For a non-inverting amplifica-
tion with external adjustments,
when the combined resistance of
the span adjustment and 9kΩ is
10kΩ, the gain is (1 + 10kΩ / R

. With the span adjustment
(2kΩ), the output is configurable.
The zero is adjustable with a ref-
erence voltage source of ±15V DC
and the attenuation of 200Ω and
30kΩ.

MAINTENANCE
Regular calibration procedure is explained below:
■
CALIBRATION
Warm up the unit for at least 10 minutes. Apply 0%, 25%,
50%, 75% and 100% input signal. Check that the output
signal for the respective input signal remains within accu-
racy described in the data sheet.
