Power connection
ATTENTION
Make sure that the voltage of the socket corresponds to the voltage given on the type plate of the
instrument. Ensure that the instrument is grounded. External connections and extension cables must
be provided with a grounded conductor lead (3-pole couplings, cable, or plug equipment) as the
mains lead has a molded plug to avoid risks due to inadvertently defective wiring. Make sure that no
electric sparks form in the instrument or its surroundings as they may damage the instrument. Make
sure that the mains connector is freely accessible at any time.
5.2.3
Calibration
NOTE
Before use it is recommended to calibrate the apparatus. Use supplied calibration substances only.
