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 d

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

 

 

submenu.

Press d

15)

Display shows Input 1 value with 1st digit flashing.

Press b & c 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.

Press d

17)

Display advances to RD1 Reading 1 Submenu.

Press b & c 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.

Press d

19)

Display IN!2 Input 2 Submenu.

Press d

20)

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 & c 21) Use b and c buttons to enter IN!2 value.

Press d

22)

Display advances to RD!2 Reading 2 Submenu.

Press b & c 23) Use b and c buttons to enter RD!2 value.

 

 

Example: RD!2 value = 0100.

Press d

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.
