Installation InstructionsThe ME/SE balances are designed to provide reliable weighing results under normal ambientconditions in the laboratory and in industry. Choose the right location to set up your balance

by observing the following so that you will be able to work with added speed and accuracy: Set up the balance on a completely even surface on a low-vibration balance table or

wall console Avoid placing the balance in close proximity to a heater or otherwise exposing the

balance to heat or direct sunlight, as this can considerably increase the temperatureinside the draft shield (greenhouse effect), resulting in incorrect readouts dueto convection currents, turbulence and buoyancy effects.

Protect the balance from drafts that come from open windows or doors Avoid brief fluctuations in room temperature Protect the balance from aggressive chemical vapors Do not expose the balance to extreme moisture

Linearization after TransportAfter transporting the balance, its linearity may be outside the allowable tolerances(please refer to the Specifications in the Overview chapter). After transporting thebalance, be sure to perform internal linearization. Repeat this process to obtain optimalaccuracy. For directions on this procedure, please refer to the section on Linearization.

Conditioning the Balance

Moisture in the air can condense on the surfaces of a cold balance whenever it is broughtinto a substantially warmer place. If you transfer the balance to a warmer area, makesure to condition it for about 2 hours at room temperature, leaving it unplugged fromAC power. Afterwards, if you keep the balance connected to AC power, the continuouspositive difference in temperature between the inside of the balance and the outsidewill practically rule out the effects of moisture condensation.

Setting Up the Balance ME215/235/254/414/614 Place the components listed below inside the weighing chamber in the order given: 1) Shield plate 2) Position the weighing pan and turn to the left or right until it snaps into place 3) Shield disk (ME235S/P only)

$ Note: the shield disk minimizes the effects of drafts within the weighing chamber

Remote Operation of the Display and Control Unit Unplug the cables, turn the balance on its side and lay it on a padded surface

to avoid damaging the weighing system and draft shield

Use an Allen wrench to remove the three fastening screws

Remove the display unit and attach the connecting cable

> Length of the connecting cable: 44 cm (17 inches)

$ For information on longer cables, please see the Accessories section

Plug power cord into the AC adapter

To power the balance with AC current, plug the power cord into

a wall outlet (mains supply)

Charging the Rechargeable Battery for Saving Data:All data is saved in the battery-backed memory. When initially operating the balance,leave it connected to AC power for one day to charge the battery. When the balanceis disconnected from AC power, the balance-generated data will remain stored forapproximately three months. In the standby mode, data is retained in the memory viathe power supply. Be sure to print out data before storing your balance for a relativelylong period.

Safety PrecautionsThe AC adapter rated to Class 2 can be plugged into any wall outletwithout requiring any additional safety precautions. The ground or earth terminal isconnected to the scale housing, which can be additionally grounded, if required.The data interface is also electrically connected to the balance housing (ground).

Note:This equipment has been tested and found to comply with the limits for a Class A digitaldevice, pursuant to Part 15 of the FCC rules. These limits are designed to providereasonable protection against harmful interference when the equipment is operated ina commercial environment. This equipment generates, uses and can radiate radiofrequency energy and, if not installed and used in accordance with the instructionmanual, may cause harmful interference to radio communications. Operation of thisequipment in a residential area is likely to cause harmful interference in which case theuser will be required to correct the interference at his own expense. Changes ormodifications not expressly approved by Sartorius AG could void the users authorityto operate the equipment.

Connecting Electronic Peripheral Devices Make absolutely sure to unplug the balance from AC power before you connect or

disconnect a peripheral device (printer or PC) to or from an interface port

Warmup TimeEach time you move your balance to another location, you must condition it for at least12 hours to the new location. To deliver exact results, the balance must warm up for atleast 12 hours after initial connection to AC power. Only after this time will the balance

have reached the required operating temperature.

Using Balances Verified as Legal Measuring Instruments in the EU*:$ The balance must warm up for at least 24 hours after initial connection

to AC power

$ Warmup time each time power is turned on the ME614S-0CE, ME414S-0CE:at least 30 minutes

$ Always wait for the power-on adjustment routine to be completed:for requirements see page 63.

Antitheft Locking DeviceTo fasten an antitheft locking device, use the lug located on the rear panelof the balance.

Secure the balance at the place of installation, e.g., with a chainor a lock

Leveling the BalancePurpose:

To compensate for unevenness at the place of installation

To achieve perfectly horizontal positioning of the balance for consistent repeatabilityof the weighing results

Always level the balance again any time it has been moved.

Only the 2 front feet are used for leveling.

Turn the leveling feet as shown in the diagram until the air bubble is centered exactlywithin the circle of the level indicator

> Several leveling steps are usually required

$ The balance must be disconnected from power before preparing it for shipment.Disconnect the AC adapter and all interface cables from the balance.

