Touch Controls: Quick, graphical access to all
control functions, applications and features.
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
Release the red transportation lock on the sub-
platform of the balance by turning the pointer
90counter-clockwise.
2.1.2 Installing the Weighing Pan
Balances with a rectangular platform are placed into the sub-platform and rotated counter-
clockwise 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.
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.

2.3 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.
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.
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.

The Scout can be used to determine an object’s density including solid and liquid.
A density determination kit (not included, buy separately) is designed to be used with Ohaus
Scout STX. However, you may use whatever lab apparatus that suits the requirements for
density measurements. The weigh below hook is recommended to use if the solids weight is
more than 200g.
Prepare the balance as shown right
1. Turn off the balance.
2. Remove the balance platform.
3. Insert they up hook and install the beaker
stand (beaker is not supplied).
4. Power on the balance
5. In the upper left portion of the home
