out items selected in the submenus. In addition, the display contains English words to indicate the status of the
balance. Arro w indicators in the display prompt the user as to what panel keys are to be pressed to initiate a change .
Panel controls are clearly marked as to their function with large Tare buttons on either side of the front panel. Opera­tion and setup of the balance is straightforward and easy. The Explorer Balance is a v ailable in a variety of full scale
capacities ranging from 62 grams to 8,100 grams with FineRangeTM range models available . Legal for Trade versions

2.2 Selecting the Location

The balance should always be used in an en vironment which is free from e xcessive air currents, corrosives, vibration,
and temperature or humidity extremes. These factors will affect display ed w eight readings.

DO NOT install the balance:

• Next to open windows or doors causing drafts or
rapid temperature changes.

• Near air conditioning or heat vents.

• Near vibrating, rotating or reciprocating equipment.

• Near magnetic fields or equipment that generates

magnetic fields.

• On an unlevel work surface.

• Allow sufficient space around the instrument for

ease of operation and keep awa y from radiating heat
sources.

2.3 Setting Up and Leveling the Balance

Exact horizontal positioning and stable installation are prerequisites for repeatab le results . To compensate small
irregularites or inclinations at the location, the instrument can be leveled.

For exact horizontal positioning, the balance is equipped
with a level indicator located at the front on the control
panel and two leveling f eet located at the rear of the
balance.

Position the balance in the intended operating location.
Adjust the leveling f eet at the rear of the balance until the

NOTE: The instrument should be leveled each time its

location is changed.

2.4 Installing Cover Plate and Pan

Pan

Cover Plate

2.5 Installing Wind Shield

Wind Shield

Balances in the range of 62g to 410g are shipped with
the pan and the protective cov er plate not installed. On
balances equipped with a draft shield, slide open the side
door and place the cover plate into position. Then, insert
the pan into the center hole which is the measuring
transducer. Higher capacity balances with 6" or 8" pans
do not have a cover plate.

On 610g to 4100g balances with 0.01g resolution, a wind
shield is required to reduce the possibility of air currents
from disturbing the pan. When the wind shield is in
place, air currents are deflected up over the pan.
Make sure the wind shield is firmly snapped into place.

2.6 Connecting Power

AC Adapter Connection

Rear of Balance

NOTE: 4100g, 6100g and 8100g balances with internal
calibration are equipped with a 6" Pan and Windshield.

Connect the AC Adapter supplied to the three pin con­nector located at the rear of the balance.

The balance is now ready for operation.

3.3 Calibration

Explorer balances offer a choice of five calibration methods: Internal Calibration (InCALTM), Span Calibration, User
Calibration, Linearity Calibration, and CalTestTM.

Calibration Menu Protection

NOTES:

• Calibration may be lock ed out to prevent unauthorized
personnel from changing calibration. If calibration has
been locked out, y ou can only access Cal Test and when
installed, Internal Calibration (InCALTM) .

• To lock out calibration menu, after calibration, refer to the
section titled Menu Lock-Out Protection.

Calibration Masses

Before beginning calibration, make sure masses are
availab le. If you begin calibration and realize calibration
masses are not availab le, exit the menu. The balance will
retain previously stored calibration data. Calibration
should be performed as necessary to ensure accurate
weighing. Masses required to perform the procedures are
listed in the adjacent table.

NOTE:

Any of the calibration modes can be terminated

ASTM Class 1 Tolerance. Calibration masses are
available as accessories.

3.3.1 Internal Calibration (InCALTM)

On Explorer balances equipped with the InCalTM feature, calibration can be accomplished using the internal calibration
mass. When the balance requires calibration, a screen prompt of CAL NOW appears. This display can be turned off
as described in paragraph 3.3.2. Also, a software adjust feature is incorporated which permits the internal calibration
mass to be adjusted to +100 counts. The adjust feature is described in paragraph 3.3.3. Internal calibration can be
performed at any time providing the balance has warmed up to operating temperature.

Procedure

• Press the Setup button, CAL is displayed.

• Press Enter button, CAL TYPE is displayed.

• Press Enter button, CAL TYPE InCAL is displa yed.

• Press Enter button, INCAL is displayed.

IMPORTANT !
DO NOT DISTURB THE BALANCE DURING
CALIBRA TION. IF THE MESSAGE UNSTBLE
IS DISPLA YED , THE BALANCE W AS UNABLE
TO ACQUIRE STABLE DATA DURING INTER­NAL CALIBRATION. THE BALANCE WILL
CONTINUE TO PERFORM INTERNAL CALI­BRA TION UNTIL READINGS ST ABILIZE. THE
BALANCE WILL THEN COMPLETE THE IN­TERNAL CALIBRATION FUNCTION.

TO EXIT INTERNAL CALIBRATION MODE
BEFORE COMPLETION, PRESS ENTER OR
SETUP BUTTONS.

STABILITY CAN BE AFFECTED BY TEM­PERATURE, AIR CURRENTS, VIBRATION,
ETC...

NOTE: If a weight is left on the pan, the balance will

display CLR PAN (remov e the w eight from the pan).
The balance automatically resumes calibration.

The internal mass is positioned sev eral times during
calibration and then removed, then after a few sec­onds, CAL SET is displayed indicating a successful
calibration. The display then returns to WEIGH mode.
