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.

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.

4.10 Density Determination
The Explorer can be used to determine an object’s density. Four types of density determination can be made:
1. Solids more dense than water
2. Solids less dense than water
3. Liquid density
4. Porous material (impregnated with oil)
A density determination kit is designed to be used with Ohaus Explorer balances. Illustrations in this procedure
refer to the density kit. However, you may use whatever lab apparatus that suits the requirements for density
measurements. The balance software includes a built-in reference density table for water at temperatures
between 10°C and 30°C. Review this entire section before attempting density measurements.
When making density measurements the material should weigh at least 10 mg on an analytical balance and 100
mg on a precision balance.
Density can be determined manually (with a key press after each step) or automatically (weights are
automatically recorded). Before making density measurements, establish the Application Settings.

4.13 Pipette Adjustment (not available in EX12001, EX24001, EX35001)
Pipette adjustment checks the accuracy and precision values of pipettes by weight analysis. The balance has a
built-in density reference table for water at temperatures between 10°C and 30°C. If other liquids are used for
pipette calibration, enter the liquid’s density at current room temperature in g/cm3. Since all calculations are made
within the balance, the atmospheric pressure is also required.
Pipette adjustment can be accomplished manually (with a key press after each step) or automatically (weights
are automatically recorded when stable). Calculations made within the balance provide results of inaccuracy and
imprecision. Up to 30 samples can be used.

4.14 Statistical Quality Control (SQC)
The Statistical Quality control (SQC) feature is useful during various types of process filling operations, to monitor
and/or control the process to eliminate under- and over-filling.
As samples are weighed and stored in the balance, a Trend Analysis is developed and can be displayed.
Up to 10 batches with up to 80 samples in a batch are visible for quality control purposes. Each batch of samples
is shown, with the maximum, minimum, standard deviation and mean values for each batch. An on-going
examination of the relative deviation of the samples along with other statistical data can be viewed.
The filling process operation can be effectively monitored by observing the results on the View Trace screen.
SQC collection can be done manually (Manual mode, requires key press after each step) or
automatically (Auto Mode, the weights are automatically recorded when stable).
In the upper left portion of the home screen, select SQC.
