moisture, solids, grams, percent regain or a graph representing the actual test progress.
Press the Display button repeatedly to view the progress of the sample test with different displays.
The test automatically stops at the end of 10:00 minutes. If you want to end the test sooner, press the START/

Making a simple measurement - Section 3
Carefully remove the sample pan handler from the drying area.
Warning: As the pan and sample may still be hot, you should let
these cool down before removing the pan from the pan handler!
To remove the sample pan from the pan handler, lift the pan slightly from
below and pull it sideways out of the pan handler (if you no longer need
the sample and pan, you can simply tilt the pan handler until the pan
slides out).
TARE
The last display from the test remains on the screen until you press the
Tare button.
Press the Tare button. This sets the Moisture Analyzer to zero. The
display returns to the first test display, ready to repeat the test.
If you want to get out of the test mode, simply press any other button on
the unit.
Continue to review the rest of this manual and become familiar with the
menus.
