This manual covers Installation, Operation and Troubleshooting for the Ohaus
ANALYTICAL Plus Series of Electronic balances, Models AP110, AP210, AP310,
AP250D, AP110E, AP210E, AP310E and AP250E. Suffixes after the basic model
number are: D = Dual Range and E= Type Approved with CE conformance and bear
official markings (Max, Min, Class, etc.) on a serial number plate located on the side
of the balance. To ensure proper operation of the balance, please read this manual
completely.
DESCRIPTIONDESCRIPTION
DESCRIPTION
DESCRIPTIONDESCRIPTION
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 aluminum base finished with a durable corrosion resistant epoxy powder
paint. The weighing 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
Analytical Plus balances contain four main display menus which enable you to
calibrate and configure the balance for specific operating requirements.
MENU MENU

EnvironmentEnvironment
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, alternators, etc.)
• on an unlevel work surface.
Install the balance in the location where it
will be used before proceeding.
Weigh Below HookWeigh Below Hook

Weigh Below HookWeigh Below Hook
A weigh below hook is provided inside the
bottom cover under the protective plate
shown in the illustration.
To access the weigh below hook, carefully 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.

RS232 INTERFACERS232 INTERFACE
RS232 INTERFACE
RS232 INTERFACERS232 INTERFACE
ANALYTICAL Plus balances are equipped with a bi-directional RS232 compatible
interface 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, as well as receive data such as displayed weight, weighing mode, stability
status, etc.
The following sections describe the hardware and software provided with the balance.
HardwareHardware
Hardware
HardwareHardware
On the rear of the balance, a 9-pin subminiature “D” connector is provided for
interfacing to other devices. The pinout
and pin connections are shown in the
adjacent illustration.
The balance will not output any data unless pin 5 (CTS) is held in an ON state (+3
to +15 V dc). Interfaces not utilizing the
CTS handshake may tie pin 5 to pin 6 to
defeat it.
Output FormatsOutput Formats

Output FormatsOutput Formats
Data output can be initiated in one of three
ways: 1) By pressing PRINT; 2) Using the
Auto Print feature; 3) Sending a print command (“P”) from a computer.
The output format is illustrated in the
RS232 command table which follows.

All communication is accomplished using
standard ASCII format. Only the characters shown in the following table are acknowledged by the balance. Any other
commands, control characters or spaces
are ignored. Commands sent to the balance must be terminated with a carriage
return (CR) or carriage return-line line
feed (CRLF). For example, a tare command should appear as shown in the
adjacent diagram. Data output by the balance is always terminated with a carriage
return - line feed (CRLF).

It remains in this range until the weight on the pan exceeds 52 g. When weight on the

Options under the Setup Options submenu. Under normal weighing conditions, the
movement of animal subjects on the balance platform causes unstable fluctuating
display readings and corresponding inaccuracies in the weighing result. The Animal
Weighing mode is a feature designed to minimize these fluctuations through a
combination of several digital signal processing techniques.
When used in this mode, the balance automatically detects the presence of a subject
placed on the platform and starts an animal weighing cycle. The balance samples the
weight data for a variable sampling interval and processes the data to filter out the
instabilities by the live animal.

methods are used to establish a reference for a 100% bar graph reading. Target
