INTRODUCTION
This manual covers installation, operation and troubleshooting for the OHAUS® AdventurerTM Balances. To ensure proper operation of your balance, please read this manual completely.
DESCRIPTION
The Ohaus AdventurerTM balances are precision weighing instruments, designed to provide years of service with virtually no maintenance. Models are available with capacities from 65 to 4100g. The 65g through 310g balances include a draft shield. Weigh below operation is made possible with a built-in weigh below hook.
The AdventurerTM balances are constructed with a durable housing, leveling feet, built-in leveling bubble, and a large custom LCD. Control buttons are clearly marked as to their function, with large Tare buttons located on either side of the front panel.
All AdventurerTM balances are initially factory set to measure in grams and can be set to measure in *kilograms, milligrams, carats, Newtons, pounds, ounces, troy ounces, grains, pennyweight, mommes, mesghals, Hong Kong Taels, Singapore Taels, Taiwan Taels, Ticals, and Parts Counting. Simple three button operation allows for the selection of measuring units, calibration and printing parameters. A standard RS232 interface permits communication to an external printer or computer.
*See specifications for measuring units which are available.
Power is supplied through an AC adapter. Accessories include: an in-use cover, security device, calibration masses, printer, and scoops. See accessory section.
Behind your instrument stands OHAUS Corporation, a leading manufacturer of precision weighing equipment. 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 Corporation also has a Customer Service Department to answer any inquiries regarding applications and accessories.

•UNITS Menu - Allows up to 16 measuring units to be selected plus parts counting.
•LIN Calibration Menu - Allows the balance to be calibrated by using linearity calibration methods. Two masses are required.
•SYS Menu - Enables tone signal with each keystroke.
•PRINT Menu - Allows communication parameters to be set which include Baud rate, Parity, Data and Stop bits. A Reset function permits returning the communication parameters to factory settings.
•MENU END - When selected, balance returns to weigh mode.
UNPACKING
All AdventurerTM balances are supplied with a weighing platform, AC power adapter, built-in weigh below hook, instruction manual and warranty card. Draft shields are supplied with 65g through 310g balances.
Carefully unpack all items.
•Check the instrument for transport damage. Immediately inform your Ohaus dealer if you have complaints or if parts are missing.
•Store all parts of the packaging. This packaging guarantees the best possible protection for the transport of your instrument.
INSTALLATION Selecting the Location
The balance should be used indoors only and in an environment which is free from excessive air currents, corrosives, vibration, and temperature or humidity extremes (Max. 85%). Maximum altitude not to exceed 4000 m above sea level. These factors will affect displayed weight readings.
DO NOT install the balance:
•Next to open windows or doors causing drafts or rapid temperature changes.
•Near air conditioning or heater vents.
•Near vibrating, rotating or reciprocating equipment.
•Near magnetic fields or equipment that generates magnetic fields.
•On an unlevel or unstable work surface.
NOTE: Manufacturer cannot guarantee the safety of the product if it is not used according to the instructions.
Setting Up and Leveling the Balance
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.
For exact horizontal positioning, the balance is equipped with a level indicator and two leveling feet located at the rear of the balance.
Position the balance in the intended operating location. Adjust the leveling feet at the rear of the balance until the air bubble in the indicator is centered.
NOTE: The instrument should be leveled each time its location is changed.

NOTICE:
The socket/outlet must be installed near the equip ment and shall be easily accessible. For use with an certified (CSA or equivalent) power supply, which
must have a limited and SELV circuit output.
Connect the AC Adapter cord to the connector located at the rear of the balance and to a suitable power source.
Pan Installation
Place the pan support and pan on the balance. The balance is now ready for operation. Balances with a draft shield do not have a pan support.
Weigh Below Hook
For below balance weighing applications (eg. density determination), a weigh below hook is installed at the bottom of the balance and is part of the balance. To use, remove the protective plug cover located at the bottom of the balance. The balance should then be supported on an elevated level surface which allows access to the weigh below hook. The balance should be releveled. Measurements are made by the use of a fine wire attached to the internal weigh below hook.
CAUTION:
Do not attempt to remove the weigh below hook from the balance as the balance may be damaged.
Security Bracket
A security bracket which is cast in the lower housing is provided at the rear of the balance under the leveling bubble. This bracket allows the balance to be secured by an optional cable and lock accessory.

5.To read the weight of the parts, press Mode Off to change to any of the activated weighing units. You can return to parts counting at any time by repeatedly pressing Mode Off until the parts counting indicator is displayed. Sample weight is retained as long as the balance remains plugged in or you change it by the procedure above.
6.To exit to weighing mode, press Mode Off until desired unit is displayed. Press >O/T< to tare the balance.
CALIBRATION
AdventurerTM balances are calibrated before shipment, however, calibration can be affected by changes in location, temperature, or rough handling. AdventurerTM balances can be calibrated in two ways: Span calibration or Linearity calibration. Span calibration resets the balance's weighing range using two weight values: zero and a weight value at or near the balance's capacity. Linearity calibration minimizes deviation between actual and displayed weights within the balance's weighing range. Three weight values are used: zero, a weight value within the balance's weighing range and a weight value at or near the balance's specified capacity.
