Section 1 - Introduction
1. Introduction
Thank you for deciding to purchase a MB35 Halogen Moisture Analyzer from Ohaus. Behind your instrument stands
OHA S, 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.
Your Moisture Analyzer employs state of the art technology and meets the latest demands regard-
ing instrument safety. Improper operation can endanger personnel and can cause property dam-
age. 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 equip-
ment grounding conductor may be used. Intentional disconnection of the equipment grounding
conductor is prohibited.
1.1 Sa ety Precautions
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 chamber 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, discon-
nect the instrument from the power supply and wait until the dryer unit has cooled down
completely.

Section 1 - Introduction
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 flam-
mability of a sample, always work with a small sample (maximum. 1 gram). In such cases,
never leave the instrument unattended! 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 con-
dense 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 care-
fully; 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 OHA S dealer for an immediate replace-
ment.
APPLICATION DISCLAIMER:
 Moisture determination applications must be optimized and validated by the user according
to local regulations. Application specific data provided by Ohaus is provided for reference
purposes only. Ohaus waives all liability for applications based on this data.

2. Installation
This section contains unpacking and installation instructions for your new Moisture Analyzer .
2.1 Unpacking and Checking Equipment
Open the package and remove the instrument and the accessories. Check the completeness of the delivery.
The following accessories are part of the standard equipment of your new Moisture Analyzer.
 1 Box, Aluminum sample pans
 1 Pan support
 1 Specimen sample (circular, absorbent cellulose disk)
 1 Draft shield element
 1 Heat shield
 1 Power cable
 1 Set of operating instructions
 1 Warranty card
Remove packing material from the instrument. Check the instrument for transport damage. Immediately inform your
Ohaus dealer if you have complaints or parts are missing. Store all parts of the packaging. This packaging guaran-
tees the best possible protection for the transport of your instrument.
2.2 Selecting the Location
The Moisture Analyzer should always be used in an environment which is free from excessive air currents, corrosives,
vibration, and temperature or humidity extremes. These factors will affect displayed weight readings.
DO NOT install the Moisture Analyzer next to:
 Open windows or doors or vents causing drafts or rapid temperature changes.
 Near vibrating, rotating or reciprocating equipment.

2.4 Connecting to a Power Supply
Check to ensure the voltage identification label on the Moisture Analyzer matches your local line
voltage.
The halogen dryer unit is designed to operate at a specific line voltage (120 V ac or 240 V ac).
CAUTION:
Connection to line voltages that are above or below the rated voltage can cause improper opera-
tion or damage to the unit.
Connect power cord as shown. The MB35 is operational when power is applied.
The display remains off until the On/O button is pressed.
WARNING:
If the power cable supplied is not long enough, use only a proper 3-pin extension cable with
an equipment grounding connector.
Allow the Moisture Analyzer to warm up or at least 30 minutes to stabilize when turned on.
