1.INTRODUCTION

1.1Description

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.

1.2Features

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.

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.
