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.

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.

2.5 Wind Shield
On 610 g to 6100 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.
Wind Shield
NOTE: 4100 g, 6100 g and 8100 g balances with 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 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

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.
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.

5.2 RS232 Interface
RS232 Connection
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
Rear of 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.
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).
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

5.3 Error Codes List
Error Codes List
The following list describes the various error codes and which can appear on the display and the suggested
remedy.
Data Errors
1.0
Transient error (hardware error, probably static discharge). If error persists, the balance must be
serviced.
1.1
Balance temperature transducer hardware error.
Tare Errors
2.0
Balance is unable to stabilize within time limit after taring. Environment is too hostile or balance needs
recalibration.
Calibration Errors
3.0
Incorrect or no calibration mass used for calibration. Recalibrate with correct masses.
RS232 Errors
4.4
RS232 buffer is full.
User Errors
7.0
User entry out of bounds.
7.2
Number outside of display capacity.
Over-Under Load Errors
8.0
Hardware error causing an internal weight signal which is too low. Check if pan is off. If not, the balance
must be serviced.
8.1
Hardware error caused by an internal weight signal which is too high. Check load on the pan which may
be excessive. If error persists, the balance must be serviced.
8.2
Power-on load out of specification (LFT only)
8.3
Rated capacity exceeded. Remove excessive weight from pan.
8.4
Underload condition on balance. Check that the proper pan is installed.
8.5
Internal calibration weight internal sensor indicated its weight on the pan.
CheckSum Errors
9.1
Bad factory checksum. If error persists, have the balance serviced.
9.2
Bad factory checksum. If error persists, have the balance serviced.
9.3
Bad factory checksum. If error persists, have the balance serviced.
9.4
Factory internal calibration data failed checksum. This failure will disable access to the InCALTM feature
(if installed).
9.5
Factory calibration data failed checksum.
9.8
User calibration data failed checksum.
9.9
Factory temperature compensation data failed checksum.
5.4 Information Messages

LOW REF
UNSTBLE
If InCALTM (internal calibration) is installed. Message to recalibrate the balance. The
message will remain until calibrated.
The user tried to perform an internal calibration and this message will be flashed in the 14
segment field. The balance requires a 7 minute warmup period. During warmup the user
can not select InCALTM from the menu.
This message is flashed when an item is changed in the menu and the new value is
written to the EEPROM.
This message is flashed when an item can not be changed in the menu because the
menu is locked and the Lock Switch is set locked.
The message is flashed in parts counting or percent when the calculated reference weight
is very low.
This message is flashed when the balance was unable to aquire stable data during internal
calibration.
