1. GETTINGTO KNOWYOUR 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 largeTare buttons on either side of the front panel. Opera-
tion and setup of the balance is straightforward and easy. The Explorer Balance is available in full scale capacities of
12,000 grams, 22,000 grams and 32,000 grams. 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

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 rear of the balance
and leveling feet located at the front and rear of the
balance.
Position the balance in the intended operating location.

3 OPERATINGYOUR 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 func-
tion in the basic manner shown by the various settings which are bolded. The setup submenus shown below are

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 upYour 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 left-
hand 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 thirty (30) minutes.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.
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.)
NOTE:When CAL NOW is displayed, the balance should be calibrated before weighing
again.
• 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 balances weighing range, and a weight value at or near the balance’s specified capacity.
• CalTest - 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 Internal Calibration
(InCALTM) when installed and CalTest.
•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.

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.
After a few seconds, CAL SET is displayed (the internal
weight is positioned and then removed), the display
then returns toWEIGH mode.
NOTE:
DO NOT DISTURBTHE BALANCE DURING
CALIBRATION.

3.3.2 Span Calibration
Span calibration utilizes two calibration points, one at zero and the other at full span or incremental values starting at
approximately 25% of full capacity. As an example, an 12kg balance will accept either 4kg, 6kg, 8kg, or 10kg for span
calibration. Values which are below or in between will not be accepted and the balance will display its maximum
capacity. Sample display illustrates an 12kg balance Procedure
• Press the Setup button, CAL is displayed.
• Press Enter button, CALTYPE is displayed.
• Press Enter button, CALTYPE InCAL is displayed.
• Press button to select SPAN calibration, CAL
TYPE SPAN is displayed.
• Press Enter button,WORKING is displayed.
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.
• Display changes to PUT WT 10000g.
• Place specified calibration mass on pan.
NOTE:For an 12kg balance, either 4kg, 6kg, 8kg, or
10kg can be used for span calibration. The PUT
WEIGHT message indicates the calibration mass that
is on the pan.
• Press Enter button, WORKING is displayed. After a
few seconds CAL SET is displayed, the display then
returns toWEIGH mode.
Span calibration is completed.
• Remove calibration mass from the pan.

3.3.3 User Calibration
User calibration is used when it is desired to calibrate the balance using a mass of known value. To use this calibra-
tion feature, proceed as follows:
(FLASHING)
• Press the Setup button, CAL is displayed.
• Press Enter button, CALTYPE is displayed.
• Press Enter button, CALTYPE InCAL is dis -
played.
• Press button twice to select USER calibration,
CAL TYPE USer is displayed.
• Press Enter button, the display indicates the last
calibration mass value which was entered with the
first digit flashing. (Sampleillustrates 6000g).
• Press and or and enter the
desired mass value. This number must be at least
25% of the full span value.
• Press Enter button,WORKING is displayed.
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.
• Display changes to PUT WT 6000g.
• Place specified calibration mass on pan.
• Press Enter button, WORKING is displayed. After a
few seconds CAL SET is displayed, the display then
returns toWEIGH mode.
User calibration is completed.
• Remove calibration mass from the pan.

Procedure
• Press the Setup button, CAL is displayed.
• Press Enter button, CALTYPE is displayed.
• Press Enter button, CALTYPE InCAL is displayed.
• Press button three times to select LIN calibra-
tion, CALTYPE Lin is displayed.
• Press Enter button,WORKING is displayed.
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.
• Display changes to PUT WT 5000 g. The displayed
weight is half the capacity of the balance.
• Place specified calibration mass on pan.
• Press Enter button, WORKING is displayed. After a
few seconds display changes to PUTWT 10000 g.
• Place specified calibration mass on pan.
• Press Enter button, WORKING is displayed. After a
few seconds CAL SET is displayed, the display then
returns toWEIGH mode.
Linearity calibration is completed.
• Remove calibration mass from the pan.
3.3.4 Linearity Calibration
Linearity calibration utilizes three calibration points, one at zero, center span and full span. This method 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 specified capacity.
Sample display illustrates an 12kg balance.

3.3.5 CalibrationTest
Calibration test feature allows a check of a known calibration mass against the last stored calibration information in
the balance. Sample display illustrates an 12kg balance.
Procedure
• Press the Setup button, CAL is displayed.
• Press Enter button, CALTYPE is displayed.
• Press Enter button, CALTYPE InCAL is displayed.
• Press button to select CALTEST calibration,
CALtESt is displayed.
• Press Enter button,WORKING is displayed.
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.
• Display changes to PUT WT 10000 g.
• Place specified calibration mass on pan.
• Press Enter button,WORKING is displayed. After a
few seconds,WEIGH DIFF is displayed. The display
now indicates the actual difference in weight between
what value was just placed on the pan and the
previous weight value which was stored in the bal-
ance. After approximately 8 seconds,the display
returns to theWEIGH mode.
• Remove calibration test mass from the pan.
