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.
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)

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
$ If you wish to use a longer cable, it must be installed by authorized
Sartorius service technicians
