Specifications describe the instrument’s warranted performance over the tempera-
ture range 0°C to +55°C (unless otherwise noted). All specifications apply after
the instrument’s temperature has been stabilized after one hour continuous operation. Typical characteristics are intended to provide information useful in applying the instrument by giving typical but nonwarranted performance parameters.
These are denoted as “typical” or “nominal” and apply over the temperature
range 0°C to +55°C.
Caution: Electrostatic Discharge (ESD) can damage or destroy electronic compo-
nents. It is recommended that this preamplifier, like other electronic components,
be installed and operated at a static-free workstation or in an environment where
precautions against ESD have been implemented.
