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 g to 4100 g. The 65 g through 410 g 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.

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 irregularites 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.
Connecting Power
NOTICE: The socket/outlet must be installed near the equipment 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.
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.

- 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.
- 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.
Calibration Masses
Before beginning calibration, make sure masses are available. If you begin
calibration and realize calibration masses are not available, exit the
procedure by pressing and holding Mode Off until balance returns to weigh
mode. The balance will retain previously stored calibration data. Calibration
should be performed as necessary to ensure accurate weighing. Masses required
to perform the procedures are listed in the following table.
CALIBRATION MASSES
Span Calibration
- With the balance turned ON, press and hold >O/T< until CAL is displayed.
- Release >O/T<, -C- momentarily displayed followed by the value of the calibration mass which is to be placed on the pan. Do not disturb the balance when -C- is displayed. Incorrect calibration may result.
- Place the indicated span calibration mass on the pan.
- Press >O/T<, -C- is momentarily displayed, then the weight of the mass on the pan is displayed.
- Remove the calibration mass from the pan. The balance is now calibrated and returns to the weighing mode.
Linearity Calibration
- With the balance OFF, press and hold >O/T< until MENU is displayed, then release it and UNITS is displayed. Press Mode Off, LIN is displayed.
- Press >O/T<, -C- is displayed followed by the value of the first mass which must be placed on the pan.
- Place the required mass on the pan and momentarily press >O/T<, -C- is displayed followed by the value of the next mass to be placed on the pan. Do not disturb the balance while -C- is displayed.
- Place the second required mass on the pan and momentarily press >O/T<, -C- is displayed. When the weight on the pan is displayed with the stability indicator, the balance is calibrated and returns to the weighing mode.
- Remove the calibration masses from the pan.
CARE AND MAINTENANCE
To keep the balance operating properly, keep the housing and platform clean. If necessary, a cloth dampened with a mild detergent may be used. Keep calibration masses in a safe dry place.
RS232 COMMAND DATA TABLE
NOTE: Print commands entered through the computer are temporary. When the balance is turned off, it will return to balance menu settings when turned on again.
TROUBLESHOOTING
Error Codes
When a problem occurs using the balance, the display will indicated an error
code. Review the listed codes and follow instructions to correct the problem.
- Err 2.0 Stability error. Check if balance is located near vibrating equipment or if air currents are affecting it.
- Err 3.0 Calibration error (wrong mass). Incorrect or no calibration mass used when performing calibration procedure. Error will flash momentarily, then balance will use previous calibration data. Recalibrate correctly.
- Err 4 Invalid data checksum in type or adjust data. Return balance for servicing.
- Err 6.0 Parts counting error – Average piece weight is less than 1d. Balance shows error then exits parts counting.
- Err 8.4 Over or under load. Sample being weighed exceeds the capacity of the balance. If error occurs when the sample is within the balance capacity, balance may be incorrectly calibrated. An underload such as the pan off of the balance could also display
- Err 8.4. Recalibrate the balance.
- Err 9 Internal data error. Return balance for servicing.
- Err 9.8 Invalid checksum in calibration or setup data. The balance may need recalibration, particularly linearity calibration. If the error persists after recalibration, thebalance must be serviced.
