ESA Series Precision Balance

Thank you for purchasing the Model ESA precision balance. Please read all
operating instructions carefully before using and note the following items to
ensure accurate readings.

1.0 Description

• The ESA balances use a high precision load cell and microcomputer for

simple operation with accurate, stable weight readings displayed on the
large liquid crystal display.

• This balance is an excellent choice for laboratory use and educational
applications, however, it is not recommended for use in production lines,
food preparation areas or any other environment where high heat, cold,
humidity or vibration are present.

• Do not overload the balance. This will damage the load cell and void the
warranty.

• Inspect the platter, draft shield, housing and AC adapter regularly for
damage.

• Refer to the troubleshooting chart at the end of this manual for more
details.

• Do not attempt to repair the balance if you have a problem. Contact your
local Salter Brecknell representative.

2.0 Unpacking

Please check the contents of this box carefully. Your ESA balance should
come with one of each of the following:

• Electronic Balance

• Stainless Steel Weighing Platform

• 6V AC Power Adapter

• User Manual

3.0 Installation

• Place the balance on a stable, level surface.

• Connect the AC adapter to an appropriate power outlet.

Note: Y

ou can also operate this unit using batteries instead of the supplied

AC adapter. Batteries are not included with the unit.

4.0 Key Functions

The following figure shows the front panel with six keys. Each key function is
explained here.

On/Off Turns the balance on or off or returns balance to normal weighin g

mode.

Count Places the balance in piece count mode.
Cal (stands for Calibrate) Enters calibration mode.
Tare Used to tare off, up to 100% of balance capacity, an empty

container and to reset the balance to zero. Use of tare with a
weight or container reduces the scale’s capacity by the tare value
stored. Also works like Enter in some modes.

Mode Toggles the backlight on or off. To extend battery life, turn

backlight off. Also toggles between options in calibration mode.

Units Allows you to scroll through and select from the available units (g,

oz, ozt, dwt, lb) as well as count (ct) and percentage (%).

5.0 Scale Operation

This section covers the scale operations of weighing and counting.

Note: Always make sure that the balance is on a clean, dry, level and solid

surface.

Simple Weighing

1. Turn the balance on. The balance will go through a series of tests and

then display all zeroes (0’s).

2. Press the Units key until the desired unit of measure is displayed on the

far right of the display.

3. Press the Tare key if the display no longer reads zero.

4. Place item(s) to be weighed on the weighing platform. The weight will

be displayed with the appropriate unit of measure next to it.

5. Remove the item(s) from the balance and repeat steps 2 - 5 to continue

weighing.

Tare Weighing

If you want to do net weighing, such as weighing objects in a container, follow
these steps.

1. Turn the balance on. The balance will go through a series of tests and

then display all zeroes (0’s).

2. Press the Units key until the desired unit of measure is displayed on the

far right of the display.

3. Place the container to be tared on the weighing platform and press the

Tare key. The display should return to zero.

4. Place item(s) to be weighed in the container. The weight will be

displayed with the appropriate unit of measure next to it. The weight
displayed is the net weight and does not include the weight of the
container.

5. Remove the item(s) from the container and repeat steps 3 - 5 to

continue weighing with the same container.

Note: If you

remove the container, the balance will show a negative weight.

Press the Tare key to return the balance to zero.

6

General Counting Function

The ESA series will count parts based on the weight of a reference sample of
5, 10, 20, 30, 40 or 50 pieces. For best results, the pie ces used should be of
equal weight. Also, the larger the sample, the more accurate your counts will
be. Once you have created this reference sample, it will remain in memory
until a new sample is recorded, even when the balance if turned off. This
section explains the counting function in further detail.

1. Turn the balance on and allow it to come to zero.

2. Press the Count key. The balance will display “CON pcs”.

Note: If you are using a cont ainer to hold the pieces, place the empty
container on the weighing platform at this point.

3. Press Tare. The balance will display the message “Add 5”.

4. Press Mode until the number of pieces in your sample is displayed. You

can choose from 5, 10, 20, 30, 40 or 50.

5. Place your sample on the platform and press Tare.

6. There will be a short pause and then the balance will show the number

of the sample on the screen.

Note: If

the balance displays the message “PC Err”, the sample size was too

small for the balance and a larger sample will be required.

7. Remove the sample from the balance. The balance is now ready to

8. Add pieces to the balance / container. The balance will show the

number of pieces on the display.

9. Press the Units key to exit piece counting and return to normal

weighing. You can return to piece counting by pressing the Units key
until “pcs” is displayed.

6.0 Calibration

Occasionally, you may need to calibrate your balance with an appropriate
weight. There are two types of calibration possible: sensitivity calibration and
linear calibration. Linear calibration should only be attempted by a qualified
service technician with correct weights. This section explains how to perform
each type of calibration.
