1. GETTING TO KNOW YOUR BALANCE

Please read through this section carefully, as it contains important information for safe and economical operation

of your Explorer Balance.

1.1 Introduction

Thank you for deciding to purchase an Explorer Balance from Ohaus. Thanks to a new modular design, your

Explorer Balance lets you adapt the balance to your changing needs. Remote displays, upgraded displays which

can be table, wall or tower mounted are available as accessories. It offers a high level of operating convenience

and useful functions to make accurate measurements. A unique LCD panel has a large 7 digit, 7 segment display

which indicates the weight value of an item being measured and a 7 digit British Flag display (14 segments) which

spells out items selected in the submenus. In addition, the display contains English words to indicate the status of

the balance. Arrow indicators in the display prompt the user as to what panel keys are to be pressed to initiate a

change.

Panel controls are clearly marked as to their function with large Tare buttons on either side of the front panel.

Operation and setup of the balance is straightforward and easy. The Explorer Balance is available in a variety of

full scale capacities ranging from 62 grams to 8,100 grams with FineRangeTM range models available. Legal for

Trade versions are available.

Behind your instrument stands OHAUS, a leading manufacturer of precision scales and balances. 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 also has a Customer Service Department to answer any inquiries

regarding applications and accessories.

To ensure you make full use of the possibilities offered by your Explorer balance, we advise you to read through

these operating instructions very carefully.

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 equipment that generates

magnetic fields.

• On an unlevel work surface.

• Allow sufficient space around the instrument for ease

of operation and keep away from radiating heat

sources.

2.2 Selecting the Location

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.

2.3 Setting Up and Leveling the Balance

Exact horizontal positioning and stable installation are prerequisites for repeatable results. To compensate small

irregularites or inclinations at the location, the instrument can be leveled.

For exact horizontal positioning, the balance is equipped

with a level indicator located at the front on the control

panel 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.

Balances are shipped with the pan not installed. On balances equipped with a draft shield, slide open the side

door and insert the pan into the center hole which is the

measuring transducer.

Wind Shield

On 610 g to 4100 g balances with 0.01 g resolution, a

wind shield is required to reduce the possibility of air

currents from disturbing the pan. When the wind shield

is in place, air currents are deflected up over the pan.

Make sure the wind shield is firmly snapped into place.

NOTE: 4100 g, 6100 g and 8100 g balances with internal

calibration are equipped with a 6" Pan and Windshield.

3 OPERATING YOUR BALANCE

3.1 The Menu (Basic Settings of the Instrument)

The Explorer balance has three basic menus; each is selected by front panel buttons marked Mode, Units and

Setup.

Mode Button

The Mode button, when pressed, permits the selection of four weighing modes which are: weigh, percent, count

and animal weighing. These modes are controlled by an on or off selection made in the Setup menu under the

submenu Mode as displayed.

Units Button

The Units button, when pressed, allows the balance to display values in selected measuring unit.

Setup Button

The Setup button, when pressed, allows entry into thirteen submenus which allows you to set the balance for

specific operating parameters. Each of the thirteen submenus contain settings which are user selectable. The

table below illustrates the various submenus and the functions which are selectable. The items shown on the

menu, which are bolded, are the factory default settings. In other words, if you did not enter the Setup menu, the

balance would function in the basic manner shown by the various settings which are bolded. The setup submenus

shown below are arranged in the order as displayed in the balance.

3.2 Turning On the Balance

The Explorer balance is ready to operate after the installation procedures are performed. When the balance is first

turned on and it completes its checks, it can be used to weigh or tare materials without setting the menus.

It is recommended that you read this manual carefully and set the balance to operate for your specific applications

using the procedures in Chapter 4 Setting up Your Balance and calibrate the balance before using.

The balance is a high precision instrument and will give you years of service if kept clean and handled carefully.

If you have any problems operating the instrument or require additional information, please feel free to contact

Ohaus Corporation.

In this section, you will enter the menu for the first time. Do not worry if you are unfamiliar with the function of the

buttons on the panel, the display provides the necessary coaching as you go along.

Power On/Off

To turn the balance ON, press the ON/OFF button

(circled button with an I inside) located at the upper lefthand corner of the panel once. To turn OFF, press button

again.

Stabilization

Before initially using the balance, allow time for it to

adjust to its new environment. The balance only requires

to be plugged in to warm up. Recommended warm up

period is twenty (20) minutes. Analytical Class I balances

require at least 2 hours. The internal circuits of the

balance are powered whenever it is plugged into a power

source.

