1 KNOW YOUR BALANCE
Thank you for selecting the Nimbus 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.

2 PRODUCT OVERVIEW
The Nimbus balances are ideal for laboratory and general purpose weighing. They can also be used for some advanced weighing functions.
FEATURES:
External menu-driven calibration allowing user-selectable range of calibration weights.
Internal calibration (option) for outstanding accuracy without the need for manual calibration.
Mains powered, with some models offering rechargeable battery pack option for cordless use.
Solid die-cast aluminium alloy construction with 304 grade stainless steel pan for durability and easy cleaning.
Large easy to read LCD display with backlight.
Standard applications include weighing, percentage weighing, parts counting, dynamic (animal) weighing (not ‘j’ models), and solid and liquid density determination.
Bi-directional RS-232 interface and USB interface as standard.
External display option
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.
Force-restoration mechanism for supreme accuracy, or alloy load cell technology for stable yet accurate weighing.
Automatic temperature compensation.
Multiple weighing units.
Easy to use, wipe-clean sealed membrane keypad.
Below balance weighing facility (accessory hook required).
Display in a choice of 4 languages – English, German, French & Spanish.
Password protection.
Security locking point.

4 UNPACKING THE BALANCE
Remove the balance from the packing by carefully lifting it out of the box. Inside the box you will find everything needed to start using the balance-
AC mains power adapter & cord
Stainless Steel Top Pan
Alloy sub-pan
Draught shield (for mg models only)
User documentation
Carefully follow the quick setup guide included to assemble the balance.
5 LOCATING THE BALANCE
The balance should not be placed in a location that will reduce the accuracy.
Avoid extremes of temperature. Do not place in direct sunlight or near air conditioning vents.
Avoid unsuitable tables. The table or floor must be rigid and not vibrate.
Avoid unstable power sources. Do not use near large users of electricity such as welding equipment or large motors.
Do not place near vibrating machinery.
Avoid high humidity that might cause condensation.
Avoid direct contact with water. Do not spray or immerse the balances in water.
Avoid air movement such as from fans or opening doors. Do not place near open windows or air-conditioning vents.
Keep the balance clean. Do not stack material on the balances when they are not in use.
Avoid sources of static electricity. This can affect measurement accuracy and may damage sensitive electronics.

6 SETTING UP THE BALANCE
6.1 ASSEMBLING THE BALANCE
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.
6.1.3 Weighing
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.

6.2CALIBRATION
Units with an ‘i’ suffix 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 ‘ ’. Then the busy symbol and a line of 7 dashes will reappear, followed by ‘ ’. Then ‘ ’ will appear again, followed by
the busy symbol and a line of dashes. Finally ‘ ’ will be displayed, followed by a beep and the busy symbol and a line of dashes. A final beep will sound the end of
calibration and the display should return to ‘ . g’ or similar. Internal calibration is now complete and normal operations may proceed.
6.2.3 Calibration using External Calibration mass
Note: 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 by showing “ ”. Make sure the pan is empty then press the [Setup] key to continue
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
be “ g” where 100 g is the required calibration mass.
Place the selected mass on the balance. 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 “ ”. 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:

14 |
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.
