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 35,000 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, Ionizer+Tare, Automatic
draftshield door, ionizer etc.
Statistics: available in Weighing, Counting, Percent
Weighing, Check Weighing, Dynamic Weighing, Filling.
Ionizer (EX225D/AD and EX225/AD only)
The Ionizer generates bipolar ions continuously by DC corona
discharge separately from positive and negative discharge electrodes
and directs the ionized air onto the charged body to eliminate static
electricity. The generated ions are well-balanced in polarity and can
eliminate static electricity regardless of the polarity of the charged
body.
Static electricity
Generally, insulators such as plastics are prone to be charged with
static electricity when the ambient relative humidity is below 45%RH.
This may affect weighing and cause a measurement error of several
milligrams. The Ionizer can eliminate static electricity very effectively.
How to activate the Ionizer
The Ionizer can be activated or turned off by either the touchless sensors (see section 5.4.9) or through the
function icons by pressing the Ionizer icon on the application home screen.

Explosion hazard
Safety Notes
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.
Operate the equipment only under ambient conditions specified in these instructions.
Do not operate the equipment in wet, hazardous or unstable environments.
Use only approved accessories and peripherals.
Service should only be performed by authorized personnel.
If the equipment is used in a manner not specified by the manufacturer, the protection provided by
the equipment may be impaired.
This equipment is for indoor use only.
Do not place the equipment upside down on the platform.
Dry off any liquid spills immediately! The instrument is not watertight.
Do not immerse the equipment in water or other liquids.
Only connect the power cord to a compatible grounded electrical outlet.
Make sure that the power cord does not pose a potential obstacle or tripping hazard.
Verify that the AC adapter's input voltage range and plug type are compatible with the local AC
mains power supply.
Do not position the equipment such that it is difficult to reach the power connection.
Ensure that vibrations due to machinery near the installation site are kept to a minimum.
Only use weights within the scale's capacity as specified in these instructions.
Do not drop loads on the platform.
Use your scale with care, gently loading items to be weighed onto the center of the pan. Avoiding
rough treatment will aid in the life of your scale.
For best results, use the equipment in the specified optimum operating temperature.
WARNING: When using chemicals and solvents, comply with the instructions of the producer and the
general lab safety rules.
WARNING: Never work in an environment subject to explosion hazards! The housing of the instrument is
not gas tight. (Explosion hazard due to spark formation, corrosion caused by the ingress of gases).
CAUTION: Battery is to be replaced only by an authorized Ohaus service dealer. Risk of explosion can
occur if the rechargeable battery is replaced with the wrong type or if it is not properly connected. Dispose of
the rechargeable battery according to local laws and regulations.
Safety precautions for the Ionizer:
WARNING: ELECTRICAL SHOCK HAZARD
AVOID TOUCHING THE ELECTRODE PINS WHILE THE IONIZER IS TURNED ON.

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 Semi-Micro models

EXPLORER BALANCES EN-11
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.

2.8Remote 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.

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.
