On the installation site observe the following:
ƒ The load must be lifted clear of the display unit’s case and other pallets.
Incorrect lifting of a load Correct lifting of a load
ƒ The accuracy of the weighing system is falling by approximately 0.1 % per
degree if there is a slant of more than 2°. Holes and unevenness, too, have
this effect. A smooth floor is ideal.
ƒ Optimum accuracy in weighing results is achieved if the load centre is
between the forks. The forks are easily bent and twisted when the load is off-
center. This may result in diminished accuracy.
In verifiable models off-centre loads, or slants affecting accuracy, activate the
inclination switch which in turn disconnects the display.
Non-optimal positioning of load Optimal positioning of load
ƒ Temperature range: The maximum deviation for 0.1% of the weighed load is
between -10 and +40°C. Outside this temperature range deviations of up to
0.3% may occur.
ƒ Avoid jarring during weighing
ƒ Protect the balance against high humidity, vapours and dust
ƒ Do not expose the device to extreme dampness for longer periods of time.
Non-permitted condensation (condensation of air humidity on the appliance)
may occur if a cold appliance is taken to a considerably warmer environment.
In this case, acclimatize the disconnected appliance for ca. 2 hours at room
temperature.
ƒ Because condensed water may arise in the electronic system, fast
temperature changes should be avoided. For acclimatization the balance
should be switched off in case of larger temperature differences.
ƒ Major display deviations (incorrect weighing results) may be experienced
should electromagnetic fields (e.g. due to mobile phones or radio equipment),
static electricity accumulations or instable power supply occur. Change
location or remove source of interference.
