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.

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 over the pan. Make sure the windshield is firmly
snapped into place.

Wind Shield

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, remove the
protective cover underneath the balance. See illustration for

location. The balance can be supported using lab jacks or any
other convenient method. Make sure the balance is level and

secure. Apply power and operate the balance. Attach items to be
weighed to the hook underneath the balance.

Explorer Pro EN-5

2.3 Selecting the Location

2.3.1 Balance Location

The balance should always be used in an environment which is
free from excessive air currents, corrosives, vibration, 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 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 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 leveled.

For exact horizontal positioning, the balance is equipped with a

level indicator located at the front on the control panel and two
leveling feet located at the rear of the balance.

Position the balance in the intended operating location. Adjust

the leveling feet at the rear of the balance until the air bubble in
the indicator is centered.

NOTE: The instrument should be leveled 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 receive data such as displayed weight,

weighing mode, stability status, etc.

Male Connector

The following sections describe the hardware and software
provided with the balance

Hardware

On the rear of the balance, the right-hand, 9-pin male subminiature
D connector is provided for interfacing to other devices. 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.

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 available. If you begin calibration and realize

calibration masses are not available, 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 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 available 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 have internal calibration, an external mass is required.

balances offers a choice of five calibration methods: Internal
Calibration, Autocal Calibration, Span Calibration, Linearity

Calibration and User Calibration,

IMPORTANT !

DO NOT DISTURB THE BALANCE

DURING CALIBRATION.

Internal Calibration

On Explorer Pro balances equipped with internal calibration,
calibration is accomplished using the internal calibration mass.

Internal calibration can be performed at any time providing the
balance has warmed up to operating temperature and is level.

AutoCal: On, Off (default is On)

Explorer Pro balances equipped with internal calibration also
contain AutoCal. When AutoCal is set ON, the balance performs

a self calibration when a measured predefined delta temperature
change occurs. After calibration, the display returns to the last

application mode. Environmental conditions must be met for the
AutoCal to be successfully completed.

AutoCal Delta: -100 - +100 (default is 0)

Explorer Pro balances equipped with internal calibration also

contain AutoCal Delta. AutoCal Delta allows the internal calibration

mass value to be adjusted. This permits calibrating the balance

using an external mass which is traceable to a certified standard.

Perform the internal calibration procedure. After the calibration is

completed, zero the balance.

Place a certified mass equal to the span calibration value of the

balance.

Linearity, Span and User calibration are disabled for Type
Approved/LFT balances Class II and Class III.

EN-24 Explorer Pro

Compare the reading on the balance to the expected weight being
used. If the reading is above the expected weight, the delta entered

in digits is negative. If the reading is below the expected weight,
the delta entered in digits is positive.

See following example:

Actual Weight Reading: 200.0014
Expected Weight Reading: 200.0000

Delta Weight (d): 0.0014
Delta weight in Digits: -14

Recalibrate using internal calibration. After calibration, place the

certified mass on the pan and see if the mass agrees with the

displayed value. If not, repeat procedure until internal calibration

reading agrees with the certified mass.

Span Calibration:

Span calibration utilizes two calibration points, one at zero load
and the other at specified full span. See following table.

6100 g 2000g/5000 g 5000 g

8100 g 4000g/8000 g 8000 g
It is recommended that masses must meet or exceed ASTM

Class 1 Tolerance. Calibration masses are available as
accessories.

Additional calibration values to be used are shown on the display

screen. The best accuracy is achieved using the mass closest
to the full span value. After calibration, the display returns to the

last application mode.

Linearity Calibration:

Linearity calibration utilizes three calibration points, one at zero
load and two at specified calibration masses. This method

minimizes deviation between actual and displayed weights within
the balance's weighing range. After calibration, the display returns

to the last application mode.

User Calibration:
User calibration is used when it is desired to calibrate the balance

using a user defined mass. The user defined mass value has to
be entered in the User Cal Weight. After calibration, the display

returns to the last application mode.

User Calibration Weight: 25%-100% of capacity (default is Span)
Defines the mass value for User calaibration. The user calibration

may now be done with the mass selected.

Cal Test:
Calibration test feature allows a check of a known calibration

mass against the last stored calibration information in the balance.

The display indicates the difference in weight between calibration
mass placed on the pan and the previous weight value which

was stored in the balance. After Cal Test, the display returns to to
the last application mode.
