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.

1.3 Safety Precautions

Caution: Read all safety warnings before installing, making connections, or servicing

this equipment. Failure to comply with these warnings could result in personal injury

and/or property damage. Retain all instructions for future reference.

 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.

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.

4.5 Density Determination

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

screen select Density Determination.

6. Follow below instructions to determine the

object’s density.

Determination home screen.

To begin the Density Determination process,

press

Start

.

Step 1 of 2 – Weigh the Sample in Air.

Press Start. Follow screen instructions, and then press Accept to store the dry sample weight

(“in air”).

Step 2 of 2 – Weigh the Sample Submerged in the Liquid.

Follow the screen instructions, then press Accept to store the sample weight (submerged in

liquid).

(along with the weight

in air, weight in water) on the Application

screen.

Press

Start

to reset all the weight values and restart the process.

The balance can also be used to measure the Density of a Buoyant Material Using Water.

Follow the same procedure as Solid Material above, except in Density Determination step 2,

push the sample down (requires special tool, not supplied) into the liquid until it is fully

submerged.

4.5.2 Measuring the Density of a Solid Using an Auxiliary Liquid

To enable this feature, enter the Item Settings screen and select the following:

 Density Type: Solid

 Auxiliary Liquid: Other

 Porous Material: Off

Confirm the default values displayed (Liquid Density, etc) are correct.

Begin the Density determination process by pressing Start and following the screen

instructions.

4.5.3 Measuring the Density of a liquid using a Calibrated Sinker (not

supplied)

Enable this feature, enter the Density Item Settings screen and select the following;

 Density Type: Liquid

Note: when the Density Type is set to Liquid, the

Liquid type and Porous material selections are

disabled.
