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

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.

5.2 RS232 Interface

Explorer balances are equipped with a bi-directional
RS232 compatible interface f or communication with
printers and computers. When the balance is connected
directly to a printer, displa y ed data can be output at any
time by simply pressing PRINT, or b y using the Auto Print
feature.

Connecting the balance to a computer enables you to
operate the balance from the computer, as w ell as
receive data such as display ed w eight, weighing mode ,
stability status, etc.

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 sho wn
in the adjacent illustration.
The balance will not output any data unless pin 5 (CTS)
is held in an ON 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.

The output format is illustrated in the RS232 command
table which follows .

RS232 Connection

Rear of Balance

RS232 Commands

All communication is accomplished using standard ASCII
format. Characters sho wn in the following table are
acknowledged by the balance. Inv alid command re­sponse "ES" error indicates the balance has not recog­nized the command. Commands sent to the balance
must be terminated with a carriage return (CR) or
carriage return-line line feed (CRLF). F or example, a tare
command should appear as shown in the adjacent
diagram. Data output b y the balance is alw ays terminated
with a carriage return - line feed (CRLF).