Calibration

Refer to paragraph 3.3 and calibrate the balance before

proceeding.

Stable 

 g

3.3 Calibration

Explorer balances offer a choice of five calibration methods: Internal Calibration (InCALTM), Span Calibration, User

Calibration, Linearity Calibration, and CalTestTM.

• InCal TM Internal calibration (InCALTM) of the balance is accomplished by an internal mass (If option is

installed). When CAL MSG is selected and set ON, CAL NOW is displayed when the balance

requires calibration. When CAL MSG is set OFF, the message CAL NOW is not displayed.

• Span - Span calibration ensures that the balance reads correctly within specifications using two

weight values: zero and a weight value at incremental values of full capacity and or 100 % of

the balance’s full capacity.

• User - User calibration is a method where the balance can be calibrated using a mass of known

value and by entering that numeric value into the balance.

• Linearity - Linearity calibration minimizes deviation between actual and displayed weights within the

balance’s weighing range. Three weight values are used: zero, a weight value at midpoint of

the balance's weighing range, and a weight value at or near the balance’s specified capacity.

• Cal Test - Calibration test allows the stored calibration data to be tested against the current mass being

used for the test.

• Lock - Can be set on or off. When set on, Span, User and Linearity are locked out and cannot be

used.

3.3 Calibration (Cont.)

Calibration Menu Protection

NOTES:

• Calibration may be locked out to prevent unauthorized personnel from changing calibration. If calibration has been locked out, you can only access Cal

Test and when installed, Internal Calibration

(InCALTM) .

• To lock out calibration menu, after calibration, refer

to the section titled Menu Lock-Out Protection.

Calibration Masses

Before beginning calibration, make sure masses are

available. If you begin calibration and realize calibration

masses are not available, exit the menu. 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 adjacent table.

NOTE:

Any of the calibration modes can be terminated at any

time by pressing either the Mode, Units or Setup

buttons.

3.3.1 Internal Calibration (InCALTM)

On Explorer balances equipped with the InCalTM feature, calibration can be accomplished using the internal calibration mass. When the balance requires calibration, a screen prompt of CAL NOW appears. This display can be

turned off as described in paragraph 3.3.2. Also, a software adjust feature is incorporated which permits the

internal calibration mass to be adjusted to +100 counts. The adjust feature is described in paragraph 3.3.3. Internal

calibration can be performed at any time providing the balance has warmed up to operating temperature.

3.3.4 Span Calibration

Span calibration utilizes two calibration points, one at zero and the other at full span or incremental values starting

at 25 % of full capacity. As an example, an 8.1 kg balance will accept either 2 kg, 4 kg, 6 kg or 8 kg for span

calibration. Values which are below or in between will not be accepted and the balance will display its maximum

capacity. When LFT is set on, only full span calibration value can be used. Sample display illustrates an 8.1 kg

Stability

The stability range specifies the weighing results and must be within a preset tolerance limit for a certain time to

turn the stability indicator ON. When a displayed weight changes beyond the allowable range, the stability indicator

turns OFF, indicating an unstable condition. Factory default setting is shown in bold type.

.5 d Smallest range: stability indicator is ON only when displayed weight is stable within

.5 divisions.

1 d Reduced range.

2 d Normal range.

5 d Largest range, stability indicator is ON even though displayed weight changes slightly.

When the RS232 interface is configured to print stable data only, the stability range also governs data output.

Displayed data will only be output if it is within the selected stability range.

Auto-Zero

Auto-Zero minimizes the effects of temperature changes and shift on the zero reading. The balance maintains the

zero display until the threshold is exceeded. Factory default setting is shown in bold type.

OFF Turns Auto-Zero OFF.

.5 d Sets threshold to .5 divisions.

1 d Sets threshold to 1 division.

3 d Sets threshold to 3 divisions.

Filter

Filter compensates for vibration or excessive air currents. Default settings are shown bold.

-0- reduced stability, fastest stabilization time

-1- normal stability, normal stabilization time

-2- more stability, slow stabilization time.

-3- maximum stability, slowest stabilization time.

5.2 RS232 Interface

Explorer balances are equipped with a bidirectional

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, the right-hand, 9-pin male

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. Characters shown in the following table are

acknowledged by the balance. Invalid command response "ES" error indicates the balance has not recognized the command. 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).
