Decrements the selected digit (values roll over from 0 to 9).
Accepts the modified value as the current engineering unit zero or full-scale
(FS) value.
(k) Touch to increment the least significant digit to the desired valued (the digits roll over
from 9 to 0).
(l) Touch to move to the next digit.
(m) Touch to increment the selected (blinking) digit to the desired valued (or Touch

example, set to 200.
(o) Touch to accept the entered value as the engineering units zero value.
The alphanumeric display shows “Eng units 0 value”. The numeric display shows the
current engineering unit zero value.
(p) Touch to move to the next menu item.
The alphanumeric display reads “Eng units FS value”.
(q) Touch to set the Full Scale (FS) value.
The numeric display shows the current engineering unit FS value with the least significant
digit blinking.
(r) Repeat Steps (k) through (o) set the engineering units FS value (in this example, set to
400).
(s) Touch to end the engineering units setting process.
