General Safety Measures
− Ground the instrument before operation!
− Do not disassemble any part of the device. Disassembling of the product is permitted
only to persons certified by NT-MDT Spectrum Instruments.
− Do not connect additional devices to the instrument without prior advice from an
authorized person from NT-MDT Spectrum Instruments.
− This instrument contains precision electro-mechanical parts. Therefore protect it from
mechanical shocks.
− Protect the instrument against the influence of extreme temperature, the direct impact
of sun radiation, and moisture.
− For transport, provide proper packaging for the instrument so as to avoid its damage.
Electronics
− To reduce possible influence of power line disturbances on the measurements, we
recommend supplying the instrument units with a surge filter.
− Before operation, set the power switch of the SPM controller to the position
corresponding to value of the local electrical power line (this is only done with the
controller being off!).
− Switch the SPM controller off before connecting/disconnecting its cable connectors.
Disconnecting or connecting the cable connectors during operations may cause
damage to the electronic circuit and disable the instrument. A warning label is
attached to the SPM controller of the instrument (Fig. 1-18).
