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 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 When

pressed and released with MENU displayed, allows access to the calibration, user, setup and print menus.

TARE

switch is

CALIBRATION Menu - Allows the balance to be calibrated by using either Auto, User or 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 parameters under which the balance will interface

to a computer or a printer.

Each of these menus contain selectable parameters which can be entered via the front panel 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

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

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.

INSTALLATION

RS232 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.

Hardware

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 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.

RS232 Commands

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).

Parts Counting

Parts Counting is menu. Refer to page 38. In the parts counting mode, the balance displays the quantity of parts you place on the pan. Since the balance determines the quantity based on the average weight of a single part, all parts must be reasonably uniform in weight. The accuracy of parts counting results is determined by the error level entered in PC Err of the Setup Options submenu. Refer to page 43. The default setting for PC Err is off.

To perform parts counting when in a weighing mode, use the following procedure:

when Animal Weighing Function is selected under the Setup menu. Refer to page 38. To set options, refer to page 46, Animal Weighing 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.

FILLGUIDE

INDICATOR

The FillGuideTM is a bar graph which appears in the upper right hand portion of the display. When the load on the balance is at the balance's capacity, all of the segments are on. When the load is at half capacity, only the first half of the segments are on. During normal operation of the balance, the bar graph displays the relationship between the load on the pan and the capacity of the balance. In the Fill Guide mode, the bar graph can be set to a desired target value. The FillGuide

feature can be used in any one of the available weighing units.

The Fill Option under the Setup Options submenu provides two choices for a reference weight (similar to check weighing). Either a mass can be placed on the pan and used as a reference weight or a number can be entered to establish the weight value. Both methods are used to establish a reference for a 100% bar graph reading. Target parameter provides two choices, one is fill to the reference, the other to zero weight and Target = to reference..

Check Weighing Options

Check Weighing is enabled only when the Check Weighing Function is selected. This feature may be used for check weighing or package weight control in any one of the available weighing units. When in use, the display will show the relationship between the load on the pan, and the selected target weight. The bar graph will visibly display where the weight of the load falls in relationship to the under, acceptable, and over limits. The balance also displays UNDER, ACCEPT, and OVER messages as appropriate. The default settings are: Reference = Reference weight, Display = normal.

Two choices are provided for programming the Reference Weight. One choice is the use of a mass (package, container, etc,) and the other is a number which can be entered as a high and low limit.

Three choices are provided for programming the display: normal, none, and sign. Sample displays are shown on the next page.
