3-4-3 Value Programming
Program a value by pointing the cursor to its line and pressing the ENTER
key. Note a character or string (character string) will be blinking, ready to
be edited.
Edit the character string as follows:
1. Change character string to next value key or previous value key.
2. Move blinking character-string edit field left keyor right key
3. Press the ENTER key to save the changed value (any other key causes
the edited value to be ignored and not saved) and the original value to
be edited will remain unchanged.
When editing a character field that is blinking, the program state will be
terminated if a key is not detected within 30 seconds of the last detected
key. In this case, the value edited will not be saved, and the original value
to be edited will remain unchanged.
Measure Units
Measure units are a combination of symbols used to identify a physical
engineering measurement. The measure units may be selected from a
fixed set of customary strings. Measure Units have no arithmetic affect.
Supported measure units are listed in Section A.
Time Base
This selection is used to set the quantity per unit time (rate) measurement
as either Sec, Min, Hrs, or Days and None. The None, or scalar, time base
selection is presumed not to have a time-quantity association and does not
perform quantity accumulation.
