InstallationPreparationThis product is intended for indoor use.Select a level, rigid work area that is free from drafts andvibrations (i.e. away from doors, windows, air conditioningand heating vents).The line voltage to the balance should be reasonably constant(+/-10%) and free from fluctuations.Position balance to allow the removal of the power adapterplug from the wall outlet. It is not advisable to use an outletthat is shared with fluorescent fixtures or other electricalequipment that draws current in an inconsistent manner.Do not locate the balance near magnetic materials, or nearinstruments that incorporate magnets in their design. Avoidareas that experience extreme highs, lows or fluctuations inroom temperature. Excessive temperatures that may affectbalance operation and accuracy are 1) above 105°F (40°C)and 2) below 60°F (15°C).WeighPanDisplayOn/OffBubbleLevelIndicator24.788WEIGH Select Mode PrintZ E R OgDisplayOn/OffLevelingFootLevelingFoot3

SetupCarefully remove the balance and all accessories from thecarton. There are no tie-downs; however there may be packingmaterials under the pan support (square-pan models only).LEVELING THE BALANCE1. The leveling feet are located on the bottom of the balance.Do not turn the balance over. Viewing the balance fromabove, turn all leveling feet counterclockwise until the feetare fully retracted into the balance base.2. Note the position of the bubble on the leveling vial.For maximum weighing accuracy, the bubble should belocated inside the black ring. Some adjustment will likely benecessary.3. Begin with the foot that is opposite of the location of thebubble and turn clockwise until the bubble is moved intothe black ring. If necessary, repeat this step with the otherleveling feet until the bubble is positioned in the center ofthe black ring.4. Avoid extending the level feet too far. If it seems necessaryto do so, it is likely that the tabletop is not level. Check thesurface on which you have placed the balance; it may benecessary to choose another location.NoteMemo:The bubble moves TOWARD a foot when that foot isturned CLOCKWISE. The bubble moves AWAY from afoot when that foot is turned COUNTERCLOCKWISE.POWERING THE BALANCEWARNINGVerify that you have received the proper voltagepower supply for your country of use!Insert the power cord into the receptacle located at the backof the balance and plug the power adapter into a wall outlet.The display will perform a quick test in which all segments arebriefly illuminated and display “stabilizing” for 30 seconds.INITIAL WARM-UP PERIODAfter the initial power-up, it is necessary to allow a minimum of3 to 5 hours for the balance components to become warmand for the internal temperature to stabilize.4!

It is not necessary to unplug your balance from the powersource when it is not in use. It is advised to leave the unitplugged in so that all components are warm and the balanceis ready to weigh at any time. If you wish, the display can beturned off to save the segment life, by simply pressing theDisplay On/Off button.WEIGH PAN INSTALLATIONWARNINGMishandling the balance weigh pans cancause serious mechanical damage!The balance weigh pan engages critical and delicatemechanical components inside the balance. Please observethe following precautions when handling the weigh pans:1. Do not apply manual pressure to the weigh pan at any time.2. Do not bump the pan.3. Do not drop objects onto the pan.4. Do not attempt to clean or vigorously wipe the pan while it isinstalled on the balance.ROUND-PAN MODELSBalances with 3.5” or 4.5” round pans feature a weigh panassembly that consists of an aluminum pan and an impact protectionring that helps to shield the weigh pan from lateralshocks. (For models with 6” pans, simply place pan on panstem.)1. Place the impact ring on the balance first.2. Center the weigh pan over the impact ring and gently slideor twist (do not push) the pan onto the pan stem.3. When removing the pan for cleaning, remove the impactring first and then pull the weigh pan straight up and off(pulling the pan at an angle could result in mechanicalbreakage).SQUARE-PAN MODELSSimply place the square top-pan on the pan support.You’re ready to begin weighing!!5

CalibrationYour balance was calibrated at the factory; however, it is necessaryto re-calibrate upon setup and on a regular basisthereafter. The factory recommendation for calibration isonce per week using the maximum permissible weight standard.Reasons for more frequent calibration include 1) movingthe balance, 2) organizational procedures, 3) special samples/applicationswhich require documented calibrationtime/date stamp.Your balance may be calibrated with the internal weight orwith an external mass standard. In the External mode the balancewill recognize the calibration weight as one of the permissibleweight values, whereas in the Manual mode an exactcertified value of the calibration weight is entered.PERMISSIBLE WEIGHTSModelWeight20 30 50 60 100 200 300 400 500 600 1000 2000 400064 X X X X104 X X X X X204 X X X X203 X X X X403 X X X X402 X X X X602 X X X X X X2102 X X X X X4102 X X X X2101 X X X X X4101 X X X X603D X X X X X X X4102D X X X X X XEXTERNAL CALIBRATION (using a mass standard)Be certain that the balance has stabilized.1.
