Requirements
NOTE: Read the warnings and safety information at the start of this manual before you
install the instrument. They contain important information.
Electrical requirements
The Spectrum 100 FT-IR and Spectrum 100N FT-NIR spectrometers can operate on
electricity supplies of 50 or 60 Hz and in the 100 to 230 V range without any adjustment.
The nominal power consumption of the instrument is 120 VA.
The line supply must be within 10% of the nominal voltage.
If possible, do not connect the instrument to circuits that have heavy duty equipment
connected, such as large motors.
If possible, do not use photocopiers, discharge lamps, radio transmitters, and other
equipment with large or frequent transient loads on the same supply circuit.
The primary fuse (2AT, 250 V) is in the drawer on the rear of the instrument next to the
mains inlet: the spare fuse is in the same drawer. The primary fuse is connected in the
live line.
Environment
To obtain the best performance from your instrument:
• Place the instrument in an environment that is relatively dust-free.
• Make sure that the bench top is free from vibration or mechanical shocks.
• Do not place the instrument or the PC near to room heating equipment, such as
central-heating radiators.
• Do not position the instrument in direct sunlight as this may cause overheating.
• Leave at least 15 cm (6 inches) from any surface and the cooling louvers at the rear
of the instrument.
• Leave at least 7 cm (3 inches) from any vertical obstacle to the sides of the
instrument, to permit an adequate flow of cooling air.
• Make sure that there are no overhanging shelves, and no water pipes or faucets that
could leak onto the instrument.
• The area near the PC must be free of strong magnetic fields, direct sunlight, and
heating or cooling units or ducts.
The instrument has been designed for indoor use and operates correctly under the
following conditions:
Ambient temperature 15 °C to 35 °C
Ambient relative humidity 75% maximum (non-condensing)
