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.

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.

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 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
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/cc. 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).

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

5.3.3 Automatic Calibration
When Automatic Calibration is set ON, the balance performs a self calibration when a measured
predefined change occurs (in temperature or time). AutoCal will automatically calibrate the Balance (using
the internal mass) each time a change in temperature significant enough to affect accuracy, or after every
11 hours.
EN-90 EXPLORER BALANCES
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: 200.014
Expected weight reading: 200.000 (Test mass value)
Difference Weight (d): 0.014
Difference weight in digits: –14 (Adjust 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 9.
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.
Note: Factory default settings are shown in bold.

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.

5.3.6 User Calibration
User Calibration is used to calibrate the balance using a user defined mass.
With no load on the scale, press User Calibration from the calibration sub-menu.
The display shows the current full load (span) calibration point and calibration unit of measure.
To change the value to a user-defined weight, touch ENTER VALUE.
Enter the weight via the popup screen. The balance then prompts for the User-defined weight.
Place the specified calibration weight on the balance and the calibration process completes.
The display shows status, then returns to the current application.

Use Calibration Test to compare a known calibration weight against the stored span calibration data.
With no load on the scale, press Cal Test to begin the process.
The balance captures the zero point, then prompts for the span value.
The display shows status, followed by the difference between the current calibration weight and the
stored calibration data.
