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
eventyour instrument requiresservicing. OHAUS alsohasa Customer ServiceDepartment to answerany 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.
• Allowsufficientspacearound the instrument forease
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.
Forexact horizontal positioning, thebalanceis 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 bal-
ances 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, 6100gand 8100 g balanceswith internal
calibration are equipped with a 6" Pan and Windshield.

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
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

periodistwenty(20) minutes.Analytical Class I balances
require at least 2 hours. The internal circuits of the
balancearepoweredwhenever it is plugged intoapower
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.

Calibration Menu Protection
NOTES:
• Calibration may be locked out to prevent unautho-
rized personnel from changing calibration. If calibra-
tion 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. Ifyou begin calibration and realizecalibration
masses are not available, exit the menu. The balance

On Explorer balances equipped with the InCalTM feature, calibration can be accomplished using the internal cali-
bration 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.
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,
CALSETis displayed indicating asuccessfulcalibration.
The display then returns to WEIGH mode.
IMPORTANT !
DO NOT DISTURB THE BALANCE DURING
CALIBRATION. IFTHE MESSAGE UNSTBLE IS DIS-
PLAYED,THE BALANCEWAS UNABLETO ACQUIRE
STABLE DATA DURING INTERNAL CALIBRATION.
THE BALANCE WILL CONTINUE TO PERFORM
INTERNAL CALIBRATION UNTIL READINGS STABI-
LIZE. THE BALANCE WILL THEN COMPLETE THE
INTERNAL CALIBRATION FUNCTION.
TO EXIT INTERNAL CALIBRATION MODE BEFORE
COMPLETION,PRESS ENTER OR SETUP BUTTONS.
STABILITY CAN BE AFFECTED BYTEMPERATURE,

3.3.3 Calibration Adjust
Balanceswith InCalTM containsoftware which allowsthe
internal calibration mass to be adjusted + 100 divisions
atfull scale capacity.This permits calibrating the balance
using an external Class I mass which is traceable to a
certified standard.
Procedure
• Perform the internal calibration procedure of para-
graph 3.3.1.
• Press #button to zero the balance.
• Place a Class I mass equal to the span calibration
value of the balance. Note the reading on the bal-
ance and see if the balance indicates the exact
weight or indicates a higher or lower reading. If the
reading is higher or lower, proceed.
• Press the Setup button, CAL is displayed.
• Press Enter button, CAL TYPE is displayed.
• Press button until, CAL ADJ is displayed.
• Press Enter button, CAL ADJ 0 should be displayed
(0 is factory setting).
NOTE: Balance will retain last CAL ADJ setting.
• Press or button until desired number is
displayed.
• Press Enter button, SAVED is momentarily dis-
played, then display indicates LOCK.
• Press Enter button, LOCK ON or LOCK OFF is dis-
played.
• Press or button and select either LOCK
ON or LOCK OFF. LOCK ON is normally used in
legal for trade applications. When set ON, and legal
for trade is enabled in the balance, the calibration
adjust is disabled and whatever setting was entered
will remain in the balance.
• Press Enter button, SAVED is momentarily dis-
played, then EXIT is displayed.
• PressEnter button, display returnstoWEIGH mode.
• Perform the internal calibration procedure of para-
graph 3.3.1.The value entered as an adjustment is
now stored. Place the calibration mass on the pan
and check. Repeat procedure if further correction is
required.The display must agreewith themass used
for calibration.
• To return to factory setting, follow procedure above
and set CAL ADJ to 0.

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
balance

3.3.6 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 8.1 kg balance.
