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.

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.

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.

2.3 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.

Leveling

Indicator

Leveling

Foot

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.

10

2.4 Installing Cover Plate and Pan

Balances in the range of 62g to 410g are shipped with the pan and the protective cover plate not installed. On balances equipped with a draft shield, slide open the side door and place the cover plate into position. Then, insert the pan into the center hole which is the measuring transducer. Higher capacity balances with 6" or 8" pans do not have a cover plate.

Pan

Cover Plate

2.5 Installing Wind Shield

Wind Shield

On 610g to 4100g balances with 0.01g 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: 4100g, 6100g and 8100g balances with internal calibration are equipped with a 6" Pan and Windshield.

2.6 Connecting Power

Connect the AC Adapter supplied to the three pin connector located at the rear of the balance.

The balance is now ready for operation.

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 our Product Service Department at [phone].

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

3.3 Calibration

Refer to paragraph 3.3 and calibrate the balance before proceeding.

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.

CALIBRATION MASSES

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.

Procedure

• Press the Setup button, CAL is displayed.

• Press Enter button, CAL TYPE is displayed.

• Press Enter button, CAL TYPE InCAL is displayed.

• Press Enter button, INCAL is displayed.

IMPORTANT !

DO NOT DISTURB THE BALANCE DURING

CALIBRATION. IF THE MESSAGE UNSTBLE

IS DISPLAYED,THE BALANCE WAS UNABLE

TO ACQUIRE STABLE DATA DURING INTER-

NAL CALIBRATION. THE BALANCE WILL

CONTINUE TO PERFORM INTERNAL CALI-

BRATION UNTIL READINGS STABILIZE. THE

BALANCE WILL THEN COMPLETE THE IN-

TERNAL CALIBRATION FUNCTION.

TO EXIT INTERNAL CALIBRATION MODE

BEFORE COMPLETION, PRESS ENTER OR

SETUP BUTTONS.

STABILITY CAN BE AFFECTED BY TEM-

PERATURE, AIR CURRENTS, VIBRATION,

ETC...

NOTE: If a weight is left on the pan, the balance will display CLR PAN (remove the weight from the pan). The balance automatically resumes calibration.

The internal mass is positioned several times during calibration and then removed, then after a few seconds, CAL SET is displayed indicating a successful calibration. The display then returns to WEIGH mode.
