2.2 Installing Components
2.2.1 Platform Installation
Balances are shipped with the pan not installed. On balances
equipped with a draft shield, slide open the side door and insert
the pan into the center hole.
Wind Shield
2.2.2 Windshield Installation
On 610 g to 6100 g balances with 0.01 g resolution, a wind-
shield is required to reduce the possibility of air currents from
disturbing the pan. When the windshield is in place, air currents
are deflected up o er the pan. Make sure the windshield is firmly
snapped into place.
NOTE: 4100 g, 6100 g and 8100 g balances with internal
calibration are equipped with a 6" Pan and Windshield.
2.2.3 Weigh Below Preparation
The Explorer Pro balance is equipped with a weigh below hook
at the bottom of the balance. To use this feature, remo e the
protecti e co er underneath the balance. See illustration for
location. The balance can be supported using lab jacks or any
other con enient method. Make sure the balance is le el and
secure. Apply power and operate the balance. Attach items to be
weighed to the hook underneath the balance.

2.3 Selecting the Location
2.3.1 Balance Location
The balance should always be used in an en ironment which is
free from excessi e air currents, corrosi es, ibration, and
temperature or humidity extremes. These factors will affect
displayed weight readings.
DO NOT install the balance:
 Next to open windows or doors causing drafts or rapid
temperature changes.
 Near air conditioning or heat ents.
 Near ibrating, rotating or reciprocating equipment.
 Near magnetic fields or equipment that generates magnetic
fields.
 On an unle el work surface.
 Allow sufficient space around the instrument for ease of
operation and keep away from radiating heat sources.
2.3.2 Leveling the Balance
Exact horizontal positioning and stable installation are
prerequisites for repeatable results. To compensate for small
irregularities or inclinations at the location, the instrument can
be le eled.
For exact horizontal positioning, the balance is equipped with a
le el indicator located at the front on the control panel and two
le eling feet located at the rear of the balance.
Position the balance in the intended operating location. Adjust
the le eling feet at the rear of the balance until the air bubble in
the indicator is centered.
NOTE: The instrument should be le eled each time its location is
changed.

2.4 Connecting Power and Communications
2.4.1 AC Adapter Installation
Connect the AC Adapter supplied to the three pin connector located
at the rear of the balance.
The balance is now ready for operation.
AC Adapter Connection
Rear of Balance
2.4.2 RS232 Interface
Explorer Pro balances are equipped with a bidirectional RS232
compatible interface for communication with serial printers and
computers. When the balance is connected directly to a printer,
displayed data can be output at any time by simply pressing the
Print button, or by using the Auto Print feature. Connecting the
balance to a computer enables you to operate the balance from
the computer, as well as recei e data such as displayed weight,
weighing mode, stability status, etc.
The following sections describe the hardware and software
pro ided with the balance
Hardware
On the rear of the balance, the right-hand, 9-pin male subminiature
D connector is pro ided for interfacing to other de ices. The
pinout and pin connections are shown in the adjacent illustration.
Refer to paragraph 3.5.6 for setup.
The balance is equipped with hardware handshaking, it will not
output any data unless pin 5 (CTS) is held in a high state (+3 to
+15 V dc). Interfaces not utilizing the CTS handshake may tie pin
5 to pin 6 to defeat it.
Output Formats
Data output can be initiated in one of three ways: 1) By pressing
PRINT; 2) Using the Auto Print feature; 3) Sending a print
command (P) from a computer.
Additional information is located in Section 5, Technical Data

2.4.3 Initial Calibration
Calibration Masses
Calibration masses are required if the balance is not equipped
with internal calibration. Before beginning calibration, make sure
masses are a ailable. If you begin calibration and realize
calibration masses are not a ailable, exit the menu. The balance
will retain pre iously stored calibration data. Calibration should
be performed as necessary to ensure accurate weighing. Masses
required to perform the procedures are listed in the following table.
NOTE: Any of the calibration modes can be terminated at any
time by pressing the Menu button.

It is recommended that masses must meet or exceed ASTM
Class 1 Tolerance. Calibration masses are a ailable as
accessories.
Calibrating from the Weighing Screen
When the balance is first turned on, three soft keys appear on
the weighing screen. The CALIBRATE soft key is highlighted.
This permits calibration immediately without entering the
CALIBRATION menu. On balances equipped with internal
calibration, the balance automatically calibrates. On balances
that do not ha e internal calibration, an external mass is required.

parts you place on the pan. Since the balance determines the
quantity based on the a erage weight of a single part, all parts
must be reasonably uniform in weight.
The balance has a default setting of 10 pieces. This permits
starting parts counting immediately without setting up the balance.
The following display indicates the first time operation of parts
counting.
