1. INTRODUCTION
1.1 Description
The Explorer balance is a precision weighing instrument that will provide you with years of service if properly cared
for. The Ohaus Explorer balances are available in capacities from 120 grams to 10,200 grams.
1.2 Features
Modular Design: Ohaus Explorer balances are composed of two interconnected modules: a Terminal and a Base.
Depending on the user’s needs, the unit can be operated with the Terminal either attached to, or remote from, the
Base, with a single interconnect cord 1 meter long.
Touch Controls: Quick, graphical access to all control
functions, over a dozen applications and many features.
Touchless Sensors: can be assigned functions when
activated: Zero, Print, Tare, etc.
Statistics: available in Weighing, Counting, Percent
Weighing, Check Weighing, Dynamic Weighing, Filling,
Density Determination, Pipette Adjustment and
Statistical Quality Control applications.
1.3 Safety Precautions
Caution: Read all safety warnings before installing, making connections, or servicing this
equipment. Failure to comply with these warnings could result in personal injury and/or
property damage. Retain all instructions for future reference.
• Verify that the input voltage range printed on the data label and the plug type matches the local AC power
to be used.
• Make sure that the power cord does not pose a potential obstacle or tripping hazard.
• Use the balance only in dry locations.
• Do not drop loads on the pan.
• Use only approved accessories and peripherals.
• Operate the equipment only under ambient conditions specified in these instructions.
• Disconnect the equipment from the power supply when cleaning.
• Do not operate the equipment in hazardous or unstable environments.
• Service should only be performed by authorized personnel.

2.2 Installing Components
Refer to the illustrations and instructions below to identify and assemble your Explorer balance with its
components. All components must be assembled before using the balance.
2.2.1 Terminal Setup
When the Explorer is delivered, the Terminal is already attached (docked) to the Base. No additional setup is
necessary. However, for Draft Shield models, the Terminal needs to be detached temporarily in order to assemble
parts of the Draft Shield. Refer to the illustrations and instructions below to identify and assemble your Explorer
Balance.
Note: The Terminal is identical for all Explorer Balance models.
2.2.2 Installing the Wind Ring, Weighing Platform on Models EX124, EX224, and EX324
Note: Assembly instructions also apply to models with the suffix M or N.
1. Place the Wind Ring in position.
2. Insert the Platform Assembly
onto the Mounting Cone located
in the center of the Balance.
2.2.3 Installing the Sub-Platform and Weighing Pan on Models EX223, EX423, EX623 and EX1103
1. Place the Sub-platform in
position.
2. Position the Platform on the
Sub-platform.

2.2.4 Installing the Draft Shield Glass and Doors on Draft Shield Models
1. Carefully remove each of the four glass Draft Shield sections from the packaging.
NOTE: Before installing side doors, be sure to set the lock tabs in the proper position, as shown here.

EXPLORER BALANCES EN-9
2.2.5 Installing the Weighing Pan & Wind Shield – Non-Draft Shield Models
Note: Assembly instructions also apply to models with the suffix M or N.
1. Place the four Support Caps onto the Balance as shown.
2. Place the Weighing Pan on the Support Caps
3. Place the Wind Shield onto the Balance as shown.
Note: The balance can be operated without the Wind Shield. However, depending on ambient conditions the
displayed results may be slightly less stable.
2.3 Selecting the Location
Avoid excessive vibrations, heat sources, air current, or rapid temperature changes. Allow sufficient space.
Note: Interface cables connect to the terminal. The terminal can be detached and mounted on a wall or
positioned on a table separate from the balance.
2.4 Leveling the Equipment
The Explorer has an illuminated level indicator as a reminder that the balance should
be leveled for accurate weighing. There is a level bubble in a small round window on
the front of the Base. To level the balance, adjust the Leveling Thumbwheels at each
corner until the bubble is centered in the circle.
Be sure the equipment is level each time its location is changed.
Note: The feet cannot rotate. The Thumbwheels must be used for leveling.
See the Level Assist screen in the Information Menu.
To see the Level Assist menu, touch
More on the bottom-right corner of the
main screen. Then touch Level Assist.
The Level Assist screen shows which
direction to turn the thumbwheels to
center the level bubble.
EN-10 EXPLORER BALANCES
2.5 Connecting Power
2.5.1 AC Adapter
Connect the power cord of the AC Adapter (supplied) to the power receptacle on the rear of the Base.
Then connect the AC adapter plug to a suitable electrical outlet.
Caution: For use with CSA certified (or equivalent approved) power source,
which must have a limited current output.
Note: Allow equipment to warm up for 60 minutes for optimal weighing performance.
Standby: When unit is plugged in, it starts in Standby mode. Press the Standby icon to start.
2.6 Connecting the Interface
Use the built-in RS-232 (10101) Port to connect either to a
computer or a printer with a standard (straight-through) serial
cable. Or connect using the scale’s USB port.
Note: For configuration and interface commands, see the
Communication Menu Settings section.
For Connecting, Configuring and Testing the Printer/Computer
Interface, and for sample Print Output Formats, see the Printing
section.
Interface connections on back of Terminal.
Thread printer cable along cable coils on bottom of balance. Or pass cable through groove near release button.
2.7 Adjusting the View Angle of the Terminal
To adjust the Terminal display’s viewing angle, press in the Terminal Adjust buttons on both sides of the Terminal.
EXPLORER BALANCES EN-11
2.8 Remote Terminal Operation
The Terminal communicates with the weighing base via the Terminal cable. This cable must be plugged into the
Terminal for the Explorer to display properly. If desired, the Explorer balance may be operated either with the
Terminal attached (as-shipped), or remotely (up to 1 meter away).
2.8.1 Separating the Terminal from the Weighing Base
1. To detach, press both the Release buttons inward (both at the same time) and gently pull the Terminal
towards you (outward) until the Terminal is detached. These Release buttons disengage the two hooks
holding the Terminal to the Base. A cable is attached to the Terminal. Take care to not damage or
disconnect this cable.
2. To reattach the Terminal, press in the two Release buttons and slide the Terminal into the Base until the
Terminal hooks click and engage to hold the Terminal in place.
Release Button Base and Terminal Terminal Cable
Note: If a longer operation distance is required, a Terminal Extension cable is available as an accessory.
2.8.2 Terminal Mounting
If desired, the Terminal may be mounted to a wall or table using fasteners (not supplied) that are appropriate for the
type of mounting surface The Terminal bracket will accommodate 4mm (#8) screws. Locate the mounting holes as
shown in Figure 2-1.

2.9 Initial Calibration
When the Balance is first installed, and when it is moved to another location, it must be calibrated to ensure
accurate weighing results. The Explorer Balances have built in AutoCal which can calibrate the balance
automatically and does not require calibration masses. If preferred, the balance can be manually calibrated with
external masses. Have the appropriate calibration masses available before beginning calibration. Refer to the
Calibration Section for masses and calibration procedure.

Each time a new type of part is counted, the nominal weight of
one piece (Average Piece Weight or APW) must be established
using a small quantity of pieces. This APW is stored until
replaced by another APW.
There are two methods to establish the APW value:
1. The actual APW is known; or
2. The APW must be derived by weight. For this case the
current sample size will be used
