3.2.5 Reading Configuration Menu (continued)
Reading Configuration (If Process was selected)
INPUT/READING (SCALE AND OFFSET) SUBMENU:
Input Voltage or Current can be converted or scaled into values appropriate for
the process or signal being measured. So, a reading may be displayed, for
example, in units of weight or velocity instead of in amperes or volts.
The instrument determines Scale and Offset values based on two user-provided
input values entered with the corresponding readings. Note that “In1” Input 1 and
“In2” Input 2 are represented and entered as a product of the input
voltage/current and the conversion number from the Table 3.1 .
The following instructions include details for a specific scenario in which
a 4-20 mA input (in the 20 mA Process Mode) is to be represented as a
measurement of 0-100 percent.

Press
b
&
c
14) Press
d
at the
IN.RD
prompt. Display shows
IN1
Input 1
submenu.
15) Display shows Input 1 value with first digit flashing.
16) Use
b
and
c
buttons to enter
IN1
value.
The
IN1
value = min. input value * conversion number.
Disregard the position of the decimal point (2000 counts may actually
appear as “200.0”, “20.00”, or “2.000”).
Example: 4 mA as 4(mA) x 500 = 2000.

17) Display advances to
RD1
Reading 1 Submenu.
18) Use
b
and
c
buttons to enter
RD1
value.
This value represents
IN1
in terms of some meaningful
engineering units. To show the 4 mA as zero percent enter
RD1
value = 0000.
Example: RD 1 value = 0000.
19)
Display shows
IN!2
Input 2 Submenu.
20)
Display shows Input 2 value with first digit flashing.
The
IN!2
value = max. input value * conversion number.
Example: 20(mA) x 500 = 10000 (9999).
21) Use
b
and
c
buttons to enter
IN!2
value.
22) Display advances to
RD!2
Reading 2 Submenu.
23) Use
b
and
c
buttons to enter
RD!2
value.
Example: RD 2 value = 0100.
24) Display flashes
STRD
stored message momentarily and
then advances to
ALR1
only, if change were made, otherwise
press
d
to advance to
ALR1
Alarm 1 Menu.
