Before making any changes, first check the signal inhibit status field (See Figure 12). When
the display shows ME (manual enable) you can change variable parameters. When it shows
MI (manual inhibit), you cannot alter the parameters of this variable. If the field indicates
MI, press the OPER I/E key to change it to ME.
To change an analog value:
Press CHNG (F3) to clear the third line. Use the number keys 0 through 9 to enter the
new value. The minus sign and period are also permitted. Press [ENTER].
If you make a mistake, press CHNG (F3) and enter the number again or use the [DEL]
key to erase a character.
Another way to enter new values is by using the arrow up and arrow down keys (located
below the [F3] key and left of the [INIT] key). These keys will raise and lower the value
by 1% of the displayed amount.
To change the status of a logical variable:
Press CHNG (F3), then use either the down and up arrow keys or the [0/OFF] and
[1/ON] keys to change the state of a logical variable. If the [0/OFF] and [1/ON] keys are
used, you must also press [ENTER].
