Adjusting the Percentage Up and Down:C.
After the % button has been selected (while still in
SHIFT mode), you may adjust the percentage up or
down by using the / buttons.
The minimum percentage range is 0%. The maximum
percentage range is 100%. If the percentage exceeds
the minimum or maximum percentage, the percentage
will remain in the previous percentage adjustment.
Example 1: Adjusting the Percentage Up and Down
(25%)
25%->50%->75%->100%->75%->50%->25%->0%-
>25%
Example 2: Adjusting the Percentage Up and Down

Auto Ramp Function:E.
The following is the default setup for Auto Ramp
Function:
RANGE START END DURATION
4-20mA 4mA 20mA 4 seconds
0-20mA 0mA 20mA 4 seconds
0-24mA 0mA 24mA 4 seconds
Begin the Ramp Function:
1. Press the SHIFT button followed by buttons 1, 2, or
3 for the desired range.
2. Prepare the desired START, END and DURATION
values. See instructions for each on page 18.
below.
3. After setting the START, END and DURATION
values, press the SHIFT button followed by the
AUTO RAMP (#7) button.
4. Press the #7 to restart again.
5. To return to the regular output mode, press the
SHIFT button again when the ramp function has
stopped.

Establishing the START, END and DURATION of theF.
Ramp Function:
START
1. Press the SHIFT button, then the START (#4)
button. STR will be displayed at the upper right
corner of the LCD.
2. Enter the desired value and press the ENTER
button.
END
1. Press the SHIFT button, then the END (#5) button.
End will be displayed at the upper right corner of
the LCD.
2. Enter the desired value and press the ENTER
button.
DURATION
1. Press the SHIFT button, then the SEC. (#6) button.
SEC will be displayed at the upper right corner of
the LCD.
2. Enter the desired value and press the ENTER
button. The range for duration is from 1 to 2000
seconds.
NOTE: Users should set an appropriate value for the
duration of ramp function. For a full range ramp, users
should enter at least 4 seconds for the duration.
