Specifications describe the instrument’s warranted
performance over the temperature range of 0°C to
40°C (except as noted). Supplemental characteristics are intended to provide information that is
useful in applying the instrument by giving nonwarranted performance parameters.
These are denoted as “typical,” “nominal,” or
“approximate.” Warm-up time must be greater than
or equal to 30 minutes after power on for all specifications. Specifications of the stimulus characteristics and measurement accuracy are defined at
the tip of APC-7 connector on the test head connected to the instrument.
