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, Automatic

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.
1. INTRODUCTION

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.
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.

thermometer.
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
A density determination kit is designed to be used with Ohaus Explorer Semi-Mirco 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.

4.12 Pipette Adjustment
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.

Note: Do not disturb the balance during any calibration.
5.3.1 Calibration sub-menu
5.3.2 Internal Calibration (AutoCal™)
Calibration is accomplished with the internal calibration mass. Internal calibration can be performed at
any time, provided the balance has warmed up to operating temperature and is level.
With the Balance turned ON and no load on the pan, touch AutoCal™ Internal Calibration.
The Balance begins to calibrate.
Alternately, touch the shortcut Calibration Icon from any Application home screen
to initiate an Internal Calibration.
The display shows the status, then returns to the current application.
To cancel at any time, press Cancel.
5.3.3 Automatic Calibration
When Automatic Calibration is set ON, the balance performs a self calibration:
• when it senses a temperature change of 0.5°C
• or every 3 hours
AutoCal will automatically calibrate the Balance (using the internal mass) each time there is a change in
temperature significant enough to affect accuracy.

5.3.4 AutoCal™ Adjustment
Use this calibration method to adjust the zero calibration point, without affecting the span or linearity
calibration.
Calibration Adjust may be used to adjust the result of the Internal calibration by +100 divisions.
Note: Before making a calibration adjustment, perform an Internal Calibration. To verify whether an
adjustment is needed, place a test mass equal to the span calibration value* on the pan and note the
difference (in divisions) between the nominal mass value and the actual Balance reading. If the difference
is within +1 division, calibration adjustment is not required. If the difference exceeds +1 division,
calibration adjustment is recommended. (*See Table 5-1, below.)
Example:
Actual weight reading: 200.00014
Expected weight reading: 200.00000 (Test mass value)

To perform a Calibration Adjustment, touch AutoCal Adjustment from the Calibration Menu; Enter the
value (positive or negative divisions) to match the difference noted earlier in the procedure and press .
Recalibrate using Internal Calibration. After calibration, place the test mass on the pan and verify that the
mass value now matches the displayed value. If not, repeat the procedure until Internal Calibration
reading agrees with the test mass.
Once completed, the balance stores the Adjustment value and the display returns to the current
application.
5.3.5 Span Calibration
Span calibration uses two calibration points, one at zero load and the other at specified full load (span).
Refer to Table 5.1 for Span values. For detailed calibration mass information please see the specification
tables in section 9.
TABLE 5-1 Calibration Masses
With the balance turned ON and no load on the pan, touch Span Calibration to initiate the procedure.
Additional calibration values to be used are shown on the display. The best accuracy is achieved using
the mass closest to the full span value.
Note: To change the span calibration point, touch the alternate weight shown on the display.
Follow the screen instructions and place the specified calibration weight on the scale when prompted to
do so. When complete, the display shows the Span calibration status and returns to the current
application.
