Getting Started

Storage and Shipping Conditions

Allowable storage temperature: +5 ...+40°C | +41 ... +104°F

The packaging has been designed to ensure that the balance will not be damaged even if it is dropped from a height of 80 centimeters (about 32 inches). Do not expose the balance to extreme temperatures, jolts, impact, vibration or moisture.

Unpacking the Balance

§After unpacking the balance, check it immediately for any visible damage as a result of rough handling during shipment

$If this is the case, proceed as directed in the chapter entitled “Care and Maintenance,” under the section on “Safety Inspection”

It is a good idea to save the box and all parts of the packaging until you have successfully installed your balance. Only the original packaging provides the best protection for shipment. Before packing your balance, unplug all connected cables to prevent damage. The strip of cardboard between the display and control unit and the weighing platform is important for protecting the equipment during shipment!

Installation Instructions

The ME/SE balances are designed to provide reliable weighing results under normal ambient conditions 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 temperature inside the draft shield (greenhouse effect), resulting in incorrect readouts due

to 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 Transport

After transporting the balance, its linearity may be outside the allowable tolerances (please refer to the “Specifications” in the “Overview” chapter). After transporting the balance, be sure to perform internal linearization. Repeat this process to obtain optimal accuracy. 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 brought into a substantially warmer place. If you transfer the balance to a warmer area, make sure to condition it for about 2 hours at room temperature, leaving it unplugged from AC power. Afterwards, if you keep the balance connected to AC power, the continuous positive difference in temperature between the inside of the balance and the outside

will practically rule out the effects of moisture condensation.

–AC adapters with a registered approval rating from a national testing laboratory

$To use a main feeder cable from the ceiling or to mount a CEE plug, have a certified electrician install it

$To use an external rechargeable battery pack, refer to the “Accessories” in the “Overview” chapter

§ Insert the AC adapter plug with the angle facing downward into the jack on the balance

14

§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 balance is disconnected from AC power, the balance-generated data will remain stored for approximately three months. In the standby mode, data is retained in the memory via the power supply. Be sure to print out data before storing your balance for a relatively long period.

Safety Precautions

The AC adapter rated to Class 2 can be plugged into any wall outlet

without requiring any additional safety precautions. The ground or earth terminal is connected 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 digital device, pursuant to Part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense. Changes or modifications not expressly approved by Sartorius AG could void the user‘s authority

to 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 Time

Each time you move your balance to another location, you must condition it for at least 12 hours to the new location. To deliver exact results, the balance must warm up for at least 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 57.
