1 KNOW YOUR BALANCEThis Instruction Manual will familiarise you with the installation, use, general maintenanceetc. of the balance, and will guide you through the various applications. It also coversaccessories, trouble-shooting, after sales service information, and other importantinformation.These balances are highly accurate precision instruments and contain sensitivemechanisms and components. They should be transported and handled with care. Whenin operation, be careful to place loads gently on the weighing surface and do not overloador exceed recommended maximum capacity of the instrument or damage may occur.Please read this Manual thoroughly before starting operation. If you need anyclarifications, feel free to contact your supplier or manufacturer.3

4 UNPACKING & ASSEMBLING THE BALANCERemove the balance from the packing by carefully lifting it out of the box. Inside the boxyou will find everything needed to start using the balance. AC mains power adapter & cordStainless Steel Top PanAlloy sub-panDraught shield (for mg models only)User documentationLocate the balance on a solid surface, free from vibration.For some models, remove the shipping protection screw and transit disc from the top ofthe balance and place the top pan support on the balance. Do not use excessive forcewhen removing and installing the screw.Gently place the pan support into the receptacle and secure with the supplied screw. Tonot over-tighten the screw. It should be finger tight only. Put the Stainless steel pan on topof the pan support.If supplied, place the draught shield frame and the top cover around the pan. 20148

5 LOCATING THE BALANCEThe balance should not be placed in a location that willreduce the accuracy.Avoid extremes of temperature. Do not place in directsunlight or near air conditioning vents.Avoid unsuitable tables. The table or floor must be rigidand not vibrate.Avoid unstable power sources. Do not use near largeusers of electricity such as welding equipment or largemotors.Do not place near vibrating machinery.Avoid high humidity that might cause condensation.Avoid direct contact with water. Do not spray or immersethe balances in water.Avoid air movement such as from fans or opening doors.Do not place near open windows or air-conditioningvents.Keep the balance clean. Do not stack material on thebalances when they are not in use. 201411

6 SETTING UP THE BALANCE6.1 First Steps6.1.1 Levelling the balanceAfter placing the balance in a suitable place, level it byusing the spirit level on the front of the balance. To levelthe balance, turn the two adjustable feet at the rear ofthe balance until the bubble in the spirit level is centred.6.1.2 Warm-Up TimeInsert the power supply cable DC connector to theconnector on the rear of the balance. Plug the powersupply module into the mains. The display will indicatethe balance serial number (if set) and the softwarerevision number, followed by the capacity of thebalance. Next the balance will run a self-test bydisplaying all segments followed by a symbol indicatingthe balance is in busy mode. If the balance serialnumber is not set the display will show dashes. Thedisplay will show zeroes accompanied by the 0 symbol.Before you start weighing, you have to wait for the balance to achieve a stable internaltemperature.A stable signis shown when the balance is in stablecondition. It will turn off if the balance is not stable.Exact zero is shown when the “ 0 “ symbol is visibleon the left of the display area.6.2CALIBRATIONUnits with an ‘i’ suffix can be calibrated using either internal calibration mechanism or byusing an external mass. Units with an ‘e’ suffix can only be calibrated with an externalmass. Internal calibration option must be enabled in the setup menu options or elseexternal calibration mode will be used when the [Cal] key is pressed.6.2.1 Manual CalibrationPressing the [Cal] key will start calibration. Calibration can also be initiated by a change ininternal temperature or a set time period as determined by the user.Pressing [ 0/T ] will abort the calibration at any time6.2.2 Calibration using Internal Calibration mass (if fitted) 201412

On pressing the [Cal] key the display will show the busy symbol and a line of dashes andthen after a few seconds will display ‘CALIbrA’. Then the busy symbol and a line ofdashes will reappear, followed by ‘CAL On’. Then ‘CALIbrA’ will appear again, followed bythe busy symbol and a line of dashes. Finally ‘CAL OFF’ will be displayed, followed by abeep and the busy symbol and a line of dashes. A final beep will sound the end ofcalibration and the display should return to ‘0.000 g’ or similar. Internal calibration is nowcomplete and normal operations may be continued.6.2.3 Calibration using External Calibration massNote: Calibration mass used should be a known accurate item, ideally with an OIMLor 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 conditionby showing “LOAd 0”. Make sure the pan is empty then press the [Setup] key to continueThe display will show the busy symbol and a line of dashes and then after a few secondswill display the default calibration mass. For example, for a “213” model (210g capacity,1mg readability) the display will be “200 g” where 200 g is the default calibration mass.Place the selected mass on the balance. The balance will automatically continue. Thedisplay will show the busy symbol and a line of dashes and after calibration is complete itwill sound a beep and display “unLOAd”. Remove the weight. Another beep will be heard
