Min,Class,etc.)onaserialnumberplatelocatedonthesideofthebalance.Toensureproper
operation of the balance, please read this manual completely.
DESCRIPTION
The Ohaus ANALYTICAL Plus Series balances are high precision weighing instruments,
designed to be versatile, accurate, easy to operate and will provide years of service with
virtually no maintenance. The Analytical Plus series is constructed using a die-cast
aluminumbasefinishedwithadurablecorrosionresistantepoxypowderpaint.Theweighing
area is protected from air currents by a draft shield. It contains solid-state precision
electronics PC boards, and a seven and a half, 0.5 inch digit, Vacuum Fluorescent display.
Each balance operates through a series of menus which enhances operation. A built in
lockswitch prevents preset settings from being changed.
FEATURES
AnalyticalPlusbalancescontain fourmaindisplaymenuswhichenableyoutocalibrateand
configure the balance for specific operating requirements. MENU When
ON
TARE
switch is
pressed and released with MENU displayed, allows access to the calibration, user, setup
and print menus.
CALIBRATION Menu- Allows thebalance to becalibrated byusingeither Auto,Useror
Test calibration methods. The test function is used to verify the last calibration.
USER Menu - Allows the balance to be set for environmental conditions. Reset,
averaging level, stability range and auto-zero functions can be set.
SETUP Menu - Allows the balance to be customized for specific weighing functions.
PRINT Menu-Allows the selection of parametersunderwhich the balance willinterface
to a computer or a printer.
Eachofthesemenuscontainselectableparameterswhichcanbeenteredviathefrontpanel
switches. Storing of the parameters is accomplished by selecting at the completion of all
selections in a particular menu. For a detailed description of each feature, refer to the
individual menus in this manual.

INSTALLATION
UNPACKING
Your ANALYTICAL Plus balance was shipped with the following items:
•Pan assembly (including pan, shield, ring and assembly instructions)
•In-service cover
•AC power cord
•Spare fuse
•Instruction manual
•Warranty card
Remove the contents from the carton and carefully remove all packing material. It is
recommended to save the carton and packing material for storing and/or transporting the
balance. Verify that all of the components have been included and there has been no
damage during shipment.

INSTALLATION
Environment
The balance 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 balance:
•next to open windows or doors causing drafts or rapid temperature changes.
•near air conditioning or heat vents.
•near vibrating, rotating or reciprocating equipment.
•near magnetic fields or devices that may generate magnetic fields (i.e. motors, alterna-
tors, etc.)
•on an unlevel work surface.
Install the balance in the location where it will be used before proceeding.
Weigh Below Hook
Aweighbelowhookisprovidedinsidethe
bottom cover under the protective plate
shown in the illustration.
To access the weigh below hook, care-
fully turn the balance on it's side, loosen
the screw which secures the cover plate,
rotate the plate to clear the hole, then
secure the plate in that position. Return
the balance to an upright position. Mount
the balance on a stable, level elevated
platform and install a hook.

TARE COMMAND
RS232 INTERFACE
ANALYTICAL Plusbalances areequipped witha bi-directionalRS232compatibleinterface
for communication with printers and computers. When the balance is connected directly to
a printer, displayed data can be output at any time by simply pressing PRINT, or by using
the Auto Print feature.
Connecting the balance to a computer enables you to operate the balance from the
computer,aswellasreceivedatasuchasdisplayedweight,weighingmode,stabilitystatus,
etc.
The following sections describe the hardware and software provided with the balance.
Hardware
On the rear of the balance, a 9-pin subminia-
ture“D”connectorisprovidedforinterfacingto
otherdevices.Thepinoutandpinconnections
are shown in the adjacent illustration.
Thebalancewillnotoutputanydataunlesspin
5(CTS)isheldinanONstate(+3to+15Vdc).
Interfaces not utilizing the CTS handshake
may tie pin 5 to pin 6 to defeat it.
Output Formats
Data output can be initiated in one of three
ways:1)BypressingPRINT;2)UsingtheAuto
Print feature; 3) Sending a print command
(“P”) from a computer.
The output format is illustrated in the RS232
command table which follows.
RS232 Commands
Allcommunicationisaccomplishedusingstan-

to the balance must be terminated with a

feed (CRLF). For example, a tare command
should appear as shown in the adjacent dia-

terminated with a carriage return - line feed
(CRLF).

Connecting Power
1. Before connecting the power cord, check
that the line voltage switch located at the
rear of the balance is set correctly for your
location. If not, use a small screwdriver to
set the switch correctly.
2. Makesurethedoorstotheweighingcham-

2. Connect the power cord receptacle to the
plug on the rear of the balance.
3. Plug the power cord only into a convenient
grounded AC outlet. The balance signals
one long beep to indicate power has been
applied.
Spare Fuse
A spare fuse is provided in the fuse holder as
shown in the diagram. All models use a
T 160 mA/250 V fuse.
Self Test
When power is applied to the balance, it begins
a self test cycle. During this time, the display
cycles as shown.
NOTE: Sr shown in the display is the software
revision and may be different in your balance.
