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 mAProcess Mode) is to be represented as a
measurement of 0-100 percent.
Press d14) Press dat the IN.RD prompt. Display shows IN1 Input 1
submenu.
Press d15) Display shows Input 1 value with 1st digit flashing.
Press b& c16) Use band cbuttons to enter IN1 value.
The IN1 value = min. input value * conversion number.
Disregard the position of the decimal point, such that 2000
counts may actually appear as “200.0”, “20.00”, or “2.000”.
Example: 4 mA as 4(mA) x 500 = 2000.
Press d17) Display advances to RD1 Reading 1 Submenu.
Press b& c18) Use band cbuttons to enter RD1 value.
This value represents IN1 in terms of some meaningful
engineering units. To show the 4 mAas zero percent enter RD1
value = 0000.
Example: RD1 value = 0000.
Press d19) Display IN!2 Input 2 Submenu.
Press d20) Display shows Input 2 value with 1st digit flashing.
The IN!2 value = max. input value * conversion number.
Example: 20(mA) x 500 = 10000 (9999).
Press b& c21) Use band cbuttons to enter IN!2 value.
Press d22) Display advances to RD!2 Reading 2 Submenu.
Press b& c23) Use band cbuttons to enter RD!2 value.
Example: RD!2 value = 0100.
Press d24) Display flashes STRD stored message momentarily and
then advances to ALR1 only, if change was made, otherwise
press dto advance to ALR1 Alarm 1 Menu.
