this equipment. Failure to comply with these warnings could result in personal injury
and/or property damage. Retain all instructions for future reference.
1. INTRODUCTION
1.1 Description
The Scout STX balance is a high quality weighing instrument that will provide you with years of
service if properly cared for. Models are available with ranges from 120g to 8200g.
1.2 Definition of Signal Warnings and Symbols
Safety notes are marked with signal words and warning symbols. These show safety issues and
warnings. Ignoring the safety notes may lead to personal injury, damage to the instrument,
malfunctions and false results.
Signal Words
WARNING For a hazardous situation with medium risk, possibly resulting in injuries or
death if not avoided.
CAUTION For a hazardous situation with low risk, resulting in damage to the device or
the property or in loss of data, or injuries if not avoided.
Attention For important information about the product.
Note For useful information about the product.
Warning Symbols
1.3 Safety Precautions
Verify that the input voltage range printed on the data label and the plug type matches
the local AC power to be used.
Make sure that the power cord does not pose a potential obstacle or tripping hazard.
Use the balance only in dry locations.
Do not drop loads on the pan.
Use only approved accessories and peripherals.
Operate the equipment only under ambient conditions specified in these instructions.
Disconnect the equipment from the power supply when cleaning.
Do not operate the equipment in hazardous or unstable environments.
Service should only be performed by authorized personnel.
Do not position the balance such that it is difficult to reach the power connection.

2. INSTALLATION
2.1 Installing Components
Refer to the illustrations and instructions below to identify and assemble your Scout balance
with its components. All components must be assembled before using the balance.
2.1.1 Releasing the Transportation Lock
2.1.2 Installing the Weighing Pan
Balances with a rectangular platform are placed into the sub-platform and rotated counterclockwise until it locks. Round platforms are placed straight down on sub-platform.
2.1.3 Security Slot
A security slot is provided at the rear of the balance allowing the balance to be secured by an
optional cable and lock accessory.
STX EN-3
2.3 Leveling the Balance
The Scout 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
balance. To level the balance, adjust the feet at each corner
until the bubble is centered in the circle.
Be sure the balance is level each time its location is changed.
See the Level Assist screen in the User Settings Menu.

Battery Compartment Cover
Interface Connection
Security Switch

Security slot (Anti-theft lock slot)
2.2 Selecting the Location
For best performance, the Scout balance should be used in a clean, stable environment. Do not
use the balance in environments with excessive drafts, with rapid temperature changes, near
magnetic fields or near equipment that generates magnetic fields, or vibrations.
2.4 Connecting Power
AC Adapter Installation
AC power is used to power the balance when battery power is not needed. First, connect the
AC Adapter (supplied) to the AC Adapter Input jack at the rear of the balance then connect the
AC plug to an electrical outlet.
Battery Installation
Install the four “AA” batteries with polarity as shown in the battery compartment.
Note:
After power on, it is recommended to let the balance warm up for at least 5 minutes before
using it.
EN-4 STX
2.5 Calibration
When the Balance is first installed, and when it is moved to another location, it must be
calibrated to ensure accurate weighing results. If preferred, the balance can be manually
calibrated with external masses. Have the appropriate calibration masses available before
beginning calibration. Refer to the Calibration and Specification Sections for masses and
calibration procedure.
