Table 4-3. Analog Input (ANI) Module
Purpose: This module is used to configure the voltage/current input signals (e.g., 0-5 volts
[0-20 mA], 1-5 volts [4-20 mA]) and how the input signals are interpreted (linear or square root
representation, with or without smoothing ). It is also used to configure the vertical axis range
(zero and span) on the display.

0 This is the value in engineering units of the
measured input after all signal conditioning
has been applied.

100 This determines the upper range the analog
input represents in engineering units. The
upper range value equals Engineering Zero
plus Engineering Span.

3 This controls a first order filter that is applied
to the input signal. The time constant is
entered as an index value as follows:
0 - No Smoothing (no effect)
1 - 0.05 s 6 - 3.1 s 11 - 102 s
2 - 0.1 s 7 - 6.3 s 12 - 205 s
3 - 0.3 s 8 - 12.7 s 13 - 410 s
4 - 0.7 s 9 - 25.5 s 14 - 819 s
5 - 1.5 s 10 - 51.1 s 15 - 1638 s
0 - 5 V Input NOBIAS0

ANI1 L416
L417 0
0 Setting this parameter to 1 indicates the input
range is from 0 - 5 volts (0 - 20 mA); 0
indicates the input range is from 1 - 5 volts (4 -
20 mA).
Square Root
Signal SQRT0
SQRT1 ANI0
ANI1 L440
L441 0
0 When a 0, it indicates the analog input signal
should be interpreted linearly.
When 1, it indicates the analog input signal
should be interpreted as a square root
representation of the value.
When square root is selected, input signals
less than 1% (10% input range) force the input
to its zero value.

B264 This is the calibration zero adjustment. This
parameter is factory set and should not
need adjustment under normal operation.
See Section 5.3 for calibration information.

ANI1 C296
C297 This is the calibration span adjustment. This
parameter is factory set and should not
need adjustment under normal operation.
