NOTES
1
The digital input specifications are 100% tested at +25
°
C, and guaranteed but not tested over the full temperature range.
2
Adjustable to zero.
3
FSR means “Full-Scale Range” and is 20 V for
±
10 V range and 10 V for the
±
5 V range.
4
A minimum power supply of
±
12.5 V is required for a
±
10 V full-scale output and
±
11.4 V is required for all other voltage ranges.
Specifications subject to change without notice.
Specifications shown in
boldface
are tested on all production units at final electrical
test. Results from those tests are used to calculate outgoing quality levels. All min and
max specifications are guaranteed, although only those shown in boldface are tested
on all production units.
