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 0-100percent.

14) Press d at the IN.RD prompt. Display shows IN1 Input 1 Submenu.

15) Display shows Input 1 value with 1st 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 “2000”, “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: RD1 value = 0000.

19) Display IN2 Input 2 Submenu.

20) Display shows Input 2 value with 1st digit flashing. The IN2 value = max. input value * conversion number. Example: 20(mA) x 500 = 10000 (9999).

Press b & c 21) Use b and c buttons to enter IN2 value. Press d 22) Display advances to RD2 Reading 2 Submenu. Press b & c 23) Use b and c buttons to enter RD2 value.

Example: RD2 value = 0100.

24) Display flashes STRD stored message momentarily and then advances to ALR1 only, if change was made, otherwise press d to advance to ALR1 Alarm 1 Menu.
