Thank you for selecting the Eclipse Balance from Adam Equipment.
This Instruction Manual will familiarise you with the installation, use, general maintenance
etc. of the balance, and will guide you through the various applications. It also covers
accessories, trouble-shooting, after sales service information, and other important
information.
These balances are highly accurate precision instruments and contain sensitive
mechanisms and components. They should be transported and handled with care. When
in operation, be careful to place loads gently on the weighing surface and do not overload
or exceed recommended maximum capacity of the instrument or damage may occur.
Please read this Manual thoroughly before starting operation. If you need any
clarifications, feel free to contact your supplier or Adam Equipment.
The Eclipse balances are ideal for laboratory and general purpose weighing. They can
also be used for some advanced weighing functions.
• External menu-driven calibration.
• Internal calibration (option) for outstanding accuracy without the need for manual calibration.
• Large easy to read 2-line LCD display with blue backlight, 24 mm tall primary display digits, 10
mm secondary digits, and capacity tracker bar.
•Easy to use, wipe-clean sealed keypad with pressureless capacitive-touch backlit buttons which
work with fingers, gloves or stylus.
•Force-restoration mechanism option for supreme accuracy, or alloy load cell technology option for
stable yet highly accurate weighing.
•Solid die-cast aluminium alloy construction with 304 grade stainless steel pan for durability and
easy cleaning.
•Standard applications include weighing, check weighing, percentage weighing, parts counting,
dynamic (animal) weighing, accumulation (net/total), and solid and liquid density determination.
• Bi-directional RS-232 interface and USB interface as standard.
• Can be configured to print a GLP Compliant report after each calibration to include the time, date,
balance number and a verification of the calibration.
• Automatic temperature compensation.
• Large range of weighing units, including customised option.
Carefully follow the included quick setup guide to assemble the balance. Ensure that you
locate the balance on a solid level surface, free from vibration.
6.1.1 Levelling the balance
After placing the balance in a suitable location, level it
by using the spirit level on the front of the balance. To
level the balance turn the two adjustable feet at the rear
of the balance until the bubble in the spirit level is
centred.
6.1.2 Warm-Up Time
Before you start weighing, you should allow the balance to achieve a stable internal
temperature. For accurate weighing to the manufacturer’s specification it is important to
power on the balance and allow to warm up for at least 6 hours for load cell mechanisms,
and 12 hours for force motor mechanisms.
Insert the power supply cable DC connector to the
connector on the rear of the balance. Plug the power
supply module into the mains and press the power
switch on the keypad to turn on the balance. The display
will indicate the balance serial number followed by the
software revision number, followed by the maximum
capacity of the balance. Next the balance will run a selftest by displaying all segments followed by a busy
symbol and a line of 7 dashes indicating the balance is
in busy mode. Once ready, the display will show a zero
weight reading, accompanied by the 0 symbol.
Once a suitable warm-up period is complete and you are
ready to start weighing, place an item to be weighed on
the balance. A stable symbol is shown when the
balance is in stable condition. It will turn off if the
balance is not stable.
Exact zero is shown when the “0“ symbol is visible
on the top left of the display area.

6.2 CALIBRATION
Units with an ‘i’ suffix after the model name can be calibrated using either internal
calibration mechanism or by using an external mass. Units with an ‘e’ suffix can only be
calibrated with an external mass. Internal calibration option must be enabled in the setup
menu options or else external calibration mode will be used when the [Cal] key is
pressed.
6.2.1 Manual Calibration
Pressing the [Cal] key will start calibration. Calibration can also be initiated by a change
in internal temperature or a set time period as determined by the user.
Pressing [0/T] will abort the calibration at any time.
Calibration should be performed carefully and in conditions of no vibration, air movement
or other disturbance. Make sure the pan is empty, clean, and correctly fitted.
6.2.2 Calibration using Internal Calibration mass (if fitted)
Note: Internal calibration (if fitted) will only initiate if it is enabled as the default calibration
method in the Supervisor level calibration setup menu.
On pressing the [Cal] key the display will show the busy symbol and a line of 7 dashes
and then after a few seconds will display ‘CALIBRA
dashes will reappear, followed by ‘CAL On
CAL On’. Then ‘CALIbrA

calibration and the display should return to ‘0

6.2.3 Calibration using External Calibration mass
Note: The calibration mass used should be a known accurate item, ideally with an
OIML or ASTM/ANSI classification appropriate to the accuracy of the balance.
On pressing the [Cal] key, the display will show the balance setting a new Zero condition

The display will show the busy symbol and a line of dashes, and then after a few seconds
will display the required calibration mass. For example, for a 213e model the display will

Place the selected mass on the balance and press the [Select] key to continue. The
balance will automatically continue. The display will show the busy symbol and a line of
dashes, and after calibration is complete it will sound a beep and display “UNLOAD

UNLOADUNLOAD
Remove the weight. Another beep will be heard confirming the unloading action. The
balance will display the busy symbol and a line of dashes for a few seconds and then
sound a beep and return to normal weighing.
6.2.4 Automatic Calibration
The balance will indicate the need for calibration when the balance has automatic
calibration enabled and the set pre-conditions for automatic calibration have been met.
Conditions that will trigger an automatic calibration are:
• Internal temperature change greater than a pre-set amount (typically 2ºC for
Precision balances).
• Time since last calibration exceeds a pre-set time (typically 4 hours, or 15 minutes
after power is applied).
The balance will indicate the need for calibration to be carried out by flashing the “
CAL
”
symbol on the display. As soon as the balance is calibrated the symbol will be turned off.
The Auto calibration feature can be enabled, disabled or changed within the user options
to meet the requirements of the users.
6.2.5 Calibration Errors
Occasionally during calibration an error will be detected. These errors can be caused by:
• Unstable readings
• Improper calibration weights being used
• Large shifts of zero from the factory settings
When an error is found a displayed message will be shown and the calibration must be
done again. If the balance has error messages more than once it is possible the
mechanics have been damaged.
The LCD has several areas:A large 7 digit area to display the weight with symbols for common weighing units on its
right and symbols for zero, tare (Net) and stability on the left.
A small 10-character display line above the main display area. This is used to provide
additional instructions and information on the current operation or function being used.
A capacity indicator bar at the bottom of the display.
7.1 SYMBOLS AND TEXT
The LCD has unique symbols to indicate the following:
0
dr, g/cc, g, kg, ct, mg,
Indicators:
When calibration is occurring or about to occur
For a time driven calibration
When a temperature is shown or a temperature driven