Transport Over Short Distances Place one hand under the display and control unit and the other under the back of the

balance. Lift the balance carefully and carry it to the new location.

$ Avoid subjecting the balance to vibration or shocks (impact).

! Do not lift the balance by the draft shield or the front panel, as this can result

in damage.

Transport or Shipping Over Long DistancesMake sure you use all components of the original packaging in the following cases:

for transport or shipping over long distances. if it is not certain that the balance will remain upright during transport or shipping.

Remove the following parts: Shield disk (included with ME235S/P models only) Weighing pan and shield plate:

Reach beneath the shield plate and lift it carefully, together with the weighing pan,to avoid damaging the weighing system.

Open the draft shield doors and carefully position the balance in the lower packaging. Press the foam padding against the housing.

General Instructionsfor Analytical Weighing

Handling Samples and ContainersThe sample should be conditionedto the temperature inside the balance.This is the only way to avoid errorscaused by air buoyancy and deviations

caused by convection currents at thesurface of the sample.

Since these effects increase proportion-ally to the volume and surface of thesample, make sure that the size of thetare vessel selected is appropriate forthe initial sample.

Never use your bare hands to touchsamples to be weighed. In addition tothe effect of the temperature, theextremely hygroscopic behaviorof fingerprints left on the sample willotherwise cause considerable inter-

ference during weight measurement.

Use forceps or a similar utensil that isappropriate to place your sample care-fully on the pan. Working with yourbalance requires a steady hand and asmooth, uninterrupted technique.

If the weighing chamber has not beenopened for a relatively long period,it may have a temperature differentfrom that of the balances surroundingenvironment. When you open theweighing chamber, a change in temp-erature will inevitably occur, due to the

laws of physics, and may show up asa change in the weight readout.

Operating the Balance

Therefore, we recommend that beforeyou begin the actual weighing series youopen and close the weighing chamber at

the same rate as you will be doing duringweighing. After the weighing chamberhas been closed, the weight readout willusually stabilize after about 8 seconds.The accuracy of the weight readouts willincrease as you continue weighing withgreater consistency.

Weighing Electrostatically ChargedSamples and ContainersMajor measuring errors can occur whenelectrostatically charged samples andcontainers are weighed. This problemparticularly involves samples that haveextremely poor conductivity (glass, plastic,filters) since they can discharge electro-static i.e., friction-induced charges onlyover a relatively long period of time. Theresult is an interaction of forces among thecharges adhering to the sample and thestationary components of the balance(weighing chamber base plate, draft shieldconstruction, balance housing). This isnoticeable when the weight readout drifts.At high humidity, this effect is notvery pronounced or may not occur at all,due to the thin layer of water thatcondenses on the sample and, through

conductive discharge, counteractsinterfering static electricity.

In addition to taking purely mechanicalcounteractive measures (protecting thesample using a special antistatic weighingpan see the Accessories), you canneutralize the surface charges bybombarding them with ions of theopposite polarity (see page 53 forinstructions on activating the ionizer).This is a highly effective procedurefor eliminating static electricity.

The balances environment, including the

operator, can considerably interfere withweighing results, due to static electricity.The balances of the ME/SE series havebeen designed to counteract this phenom-enon: the glass surfaces of the draft shieldhave a special metallic coating.

The rear panel of the balance has aterminal for connecting an equipotentialgrounding conductor. It is used foradditional grounding of a peripheraldevice (for example, a vibrating spatula).This terminal is designed for singlegrounding wires up to .25 standardgauge or 6 mm2 stranded wires and for .18

standard gauge or 4mm2

stranded wires.

Weighing Magnetic or MagnetizableSamples

It is technically impossible to avoid the useof magnetizable materials in the manufac-ture of balances. Ultimately, the operatingprinciple of high-resolution balances isbased on electromagnetic force compensa-tion of the load placed on the weighingpan.

When magnetic or magnetizable samplesor containers (e.g., a beaker with a stirrer)are weighed, interactions among theabove-mentioned components of thebalance may occur, distorting weightreadouts.

Unlike deviations caused by electrostaticcharges, magnetic interference is usuallyconstant over time. However, it is sensitiveto and dependent on the position of thesample container on the weighing pan andis also characterized by poor repeatability.

To reduce the effect described above,we recommend increasing the distancebetween the sample and the weighing panby inserting a non-magnetizable materialbetween them (the reduction in force isproportional to the quadrate of the distance).In special cases, soft-magnetic plates

should be used to shield against interferingmagnetic effects.

In the presence of extremely strongmagnetic fields for instance, whenmeasuring the susceptibility of a samplein an electromagnet you should usethe below-balance weighing port, whichcomes standard on your balance.
