means that E1 and E2 should have an average
pulse output frequency of 2 Hz * 72% = 1.44 Hz
and FOUT should have an average pulse output
ure 7 for all connection options). This will adjust the
CAL0 connected to:
frequency of 10 kHz * 72% = 7.2 kHz. Assuming
that FOUT is used for calibration (although the gain
error will be the same for E1 and E2), FOUT should
be measured to find the gain error. Suppose the
measured pulse output frequency is 6.966 kHz in-
stead of 7.2 kHz. 6.996 kHz is 96.76% of 7.2 kHz.
This means that the gain error is 96.76% -
100% = -3.24%. This error can be calibrated out by
connecting CAL1 to P2 and CAL0 to P2 (see Fig-

pulse rate frequency by 2.8% + 0.4% = 3.2%
(since the smallest calibration step size is 0.2%,
3.2% is the closest value that can offset the error
of -3.24). After these connections are made the a v-
erage pulse output frequency of FOUT, E1, and E2
will have a gain error less than or equal to -0.04%
of full scale.
