Electrostatic
discharge
protection
To ensure the reliability and durability of the analyzer, ESD protection precautions
must always be taken when handling or exposing ESD sensitive parts. Parts such as
printed circuit boards may be damaged if handled incorrectly during storage and
service. The damage is not visible, and the damaged parts may not fail immediately
and can take up to several months before damage is apparent.
Calibration and
measurement
While performing certain calibrations and measurements, the analyzer must be
fully assembled. A cal pack and sensor cassette may be required.
